ModBus sensor measuring temperature, CO2 and humidity and transmit the measurement to control unit as ModBus signals.
CO2 – Temp – Humidity Sensor Modbus uses the widely used ABC algorithm, which ensures long life without calibration. Only the room cannot be used constantly, but must regularly get sufficient airflow to lower the CO2 to fresh air level.
Note: A new version of this sensor is available from November 2025. Please check whether the product name includes M25 or not. The products function identically; the only difference between the M25 and the previous model is the selection of the Node ID for Modbus.
