Product Overview
The MiCS-VZ-89TE is an integrated sensor board designed for Indoor Air Quality (IAQ) monitoring. It leverages state-of-the-art MOS sensor technology and intelligent detection algorithms to monitor total Volatile Organic Compounds (tVOCs) and Carbon Dioxide equivalent (CO2eq) variations in confined spaces such as meeting rooms and vehicle cabins. The dual signal output (PWM and I2C) enables on-demand ventilation control, leading to energy savings and reduced cost of ownership. This sensor is calibration-free, offers low power consumption, a wide VOC detection range, high sensitivity, and robust resistance to shocks and vibrations.
