CDR-MOD Modbus CO2 sensors are designed to detect CO2 (carbon dioxide) concentration and temperature in the room spaces and have built-in Modbus RTU RS485 communication interface. The devices are addresses via bit switch or via the network. The Modbus CO2 sensor calibrates automatically its measurement using statistical analysis. The Modbus CO2 sensors have programmable linear 0..10V signals outputs. The CDR-MOD Modbus CO2 sensors have also a built-in digital and a resistive input (e.g. for external temperature measurement), and two additional digital outputs as standard.

The CDR-MOD Modbus CO2 sensors can be installed on wall surface or on a wall mounting box in dry indoor environment. The CDR Modbus sensors come with a number of additional options such as display, active setpoint, occupancy detection, lux level measurement, push button and additional digital and resistive inputs.

The CDR-MOD Modbus CO2 sensors can also operate as CO2, temperature, humidity or light level controllers modulating analogue outputs, or switching the digital output on based on the setpoints making them ideal for advanced control applications.
