Wireless H2S (Hydrogen Sulfide) Sensor


The WLRC-S52 is a wireless sensor that detects Hydrogen Sulfide (H2S) concentration in air. The body and the Hydrogen Sulfide 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.
