Why Choose the Carlo Gavazzi CGESC02W2S CO2 Sensor?

The Carlo Gavazzi CGESC02W2S is a wall-mounted CO2 environmental sensor with switching output designed for carbon dioxide monitoring and demand-controlled ventilation in HVAC and building automation applications. As part of the Carlo Gavazzi CGES environmental sensor range, it combines infrared CO2 measurement with a configurable switching function in a compact room-mounted enclosure.

The CGESC02W2S measures carbon dioxide concentrations across a 0–2000 ppm working range. Its CO2 measurement is based on the infrared principle and incorporates automatic calibration technology designed to compensate for ageing of the infrared source, supporting dependable measurement and long-term stability.

Designed for straightforward wall installation, the CGESC02W2S provides a switching output with adjustable switching point and hysteresis, making it particularly suitable for controlling ventilation equipment according to measured indoor CO2 concentration. The sensor operates from a SELV 24 V AC ±20% or 15–35 V DC supply and is designed for integration into HVAC controllers, building management systems and indoor air-quality control applications.

Reliable CO2 Monitoring for Building Automation

Indoor carbon dioxide concentration is commonly used as an indicator of occupancy and ventilation requirements. By continuously monitoring CO2 levels, the Carlo Gavazzi CGESC02W2S allows ventilation systems to respond when concentrations reach a configured threshold, helping maintain suitable indoor conditions while avoiding unnecessary ventilation when demand is low.

The integrated switching output provides an adjustable switching point and hysteresis, allowing the sensor to control compatible ventilation equipment or provide a threshold signal to an HVAC controller or building management system. Infrared measurement with automatic calibration supports stable long-term operation in offices, classrooms and other occupied indoor environments.

Typical Applications

  • Demand-controlled ventilation systems.
  • HVAC and air-handling control.
  • Building management systems.
  • Office and commercial building CO2 monitoring.
  • Classrooms and educational facilities.
  • Meeting rooms and occupied public spaces.
  • Indoor air-quality and ventilation control systems.
