PRODUCT INFORMATION

CDM7162-C00 - Pre-calibrated CO2 ModuleFeatures:

Applications:* Small size
* Low power* High accuracy* Single light source, dual wavelengthsystem* Indoor air quality control* Fresh air ventilators* Air conditioners* Automatic fans and window openers* Safety measures for lithium-ion batteries

The CDM7162* CO2 module uses a compact NDIR CO2sensor, featuring excellent performance characteristics,
including high accuracy and low power consumption.
Stable long term operation and output are achieved by dual
IR detectors and Figaro's proprietary signal processing
technology.
Every module is individually calibrated and is provided
with both a UART and I2C digital interface. The CDM7162
module is designed for simple integration into a user'sproducts. It can be used in a wide range of applications
such as ventilation controls for the improvement of energy
savings and to assure a good indoor climate.
