Energy Reference Design from Texas Instruments. After reading this user's guide, a user should better understand the features and usage of this reference design platform. SNOA922April 2013 Submit Documentation Feedback Copyright 2013, Texas Instruments Incorporated Gas Sensor Platform Reference Design User's Guide 5 Introduction www.ti.com The Gas Sensor Platform with Bluetooth low-energy (BLE) is intended as a reference design that customers can use to develop end-products for consumer and industrial applications to monitor gases like carbon monoxide (CO), oxygen (O2), ammonia, fluorine, chlorine dioxide etc. BLE adds a wireless feature to the platform that enables seamless connectivity to an iPhone or an iPad. Customers can easily replace the targeted gas sensor based on their application, while keeping the same analog front-

end (AFE) and BLE design. The system runs on a CR2032 coin-cell battery. AFE from TI LMP91000 interfaces directly with the electrochemical cell. The LMP91000 interfaces with CC2541 which is a BLE system on a chip from TI. An iOS application running on an iPhone 4S and newer generations or an iPad 3 and newer generations lets customers interface with this reference platform. Customers can use and customize the iOS application, the hardware files and firmware source code of CC2541, which TI provides as an open source. The Gas Sensor Platform with BLE provides customers with a low-power, configurable AFE and the option to integrate wireless features in gas-sensing applications. This platform helps customers access the market faster and helps differentiate from performance, power, and feature sets. The platform complies with the below certifications on wireless:

EN 300 328 compliant FCC 15.247 compliant IC RSS-210 compliant The platform complies with the below certifications on EMC:

FCC FEDERAL COMMUNICATIONS COMMISSION Part 15, Class B EN 301 489-17 The heart of this reference platform is the AFE from TI, the LMP91000. The LMP91000 is perfect for use in micropower, electrochemical-sensing applications. The LMP91000 provides a complete signal-path solution between a sensor and a microcontroller that generates an output voltage proportional to the cell-

current. This device provides all of the functionality for detecting changes in gas concentration based on a delta current at the working electrode. The LMP91000 is programmed to support multiple electrochemical sensors, such as 3-lead toxic gas sensors (see Figure 1-4) and 2-lead galvanic cell sensors (see Figure 1-5) with a single design as opposed to multiple discrete solutions. The AFE supports gas sensitivities over a range of 0.5 to 9500 nA/ppm. It also allows for an easy conversion of current ranges from 5 to 750 A, full scale. The adjustable cell-bias and transimpedance amplifier (TIA) gain are programmed through the I2C interface. The I2C interface can also be used for sensor diagnostics. An integrated temperature sensor can be read by the user through the VOUT pin and used to provide additional signal correction in the C or monitored to verify temperature conditions at the sensor. The AFE is optimized for micropower applications, and operates over a voltage range of 2.7 to 5.25 V. The total current consumption can be less than 10 A. Additional power-saving capabilities are possible by switching off the TIA and shorting the reference electrode to the working electrode with an internal switch The LMP91000 supports many different toxic gases and sensors, and is configured to address the critical parameters of each gas.

Sensor Design 1.1.1 Fundamental Blocks of LMP91000:

Transimpedance Amplifier TIA provides an output voltage that is proportional to the cell current. TIA provides seven programmable internal-gain resistors and allows the external-gain resistor to connect to the LMP91000.

(Vref_div Vout) / (RTIA) = Iwe Vout = (Vref_div) (RTIA Iwe)

(1)

(2) Input The LMP91000 provides a 3-electrode solution counter electrode (CE), reference electrode

(RE), working electrode (WE) (see Figure 1-4), as well as a 2-electrode solution short the CE and RE (see Figure 1-5). Variable Bias Variable bias provides the amount of bias voltage required by a biased gas sensor between RE and WE. This bias voltage can be programmed to be 1% to 24% of the supply, or it can be VREF. The bias can also be negative or positive depending on the type of sensing element. Vref Divider This is the voltage at the noninverting pin at TIA. This voltage can be programmed to be either 20%, 50%, or 67% of the supply, or it can be VREF. The Vref Divider provides the best use of the full-scale input range of the analog-to-digital converter (ADC) and sufficient headroom for the counter electrode of the sensor to swing in case of sudden changes in the gas concentration. How to select the appropriate Vref divider:

