CDM4161A is a highly miniaturized pre-calibrated CO2 unit which uses Figaro's own compact and 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. 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.
