GENERAL DESCRIPTION
CCS801 Ultra-Low Power Analog VOC Sensor for Indoor Air Quality Monitoring ams micro-hotplate technology provides a unique silicon platform for the CCS80x range of Metal Oxide (MOX) gas sensors. These devices enable sensor miniaturization, have ultra-low power consumption and provide fast response times due to the ability to heat the micro-hotplate very quickly.The micro-hotplates are fabricated using a robust silicon dioxide membrane and include an embedded tungsten heating element to heat the MOX based sensing material. The MOX sensing material can be heated up to 500°C to allow the electrical resistance of the MOX sensor to be monitored to detect the target gas. By exploiting the fast heater cycling times, temperature modulation techniques can be used to reduce the device power consumption and implement advanced gas sensing methods. Software libraries containing proprietary algorithms and example Android applications are available for indoor air quality monitoring.
