Data Sheet MiCS-VZ-89TE The MiCS-VZ-89TE is an integrated sensor board for Indoor Air Quality monitoring. 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. Features Calibration-free Low power Conversion from PWM output signal of MICS-VZ-89TE to Wide VOCs detection range equivalent Carbon Dioxide concentration in ppm High sensitivity High resistance to shocks and vibrations Detectable gases Volatile Organic Compounds VOCs Equivalent Carbon Dioxide CO (equiv) 2 Conversion from PWM output signal of MICS-VZ-89TE to equivalent tVOC concentration in ppb For more information please contact: Info.em sgxsensortech.com SGX Sensortech, Courtils 1 CH-2035 Corcelles-Cormondrche Switzerland Comparison between MICS-VZ-89TE output signal and NDIR www.sgxsensortech.com CO2 sensor signal over a duration of 4 consecutive days (Thu Sun) Page 1 of 5MiCS-VZ-89TE Data Sheet Performance Detection Method Semiconductor gas sensor, detecting a wide range of VOCs 400-2000 ppm equivalent CO2 Monitoring Range 0-1000 ppb isobutylene equivalent tVOCs Pin 1 : TTL output 30Hz +/-1%, Range 595%, duty cycle 3.3V PWM Output 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 Equivalent to conventional NDIR-CO2 sensors Response Time < 5 seconds for tVOC Refresh Output Frequency 1 Hz Operation Supply Voltage 3.3V DC regulated +/- 5% Operating Power 125 mW Warm-up Time 15 min Operating Temperature 0C to 50C Operating Humidity 0%RH to 95%RH (non condensing) Storage Temperature -40C to 80C Storage Humidity 0%RH to 95%RH (non condensing) IMPORTANT PRECAUTIONS Read the following instructions carefully before using the indoor air quality sensor described in this document to avoid erroneous readings and to prevent the device from permanent damage. The sensor must not be exposed to high concentrations of organic solvents, ammonia, silicone vapour or cigarette-smoke in order to avoid poisoning the sensitive layer. The sensor should be protected against water and dust projections. SGX strongly recommends using ESD protection equipment to handle the sensor.
