Why Choose the Carlo Gavazzi SHSUCOTHL CO2, Temperature & Humidity Sensor with Traffic Light?
The Carlo Gavazzi SHSUCOTHL is a Smart Dupline room sensor for CO2, temperature and relative humidity monitoring, featuring an integrated RGB traffic-light indicator for clear visual indication of indoor carbon-dioxide levels. Designed for wall-mounted building automation applications, it combines three environmental measurements in one compact sensor to support ventilation, HVAC and indoor air-quality control.
The SHSUCOTHL measures CO2 from 0–2000 ppm using non-dispersive infrared (NDIR) dual-source technology. It also measures temperature from -20 to +50 °C and relative humidity from 0–100% RH, providing comprehensive room-condition data to a compatible Smart Dupline building-control system.
A key feature of the SHSUCOTHL is its integrated RGB LED traffic-light indication. CO2 thresholds can be configured through the Smart Dupline system so that the LED automatically changes between green, yellow and red according to the measured CO2 concentration, giving occupants an immediate visual indication of room air quality.

Clear Traffic-Light Indication for Indoor Air Quality
The Carlo Gavazzi SHSUCOTHL provides both building-control data and an immediate visual indication of CO2 conditions. Using the Smart Dupline configuration tools, thresholds can be defined for transitions from green to yellow and from yellow to red. The integrated RGB LED then changes colour automatically according to the measured CO2 level, allowing occupants to recognise changing ventilation requirements at a glance.
Combining this visual indication with temperature and humidity measurements makes the SHSUCOTHL particularly useful for demand-controlled ventilation and intelligent HVAC applications. Because the unit is powered and communicates through the Dupline 2-wire bus, several sensors can be connected to the same bus, helping simplify wiring in multi-room building automation installations.
Typical Applications
- Indoor air-quality and CO2 monitoring.
- Demand-controlled ventilation systems.
- HVAC and climate-control automation.
- Office and meeting-room monitoring.
- Classrooms and educational buildings.
- Commercial and public buildings.
- Occupancy-related ventilation control.
- Temperature and humidity monitoring.
- Smart building energy-management systems.
