## Description

The SparkFun ENS160 Indoor Air Quality Sensor is a digital multi-gas sensor solution with four sensor elements that can be used in a wide range of applications including building automation, smart home, and HVAC. The independent hotplate control allows the detection of volatile organic compounds (VOCs) including ethanol, toluene, hydrogen, and oxidizing gases with superior sensitivity. The ENS160 supports intelligent algorithms to process raw sensor measurements on-chip. These algorithms calculate CO2-equivalents, TVOC, air quality indices (AQIs), and perform humidity and temperature compensation, as well as baseline management, all on-chip. Raw sensor measurements can be read for further customization.The ENS160 from ScioSense is a digital multi-gas sensor consisting of four independent heaters and gas sensor elements based on metal oxide (MOX) technology and a controller. TrueVOC® air quality detection provides outputs such as eCO2, TVOC, and AQI in compliance with worldwide IAQ standards.Along with the plug-and-play Qwiic connectors, both I2C and SPI functionality have been broken out to 0.1"-spaced pins in case you prefer to use a breadboard. Note: The default I2C address of the ENS160 is 0x53 and is jumper selectable to 0x52. The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
