PRODUCT INFORMATION
CDM4161 - Pre-calibrated module for carbon dioxide
Features:
Applications:
* High selectivity to CO2
* Maintenance free
* Low power consumption
* Long life
* Compact size
* Pre-calibrated
* Low cost
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.

Note 1: Assumes benchmark is set accurately at 400ppm of CO2. This value
does not contain long term drift.
Note 2: Inthis module, the CO2 conentration 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).
