Have you ever wondered how good air quality is in your living room? Or do you need proof of why you fall asleep in an unventilated meeting room after 3 hours? Look no further! This combo board of this air quality sensor gives you the answers in the shortest time!This Air Quality Combo Board feels the atmospheric quality with the popular CCS811 and BME280 ICs. It offers a variety of environmental data, including barometric pressure, humidity, temperature, TVOCs and equivalent CO2 (or ECO2). Communication is possible via the I2C protocol.The CCS811 is an extremely popular sensor that provides readings for equivalent CO2 (or ECO2) in parts per million (PPM) and total volatile organic compounds in parts per billion (PPB). The CCS811 also has a function that allows you to adjust its readings when it has access to the current humidity and temperature. That's why we added the BME280, which provides humidity, temperature and air pressure. This allows the sensors to work together to give us more accurate readings than they can offer themselves.Since the CCS811 warms up a bit, the PCB is precisely designed to not affect the BME280 sensor readings.This text is machine translated.
