Wireless SO2 Sensor
The R718PA6 is a wireless communication device that detects SO2 concentration in ambient air. The main unit and SO2 sensor communicate via the RS485 connection interface, and it sends detected data to the other equipment via wireless network compliance LoRaTM wireless communication protocol standards.
