CCS803 Ultra-Low Power Gas Sensor for Ethanol Detection ams micro-hotplate technology provides a unique silicon platform for the CCS80x range of Metal Oxide MOX gas sensors. These devices enable sensor miniaturisation, 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 an example Android app for Alcohol breathalyser use case are available. Product Overview The CCS803 is an ultra-low power MOX gas sensor for Ethanol detection. For CCS803 a supply voltage VH is provided to the integrated micro-heater and the gas concentration can be correlated to the change in resistance of the MOX sensing layer RS . VH can be set using a low-dropout LDO regulator or operated in pulsed PWM mode to reduce power consumption. The sensor resistance RS is typically determined using a series load resistor RL , a reference voltage VREF , and an output voltage VOUT read by an Analogue-to-Digital Converter ADC . The reference voltage VREF must only be enabled during the sensor reading. CCS803 is supported in a compact 2mm x 3mm x 1mm DFN Dual Flat No lead package as standard.
