Telaire VOC Sensor Module


Telaire VOC Sensor Module

Telaire MiCS-VZ-89TE Integrated Sensor Board

The MiCS-VZ-89TE combines state-of-the-art MOS sensor technology with intelligent detection algorithms to monitor tVOCs and CO2 equivalent variations in confined spaces, e.g. meeting rooms or vehicle cabins.

The dual signal output can be used to control ventilation on-demand, saving energy and reducing cost-of-ownership.

Important Precautions:

- The sensor must not be exposed to high concentrations of organic solvents, ammonia, silicone vapor or cigarette-smoke in order to avoid poisoning the sensitive layer.

- The sensor should be protected against water and dust projections.

- Telaire strongly recommends using ESD protection equipment to handle the sensor.
