Product Introduction

The T6703 series CO2 module is a non-dispersive infrared (NDIR) CO2 sensor designed for applications where space is limited. It is primarily used to measure CO2 concentration in the air, enabling effective air quality improvement through fresh air control, increasing oxygen levels, and optimizing indoor oxygen content on demand to save energy. The sensor is factory calibrated and supports a maximum range of 5000 PPM.

Features

Low-cost CO2 gas sensor requiring no calibration in most applications
Built-in patented ABC Logic™ software for automatic self-calibration
Long operational life of up to 20 years
Flexible design for easy interface with various MCUs
Compact design with universal interface for easy product integration
Patented technology: US6526801, US6255653, US6410918, US6588250 (Patents Pending)

Applications

Indoor air quality monitoring
HVAC systems and fresh air control
Energy-saving ventilation systems
Smart home and building automation
