Wireless Nitrogen Oxides (NO2) Sensor


The WLRC-S53 is a wireless sensor that detects Nitrogen Oxides (NO2) concentration in ambient air. The body and the Nitrogen Oxides 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.
