keyestudio CCS811 Carbon Dioxide - Temperature Air Quality Sensor

Keyestudio CCS811 carbon dioxide, air quality sensor mainly uses the CCS811 chip. It is an ultra-low-power miniature digital gas sensor that can detect a wide range of volatile organic compounds (TVOCs), including equivalent carbon dioxide (eCO2) and metal oxide (MOX) levels. Equivalent carbon dioxide (eCO2) is measured in the range of 400 to 29206 ppm (parts per million), and various volatile organic compounds (TVOC) ranges from 0 to 32768ppb(parts per billion). 3mm diameter position hole on sensor contributes to fix on the other device. PINOUTS GND ground VCC Input power（5V） SDA I2C data pin SCL I2C clock pin RST Reset pin: connect to ground, sensor will automatically reset. WAKE WAKE pin should connect to ground to communicate with sensor conveniently INT This is the interrupt output pin that detects when a new reading is ready or the reading becomes too high or too low.
