CDM4161 - Pre-calibrated module for carbon dioxide

CDM4161 is a new unit which uses TGS4161, Figaro's low-power consumption solid electrolyte CO2 sensor. Due to Figaro's proprietary idea for signal processing with a microcomputer, no maintenance is required for this module. By application of DC voltage to the module, an analog output voltage proportional to CO2 concentration can be obtained.

The module can generate a control signal based on a user-selectable threshold concentration. When compared with traditional CO2 sensor modules using IR sensors, Figaro's CO2 module is much more cost effective, making this module the ideal choice for indoor air quality control systems.

* CO2 monitors

Note 1: Assumes benchmark is set accurately at 400ppm of CO2 . This value does not contain long term drift.

Note 2: In this module, the CO2 concentration is calculated by measuring the relative change of sensor output at the measuring point from sensor output in clean air (assumed to be 400ppm of CO2 ).
