This is the ENS160 a digital multi-gas sensor solution developed by ScioSens, this sensor is suitable to be used for Air Quality to detect and sense a chemical around in the environment, and suitable also to be used in building automation, smart homes, HVAC / Ventilation System / Smart Thermostats / Air Purification / Appliances / Kitchen Cooker Hoods / Mobiles / Wearables / Smart Things & IoT Devices. This sensor independently controls that allows the detection of VOC  (volatile organic compounds) including ethanol, toluene, hydrogen, and oxidizing gasses with an advanced detection sensitivity.

The ENS160 enables intelligent algorithms to process raw sensor data detected on the chip. However, these algorithms calculate the CO2, TVOC  air quality indicates the Air Quality Information and perform a humidity and temperature compensation including baseline management. Additionally, raw sensor measurements can be read for further customization according to your needs. The ENS160 consists of 4 major independent sensing feature a heater and a gas sensor element based on metal oxide technology.
