Why Choose the Carlo Gavazzi SHSUCOTD CO2 & Temperature Sensor with Display?
The Carlo Gavazzi SHSUCOTD is a Smart Dupline CO2 and temperature sensor with integrated LCD display, designed for indoor air-quality monitoring and intelligent building automation. The wall-mounted sensor continuously measures carbon dioxide concentration and ambient temperature, providing valuable environmental data to a compatible Smart Dupline control system.
The SHSUCOTD uses Non-Dispersive Infrared (NDIR) technology with an E+E dual-source infrared sensing system to measure CO2 concentrations from 0 to 2000 ppm. CO2 accuracy is specified at better than ±(50 ppm + 2% of the measured value) under reference conditions, while the integrated temperature sensor measures from -20 to +50 °C with an accuracy of ±0.5 °C.
An integrated LCD display with LED backlight allows measured values to be viewed directly at the installation point. The front touch button activates the backlight and allows the displayed signal type to be changed. The SHSUCOTD is powered directly from the Dupline bus, requiring only the bus connection for power and communication and helping simplify installation in Smart Dupline building automation systems.

CO2 and Temperature Monitoring for Better Building Control
Carbon dioxide concentration is an important indicator of indoor air quality in occupied spaces. As people occupy a room, CO2 levels can rise if ventilation is insufficient. By continuously measuring concentrations from 0 to 2000 ppm, the SHSUCOTD can provide Smart Dupline systems with information that can be used as part of demand-controlled ventilation and building-management strategies.
The integrated temperature sensor adds room-temperature information to the same device, allowing both environmental parameters to be incorporated into building automation logic. Local values can also be viewed directly on the LCD display, while the front touch button activates the backlight and allows the user to change which measured signal is displayed.
Typical Applications
- Indoor air-quality monitoring.
- Demand-controlled ventilation systems.
- Smart home and building automation.
- Office and workplace environmental monitoring.
- Meeting rooms and conference facilities.
- Schools, classrooms and educational buildings.
- Residential temperature and CO2 monitoring.
- HVAC and ventilation control applications.
- Smart Dupline building automation installations.
