Wireless Sulfur Dioxide (SO2) Sensor


The WLRC-S54 is a wireless sensor that detects Sulfur Dioxide (SO2) concentration in ambient air. The body and the Sulfur Dioxide sensor are connected through the RS485 interface, and the detected data is transmitted to other devices through the wireless network. The data transmission is based on the LoRa™ communication platform.
