Carlo Gavazzi CGESC02W5S is a wall-mounted CO2 environmental sensor with a 0–5000 ppm measuring range and switching output for HVAC, ventilation and building automation applications.
The Carlo Gavazzi CGESC02W5S is a reliable wall-mounted CO₂ environmental sensor with switching output designed for monitoring carbon dioxide concentrations in building automation, HVAC and environmental control applications. As part of the Carlo Gavazzi CGES environmental sensor series, it provides dependable air-quality monitoring with a CO₂ measuring range of up to 5000 ppm.
Designed for indoor wall mounting, the CGESC02W5S continuously monitors carbon dioxide levels and provides a switching output that can be integrated with ventilation, air-conditioning and building control equipment. This enables automatic control strategies based on measured indoor CO₂ concentration, helping maintain suitable air quality while avoiding unnecessary ventilation.
The sensor operates from 24 V AC ±20% or 15–35 V DC and features a compact housing measuring approximately 85 × 100 × 26 mm. Screw-terminal connections and an M16 cable entry simplify integration into building automation and environmental monitoring installations.
Carbon dioxide concentration is an important indicator of indoor air quality and occupancy levels. CO₂ sensors allow ventilation systems to respond to changing conditions rather than operating continuously at maximum airflow, supporting effective demand-controlled ventilation and efficient building operation.
The Carlo Gavazzi CGESC02W5S combines a 5000 ppm measurement range with a switching output, allowing it to interface with ventilation controllers, relays and building automation equipment. Its compact wall-mounted format makes it particularly suitable for monitoring occupied indoor spaces and other controlled environments.
