Version History Version 1.0 1.1 Date 22-04-2019 28-12-2020 1.3. Purpose Description Initial release Remove QR Code Update Specifications The purpose of this document is to guide users on how to use and deploy LoRaWAN Sense Nodes. 1.4. Scope This document will mainly focus on LoRaWAN Sense Node and its implementation as a Poultry and Livestock Data Monitoring device. 1.5. Definitions, Acronyms, and Abbreviation Term LoRaWAN LoRa Gateway TRH Sensor OTAA DevEUI AppEUI AppKey Description A MAC protocol for high capacity, long-range star network that the LoRa Alliance is standardizing for Low Power Wide Area Networks (LPWAN). Designed to be used in long-range star network architectures and are utilized in a LoRaWAN system. Also known as LoRa Concentrator. Temperature and Relative Humidity sensing component integrated into the LoRaWAN Sense Node. Over-the-Air activation method. Device EUI is the unique ID of the LoRaWAN sense node. Application EUI is the unique ID of the Application Server. The AppKey is the encryption key between the source of the message (behind the DevEUI) and the destination of the message (behind the AppEUI). UM0001 Version: 1.2 Create Date: 21 August 2019 Version Date: 19 June 2023 P a g e | 3 Sense Node User Manual 2. Product Description 2.1. General Description The PTS LoRaWAN Sense Node is a device that measures Temperature &

Relative Humidity and transmits the data to a Gateway through LoRaWAN Communication Protocol. This device can be paired with an existing LoRaWAN network. The device transmits the data measured from the TRH (Temperature and Relative Humidity) sensor at a fixed interval. This device will greatly help the users that need to remotely monitor the environmental conditions of their poultry sheds. 2.2. System Operation The entire system is composed of the following:

Hardware:

1. LoRaWAN Sense Node collects temperature measurement and transmits the data to the gateway periodically. 2. Gateway receives the data from LoRaWAN Sense Node. This gateway can receive data from any LoRaWAN enabled device. Software:

1. Network Server authenticates data received by the gateway. If data is addressed to Network Server, data is processed and will be forwarded to Application Server. 2. Application Server decrypts the data from Network Server. 3. Web Dashboard a visual representation of the data decrypted by the Application Server. Figure 1.

Standby Mode When the device is shipped, it will be on Sleep Mode. The power consumption at this mode will be minimal. At sleep mode, the device will not be measuring and transmitting temperature and relative humidity data. It is recommended to store the device in Standby Mode to prolong the battery lifespan. 3.2. Active Mode Before using the device, it should be switched to Active Mode first. During active mode, the device will be measuring and transmitting the temperature and relative humidity data periodically. There is an LED indicator in the device to show the following status:

Status Device Activated Join Request Procedure Success Data Transmission LED Blinking Pattern Fast Blinking 5x Fast Blinking 5x (after device activation) Blink 1x 3.3. Device Reset If a problem occurs (e.g. no data received from the device), the device can be reset by placing the magnet near the device again. The LED will blink 3 times indicating that the device is deactivated and will return to Standby Mode. Place the magnet near the activation point to activate the device again.

Payload Decoding The payload contains the temperature data from the sensor. It is encoded into hexadecimal format. The data length is 4 bytes. The first 2 bytes are for the temperature data. The last 2 bytes are for relative humidity. Below is an example of a payload decoder. function Decoder(payload) {

var decoded = {};

// Decode bytes to integer var temperatureInt = (payload [0] << 8) | payload [1];

var humidityInt = (payload [2] << 8) | payload [3];

// Decode integer to float decoded.temperature = temperatureInt / 100; // Temperature in C decoded.humidity = humidityInt / 10; // Humidity in %

return decoded;

In the example above, if payload = 099D02AB, the decoded value will be:

"humidity": 68.3,

"temperature": 24.61 UM0001 Version: 1.2 Create Date: 21 August 2019 Version Date: 19 June 2023 P a g e | 8 5. Deployment Procedure Sense Node User Manual When requesting for Sense Node only (no gateway and network server), the user/client should already have an existing LoRaWAN System on their site. The device is set to OTAA (Over-the-Air Activation) mode and it has pre-defined Device EUI (DevEUI), Application EUI (AppEUI), and Application Key (AppKey). NOTE: If the client requests for the sensor device only, it is assumed that they know how to add/register the device to their Network Server. 5.1. Check the Device Information PTS will provide the following information:

1. PTS Device Serial Number 2. DevEUI 3. AppEUI 4. AppKey 5.2. Register the Device to the Network Server Add/register the device into the network server using the keys provided in section 5.1. Use Over-the-Air Activation in registering the device. Example:

UM0001 Version: 1.2 Create Date: 21 August 2019 Version Date: 19 June 2023 P a g e | 9 5.3. Activate the Device Sense Node User Manual The device is shipped in Standby Mode to conserve battery power. Activation is done by placing a magnet near the marked part of the device. Please refer to section 2.3. When a magnet is first placed near the device activation point, it will activate the device. LED will blink 5 times to indicate device activation. The LED will blink again 5 times to indicate that the Join Request Procedure is done, and the device is ready to transmit measurement data. NOTE: When the Join Request Procedure is done, it will be connected to the Network Server through shared keys. Modifying the device registration in the Network Server will cause the device to be disconnected from the network because the shared keys will be void. Reset the device as instructed in section 5.5. Sometimes the Join Request Procedure fails. When this happens, the user has 2 options:

1. Wait for the device to automatically re-try the Join Request Procedure after 3 minutes. 2. Reset the device as described in section 5.5. 5.4. Check if the Device is Transmitting Here are the recommended ways to check if the device is transmitting:

1. Check in the Network Server if the payload is received from the device. 2. Check your dashboard if the temperature data is posted. 5.5. Reset the Device (optional) If the join procedure failed or no data is received from the device, the first option is to reset it. To reset the device, place the magnet near the activation point. The LED will blink 3 times to indicate that the device is deactivated. This means the device is in standby mode. Activate the device again by doing the activation procedure in section 5.3.
