LoRa Climate Monitor

With this kit, you can measure temperature, humidity, luminosity and pressure. Then the values are sent wirelessly to the LoRa gateway.

You can use community The Things Network to receive the data.

What You Will Need

Firmware Upload

Step 1: Download the latest BigClown Playground

Step 2: Connect the Core Module to your computer.

Step 3: In Playground, go to the Firmware tab, select bcf-lora-climate-monitor and flash the firmware.

Step 4: After upload, the red LED on the Core Module will turn on for 2 seconds, then it will turn off.

LoRa Configuration

For configuring the LoRa keys please follow LoRa AT Commands Configuration tutorial.

Transmitting the data

The LoRa Climate Monitor sends a LoRa packet when:

  • After power-up, when the batteries are inserted

  • Every 15 minutes when the measure values are the same

  • After pressing the button

  • When you type AT$SEND to the console

Reading the Data

The data are encoded in the LoRa message. You need to extract the right bits to get the values back. This is explained in the README.md file. You can also use the decode.pypython script in the repository. In the same directory there is also decode.js which you can use in the TTN backend to decode values and send them for example directly to Ubidots.

You can pass the received HEX string as a parameter for the decode.py:

>>> python3 decode.py 011b0100f5600024c313
