Netvox RA0716 Wireless PM2.5/Temperature/Humidity Sensor

Principles of operation

Netvox RA0716 has a built-in air temperature and humidity sensor and dust sensor. The air temperature and humidity sensor SHT-30 communicates with the module through I2C, and the dust sensor communicates with the LoRa module through the UART serial port. It reports the PM2.5, temperature, and humidity data periodically.
