Hello friends, I hope you all are doing great. Today, I am going to share the new CCS811 Air Quality Sensor Library for Proteus V1.0 . The CCS811 is the tiny digital gas sensor on the popular CJMCU-811 board that many indoor air quality projects use. It reports two numbers over I2C : TVOC , the total volatile organic compounds in the air, and eCO2 , an "equivalent CO2" that it estimates from them. Behind the part sits our own model , written from the datasheet and checked against the Adafruit CCS811 library , the one most makers use with this sensor - so the library's own calls get exactly the answers they expect. The sensor starts in boot mode and needs APP_START, measures in one of five drive modes , pulls nINT LOW when a result is ready, ignores the bus while nWAKE is HIGH, needs its ru ...