If the current at pin WE (Iwe) is flowing into the TIA, then the Vref divider should be set to 67%

of Vref. If Iwe is flowing out of the TIA, then the Vref divider should be set to 20% of Vref. Assume Vref_divider is set to 20% of Vref. Assume Variable Bias is set to 2% of Vref. Assume Vref = 4.1V. The Vref divider in that case would be 0.82 V. The noninverting input to A1 woul;d be 0.902 V, which is 22% of Vref. SNOA922April 2013 Submit Documentation Feedback Copyright 2013, Texas Instruments Incorporated Gas Sensor Platform Reference Design User's Guide 7 Introduction www.ti.com Control Amplifier A1 A1 is a differential amplifier used to compare the potential between WE and RE. The error signal is amplified and applied to the CE. Changes in the impedance between the WE and RE cause a change in the voltage applied to CE in order to maintain the constant voltage between WE and RE. Temperature Sensor An on-board temperature sensor provides a 3C accuracy. The sensor can be used by an external C to correct for performance over temperature. Serial Interface Calibration and programming is done through the I2C digital interface. Calibration and state-of-health monitoring is enabled by the I2C interface. As mentioned before, health monitoring is very important because chemical cells can degrade over time. 1.1.2 Examples of Firmware and iOS Calculation This section explains the signal path and signal processing as implemented in the Gas Sensor Platform, from the sensor to LMP91000, to CC2541 and to the iOS application. 1.1.2.1 O2 Sensor Example The following example uses the O2 sensor from the Alphasense A2 series (see Section 1.3.1). A change in A current of the sensor indications a change in gas concentration. The LMP91000 processes the current and uses the linear TIA stage to convert the current to analog voltage (see Figure 1-1). The analog voltage is then sent to CC2541. The CC2541 then converts the raw analog voltage to a digital signal through a 12-bit ADC and transmits the signal through the Bluetooth radio to an iOS device. The iOS device then performs postprocessing. 1.1.2.1.1 Postprocessing Steps as Implemented in the iOS Covert voltage (binary to decimal). In this example, we assume that CC2541 transmits 0348h in its VOUT field. iOS software converts this hexadecimal voltage into a decimal value:

0348h = 840 Since the ADC is inside the CC2541 is a 12-bit resolution (2s complementary). Thus the ADC resolution inside CC2541:

2.5 V / (211-1) = 0.001221 Note: LM4120 provides a fixed 2.5V precision reference to both LMP91000 and CC2541 in this reference platform and thus we have used 2.5 V above to calculate the ADC resolution inside CC2541 . Multiply the decimal value from Equation 8 with the ADC resolution:

840 0.001221 = 1.025 V

(Vref_div Vout) / (RTIA) = Iwe_fresh air Vref_div here is 67% of Vref. RTIA above is set to 7000. Thus current at pin WE (Iwe) flowing into the TIA is ~91 A (fresh air calibration).

(6) To change the O2 concentration, if you exhale (breathe out) on the O2 sensor; the VOUT would increase. Let's assume that CC2541 transmits 03B0h in its VOUT field. 03B0h will translate to 944 in decimal. (see Equation 8). 944 0.001221 = 1.152 V Thus current at pin WE (Iwe) flowing into the TIA in this case would be: (1.667 1.152) / 7000 =

73.5 A In Equation 11, the calibrated fresh air WE (Iwe) value is 91 A. For calibration, this can be set to correspond - 20.9%. When we exhale (breathe out) on the O2 sensor; the normalized O2 percentage would then be:

(73.5 20.9) / 91 = 16.88%

(7) 8 Gas Sensor Platform Reference Design User's Guide Copyright 2013, Texas Instruments Incorporated SNOA922April 2013 Submit Documentation Feedback www.ti.com 1.2 CO Sensor Example CO Sensor Example The following example uses the CO sensor from the Alphasense CO-AF series (see Section 1.3.1). A change in A current of the sensor indications a change in gas concentration. The LMP91000 processes the current and uses the linear TIA stage to convert the current to analog voltage (see Figure 1-1). The analog voltage is then sent to CC2541. The CC2541 then converts the raw analog voltage to a digital signal through a 12-bit ADC and transmits the signal through the Bluetooth radio to an iOS device. The iOS device then performs postprocessing. 1.2.1 Postprocessing Steps as Implemented in the iOS Covert voltage (binary to decimal). In this example, we assume that CC2541 transmits 019Fh in its VOUT field. iOS software converts this hexadecimal voltage into a decimal value:

