Easy connectivity and data transfer

The S-C02/T sensor is equipped with a Modbus interface, which provides easy setup and integration into large process control and automation systems. Indeed, the sensors measurements can be read in real-time over RS485 local network via the Modbus RTU protocol with Master-slave approach. The S-C02/T acts as a slave, and it allows for building network of up to 15 slaves. Moreover, the data of S-C02/T is accessible via the Modbus register table (for more information please refer to the installation manual guide).

A smart, versatile device that ensures an accurate monitoring of indoor air quality

Its technologies ensure long-term stability and performance: The S-CO2/T Modbus is pre-calibrated to measure, in real time, indoor CO2 concentrations from 0 to 2 000 ppm. Thanks to its dual wavelength measurement technology, the S-CO2/T Modbus is an intelligent device which ensures optimum performance and reliability. It can be placed anywhere where there is occupancy. Moreover, its compact design allows easy installation.

The S-C02/T Modbus device, is equipped with a built-in temperature sensor, which can provide an additional information on indoor air temperature to control any systems like air conditioning etc...

The S-CO2/T Modbus is tested, validated, and documented. It is compatible with all types of installation and will last as long as the installation. The Aereco CO2 sensor uses the NDIR technology, a selective CO2 technology that ensures good indoor air quality assessment with auto-calibration.
