CCS801

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. Product Overview CCS801 is an ultra-low power analog sensor for monitoring indoor air quality including Carbon Monoxide (CO) and a wide range of Volatile Organic Compounds (VOCs) such as Ethanol. CCS801 can be used as an equivalent carbon dioxide (eCO2) sensor to represent eCO2 levels in real world environments, where the main source of VOCs is from humans. For CCS801 a supply voltage (VH) is provided to the integrated micro-heater and the gas concentration can be correlated to the change in...
