Thermokon LA-IAQ CO2 VOC Temp rH Air Quality Sensor with LoRaWAN® ModBus Transceiver Option. The Thermokon Transmitters and Sensors are available with different interfaces like BACnet MS/TP, 4-20 mA or ModBus RTU. Contact us for the different versions.
Air quality sensor for measuring CO2, mixed gas (VOC), optionally temperature and humidity outdoors and in areas requiring high IP protection class (e.g. underground stations, tunnels, exhibition halls, cold chains and greenhouses as well as in production halls and warehouses). Default values can be indiviudally adjusted via Thermokon USEapp. For devices with CO2 and VOC, every output can be configured to be a mixed output (selectable ratio between CO2 and VOC). Devices with a relay option can be used as 2-point controllers or 2-stage controllers.
The LA-IAQ CO2 VOC Temp rH is communicating via ModBus RTU. The connected IQnexus LoRa® ModBus Transceiver is reading the ModBus Registers as a master and packs the register data into LoRaWAN® payloads.
