Thermokon LK-IAQ CO2 VOC Temp rH Air Quality Duct 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.
The maintenance-free and multi-functional duct air quality sensor measures CO2, mixed gas (VOC), temperature and humidity (relative, absolute, enthalpy, dew point). Optional features, such as a relay output for a 2-point controller or a 2-stage 2-point controller, LCD and traffic light function allow for a wide range of applications. Depending on the model, the sensor can be configured individually via Thermokon USEapp. A hinged cover and tool-free wiring as well as removable cable entries ensure a quick and easy installation. Different Duct Sensors are available.
The LK-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.
