This fully integrated detection module is a NDIR dual channel sensor device for measuring carbon dioxide. Our NDIR sensors, complemented by off the shelf and customized RF remote control and transmitter solutions respectively, are used to measure indoor air quality as well as for characterizing confitions in many industrial processes. By intense technological developments, our NDIR sensor modules are able to measure even in high humidity environments, while keeping traditional characteristics of user friendly control interface. The high quality sensor with its accurate CO2 concentration measurent capabilities allows the robust integration in application specific controller implementations based on the CO2 level as one key process indicator, as for complex air-conditioning and ventilation requirements e.g. in agriculture industries.
