estc5wam – temperature humidity & co2 5000ppm wall
Carlo Gavazzi ESTC5WAM is a wall-mounted temperature and NDIR CO2 transmitter with a 0–5000 ppm measuring range, 4–20 mA analogue output and RS485 Modbus communication for HVAC and building automation systems.
Why Choose the Carlo Gavazzi ESTC5WAM Temperature and CO2 Wall Sensor?
The Carlo Gavazzi ESTC5WAM is a wall-mounted environmental transmitter for temperature and carbon dioxide (CO2) measurement designed for building automation, HVAC control and indoor air quality monitoring. As part of the Carlo Gavazzi EST environmental sensor range, it combines temperature sensing with an NDIR CO2 measuring element in a compact enclosure for permanent room installation.
The ESTC5WAM measures carbon dioxide concentrations across a 0–5000 ppm CO2 range together with room temperature. It provides 4–20 mA analogue outputs for connection to controllers and building management systems, while integrated RS485 Modbus communication enables digital monitoring and integration into modern automation networks.
Designed for wall mounting, the sensor operates from an 8–35 V DC or 12–30 V AC supply. Its combination of analogue and Modbus connectivity makes it particularly useful for demand-controlled ventilation, indoor environmental monitoring and energy-efficient HVAC applications in commercial and industrial buildings.
