YJJ MiCS-VZ-89TE 125 MW VOC Concentration Sensor for Monitoring Range 400-2000 ppm and Refresh Output Frequency 1 Hz

Product Description:

MiCS-VZ-89TE operating power 125 MW exhaust emission VOC concentration sensor

Features:

The MiCS-VZ-89TE combines state-of-the-art MOS sensor technology with intelligent detection algorithms to monitor tVOCsand 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-ofownership.

Features • Calibration-free • Low power • Wide VOCs detection range • High sensitivity • High resistance to shocks and vibrations Functional specifications • Volatile Organic Compounds VOCs • Equivalent Carbon Dioxide CO2 (equiv)

Performance Detection Method Semiconductor gas sensor, detecting a wide range of VOCs Monitoring Range 400-2000 ppm equivalent CO2 0-1000 ppb isobutylene equivalent tVOCs PWM Output Pin 1 : TTL output 30Hz +/-1%, Range 5…95%, duty cycle 3.3V Use a pull-up resistance between Pin 1 and Pin 6 Pull-up value: typ. 10kOhms for 3.3V operation I2C Output Pin 2 and 4 : Pull-up of 4.7 kOhms on master SDA and SCL Response Time Equivalent to conventional NDIR-CO2 sensors < 5 seconds for tVOC Refresh Output Frequency 1 Hz
