Common Questions APP can't find the device 1. If the phone Bluetooth is off, please turn on the Bluetooth and reconnect it;

2. Press the device button, if the blue light flashes, the device is normal. If the red light flashes or no response, it means device is out of power, please recharge and reconnect the device. 3. If the device has power and Bluetooth of the mobile phone is turned on, confirmed that the device is connected to other mobile phone in the vicinity, then you need to disconnect and reconnect the new mobile phone. Real-time monitoring data is not accurate:

1. The device monitors the weak body signals for analysis and calculation, ensuring that the sensor is below the chest heart position and there is no other interference. Wind and floor vibrations can affect signal acquisition.

- 9 -

Sleep data is always in sync:

1. If the sleep record is not synchronized for a long time, the synchronization process will last for a long time, and the data need to be synchronized for about 0.5 minutes per day. Please be patient. If the synchronization is not completed in 10 minutes, please exit APP and reconnect the synchronization. Can you use more than one person at the same time?

1. The product only monitors one person's movements, multi-person monitoring requires one device for each user. People around you while keeping a distance of 50cm does not cause excessive deviations and effects on sleep analysis.

- 10 -

Precautions 1. Special attention: Do not over-bend the product. The product has a built-in sensor. Excessive bending may damage the sensor. The reliability bend radius is 4cm. 2. Do not touch the product with high temperature equipment more than 60 C. Do not use it with electric blankets. 3. Do not throw the product into the water, which may cause damage to the inside of the product. 4. When the power adapter is plugged into a power outlet, do not touch the metal end of the power adapter. 5. The sensor is used on a flat, stable surface. Do not place the sensor strip on a moving bed (such as a hammock), which can cause the sensor belt to

not function properly. 6. Make sure that there are no sources of vibration close to ensure that the sensor belt can accurately detect the user's sleep, vibration caused by electric fans, washing machines, loud music, etc. may cause the product to be misjudged. 7. The sensor is no powered and will not cause any damage to the user. 8. The surface of the sensor belt is waterproofed, but it cannot be washed or soaked. The wet cloth can be twisted to the driest and gently wiped off in the dirty area of the sensor belt. 9. If the product is not used for a long time, the sensor can be rolled up and stored at a safe radius. It is forbidden to fold the sensor tape and compress it for storage, which may cause damage to the product.

Small Size 2.4GHz PCB Antenna-AN043 1 DATASHEET KEYWORDS The PCB antenna Description Antenna Name : AN043 Model Number : AN043 Maximum Gain : 2dBi Antenna Type : PCB Antenna Operation Frequency : 2400~2500MHz The Manufacturer Information Manufacturer Name : Espressif Systems Manufacturer Address:

#101, Block 2, 690 Bibo Road, Zhang Jiang HiJiangShanghai, China 2 TEST INTRODUCTION The PCB antenna described in this application note is now used on ESP8266 module reference design. However,it can also be used in all 2.4 GHz designs, especially small space is required for the antenna. Figure 1: ESP8266 Module 2.1 Layout and Implementation Small changes of the antenna dimensions may have large impact on the performance. Therefore it is strongly recommended to make an exact copy of the reference design to achieve optimum performance. It is also recommended to use the same thickness and type of PCB material as used in the reference design. Figure 2: Antenna Dimensions L1 L2 L3 L4 L5 L6 W1 W2 D1 D2 D3 D4 D5 D6 3.94 2.70 5.00 2.64 2.00 4.90 0.90 0.50 0.50 0.30 0.30 0.50 1 .40 1 .70 Table 1: Antenna Dimensions (Unit: mm) 4 TEST RESULTS Reflection, radiation pattern were measured to verify the performance of the PCB antenna. 4.1 Reflection All the reflection measurements were performed with a network analyzer connected to a semi-

rigid coax cable, which was soldered to the feed point of the antenna. Because of the small size antenna and the small ground plane this kind of measurements is heavily affected by the presence and placement of the coax cable. This influence can result in a small uncertainty in resonance frequency and measured reflection. Typically different placement of the semi-rigid coax cable could change the resonance frequency with 5 -10 MHz and the reflection with 3 - 4 dB. Figure 3 : Influence of Plastic Encapsulation and Test Pins The size of the ground plane affects the performance of the PCB antenna.Soldering ESP8266 to a test board increases the size of the ground plane and thus the performance is affected. However, bandwidth still can be enough to cover the whole 2.4GHz ISM band. 4.2 Radiation Pattern The radiation pattern for the antenna implemented on the ESP8266 reference design has been measured in an Lab chamber. Figure 4 through Figure 7 shows maximum value radiation patterns for three planes, XY, XZ and YZ, measured with vertical and horizontal polarization from 2400MHz~2500MHz frequency range. All measurements were performed with 0dBm output power. Figure 4: How to Relate the Antenna to the Radiation Patterns Figure 5:AN043 XY Plane Figure 6: AN043 XZ Plane Figure 7: AN043 YZ Plane 4.3 Maximum Gain The following table lists the Maximum Gain of the antenna. The free line of sight (LOS) range was measured with 250 kbps and 1% PER. Maximum Gain LOS range Antenna Size 2.0 dBi 240 m 15.2 x 5.7 mm
