Air quality sensing with MEMS based MiCS-VZ-86 or MiCS-VZ-89 module

Makes monitoring of air quality in the car, home, workplace or the environment hassle free

Pewatron launches 4 new intelligent air quality sensing modules. The MEMS based MiCS-VZ-86/89 air quality module makes the process of detecting VOCs simple by using innovative metal-oxide-semiconductor technology supported by a micro-electromechanical structure (MEMS). The sensing elements provide a swift response to changes in the levels of a wide range of VOCs and hence air quality. The technology has been produced in high volumes and to rigorous quality control for more than 10 years. The low power module incorporates an advanced signal processing algorithm to change the sensor signal into standard outputs. In addition, the proprietary algorithm automatically compensates small changes in sensor output over time and provides calibration free operation.

The modules come in 4 versions, which are combinations of output format and supply voltage format. Output format is I2C (MiCS-VZ-89) and PWM (MiCS-VZ-86), and for each of these the supply voltage can be chosen freely between 3.3 VDC (MiCS-VZ-89T/MiCS-VZ-86T) or 5 VDC (MiCS-VZ-89F/MiCS-VZ-86F)

Not only does the sensor produce an effective means of monitoring the level of VOCs in the air, it also provides an equivalency signal for the concentration of carbon dioxide - CO2 is commonly used as a proxy for air quality.

The sensing module is ideal for the following applications;

• Occupancy detection to reduce energy costs by the intelligent control of heating, ventilation and air conditioning systems

• Vehicle cabin air quality control

• Bathroom and kitchen fan control

• Air cleaners and purifiers
