CO2 sensors with visual and audible alert

Too high CO2 concentrations? Sentera CO2 sensors are now available with audible alert. On top of that, the green, yellow and red LED offer a clear, visual indication of the CO2 level. The supply voltage is 230 V or 24 V.
CO2 sensors with visual and audible alert

Sentera CO2 sensors are now available with audible alert. The green, yellow and red LED offer a clear, visual indication of the CO2 level. When the CO2 level exceeds the alert value, the yellow LED and the buzzer are activated. When the CO2 level exceeds the maximum range value, the red LED and the buzzer are activated. 

These CO2 sensors can be flush-mounted or installed against a wall indoors. The supply voltage is 230 V or 24 V.

They measure temperature, relative humidity, CO2 and ambient light level. The sensor algorithm controls the output based on the measured values. This output can be used to directly control an EC fan, an AC fan speed controller or a damper actuator. All measurements and the output value are also available via Modbus RTU. In many applications, the ambient light sensor can be used to control the ventilation system in function of the occupancy of the room.
