The device uses LoRaWAN to uplink temperature, humidity and precipitation sensor data through calculation. Data will be sent every 6 minutes, if there is rain, the sending time will be 1 minute Support sensors:
- USB to UART Converter
- RainGauge board
- Arduino IDE (version v1.8.13 or above is recommended)
- RUI3 lastest firmware for RAK3172: RAK3172-E_latest_final.hex
- (STM32CubeProgammer)[https://www.st.com/en/development-tools/stm32cubeprog.html]
- Adafruit_SHTC3.h
On the RainGauge board
- Hold the B_RAK (boot) button and press R_RAK (reset) button and release the B_RAK (boot) button to enter bootmode.
- Select UART, Baudrate 115200 and press Connect.
- Open RAK3172-E_latest_final.hex
- Select the address as in following image if needed
- Press Download to upload firmwave
- After download success, press R_RAK (reset) button to exit the bootmode

- Go to Tool -> Board -> Boards Manager, search & install RAKwireless RUI STM32 Boards
- Open
ATC_Command_RF210.inosketch, seletc WisDou RAK3172-T Board from Tool menu - Plug in your board and upload
- Select Tool -> Board -> RAKwireless RUI STM32 Modules -> WisDuo RAK3172 Evaluation Board
- Depends on your country region and how you set up your gateway. Please create the correct application with it to be able to receive data
- In Danang, Vietnam we use the AS923_2 band and eu1.cloud.thethings.network
- You need to create application for RainGauge Board
- Select end device -> Register end device to create your device
- After creating the device, now you just need to copy Device address, NwkSKey, AppSKey and paste it into your code.
- The data sent will be in the default format
- You can change the format of the data to be able to observe changes
-
The average energy consumption when the device is operating (sending data to the server) is 8.36mA for ~15s.
