The CCS811 air quality and gas sensor is a highly accurate and reliable sensor module designed to measure the levels of various volatile organic compounds (VOCs) and other gases in the air. It is commonly used in applications such as indoor air quality monitoring, smart homes, and wearable devices.
The CCS811 sensor is based on a metal-oxide gas sensor technology, and can detect a wide range of gases, including carbon monoxide (CO), nitrogen dioxide (NO2), and various organic compounds such as ethanol, benzene, and formaldehyde. It features a built-in algorithm to compensate for changes in temperature and humidity, which can affect the accuracy of gas measurements.
The CCS811 sensor communicates with a microcontroller using an I2C interface, and provides real-time gas readings in parts per billion (ppb). It also includes a digital output pin that can be used to trigger an interrupt when the gas readings exceed a certain threshold.
