Amphenol T6703-5K Air Quality Monitoring CO2 Sensor

规格

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