019Fh = 415 Since the ADC is inside the CC2541 is a 12-bit resolution (2s complementary). Thus the ADC resolution inside CC2541:

2.5 V / (211-1) = 0.001221 Note: LM4120 provides a fixed 2.5V precision reference to both LMP91000 and CC2541 in this reference platform and thus we have used 2.5 V above to calculate the ADC resolution inside CC2541 . Multiply the decimal value from Equation 8 with the ADC resolution:

415 0.001221 = 0.506 V

(Vref_div Vout) / (RTIA) = - Iwe_fresh air

(8)

(9)

(10) As Iwe is flowing out of the TIA in case of CO sensor, then the Vref divider should be set to 20% of Vref. RTIA above is set to 7000. Thus current at pin WE (Iwe) flowing out of the TIA is ~857nA (fresh air calibration).

(11) Based on the CO-AF specification, the sensitivity of the sensor is 55-90nA/ppm. In the iOS software, the sensitivity is set to 70nA/ppm (~average of the range). 857nA 70nA/ppm= ~12ppm Note: The RTIA for the CO-AF sensor is set to 7000. This ensures that the full range of the CO-AF sensor (0-5000ppm) can be utilized without clipping. 1.3 Supported Sensor Types The Gas Sensor Platform from TI can be used either with a 3-lead amperometric cell (not included) (see Figure 1-4) and a 2-lead galvanic cell (not included) in potentiostat configuration (see Figure 1-5) by a minor resistor change shown in Figure 5-4. For a 3-lead amperometric cell (CO), R43 must be un-installed. For a 2-lead galvanic cell (O2) R43 must be installed.

System Running With LED Flashing SNOA922April 2013 Submit Documentation Feedback Copyright 2013, Texas Instruments Incorporated Hardware Description 17 Battery Life Calculation 3.2 Battery Life Calculation www.ti.com For battery life calculations, it is highly recommended that the customer reviews CC2541 Battery Life Calculation, SWRA347. It is impossible to use a single metric to compare the power consumption of a BLE device to another device. For example, a device gets rated by its peak current. While the peak current plays a part in the total power consumption, a device running the BLE stack only consumes current at the peak level during transmission. Even in very high throughput systems, a BLE device is only transmitting for a small percentage of the total time that the device is connected (see Figure 3-4). Figure 3-4. Current Consumption In addition to transmitting, there are other factors to consider when calculating battery life. A BLE device can go through several other states, such as receiving, sleeping, and waking-up from sleep. Even if the current consumption of a device in each different state is known, there is not enough information to determine the total power consumed by the device. Each layer of the BLE stack requires a certain amount of processing to remain connected and to comply with the specifications of the protocol. The MCU takes time to perform this processing, and during this time, current is consumed by the device. In addition, some power might be consumed while the device switches between states (see Figure 3-5). All of this must be considered in order to get an accurate measurement of the total current consumed. Figure 3-5.

The increase resulted in a better return loss value of 10 dB. SNOA922April 2013 Submit Documentation Feedback Copyright 2013, Texas Instruments Incorporated Antenna Simulations 23 www.ti.com Summary of Findings 4.2 Summary of Findings The battery board does not significantly influence the antenna (see Table 4-1). Good omnidirectional radiation pattern is found. Low peak gain of 1.2. Antenna radiation efficiency is estimated at 54%. 4.3 Conclusion Overall board size is very small. Reduces the antenna efficiency from an estimated 70% to 54%. Influences the match of the antenna to become only 6 dB. By increasing the last inductor from 3 to 5 nH, the match is improved. 4.4 FCC Reports The Gas Sensor Platform is compliant with FCC and EU radiation requirements.

See http://www.iar.com/ for information on this platform. To communicate to the development platform through IAR, the CC Debugger is required. See Section 3.1. The CC Debugger must be connected to the 10-pin header on the SAT0010 board. Make sure that the notch on the cable that connects to the 10-pin header is facing away from the sensor or toward the outside. If connected properly, the LED on the CC Debugger should turn green.
