Smart sensor and RTU 2-in-1 LoRaWAN terminal from the Polysense iEdge 4.0 line. Four gases on one terminal: CO, H2S, O2 and CH4. It monitors carbon monoxide, hydrogen sulfide, oxygen and methane from one terminal and reports the readings over a LoRaWAN network. The OD outputs can switch external devices such as relays, beepers or fans when a reading or a remote command triggers them.
