Opencircuit Air quality, CO2, temperature and humidity sensor - CCS811 HDC1080

This module combines 2 powerful chips to measure the air quality, humidity and temperature in an environment. This makes the module a compact solution for projects where the quality of the air in a room must be monitored. The module works with 3.3V and communicates via I2C. The module uses only 100nA in sleep mode!

The CCS811 is a digital sensor with metal oxide (MOX) gas sensor to measure "Volatile Organic Compounds" (VOCs). The sensor can also measure "equivalent CO2" (eCO2).

The HDC1080 is a digital humidity sensor with integrated temperature sensor that offers excellent measurement accuracy at very low power. The HDC1080 works over a wide supply voltage. The humidity and temperature sensors are calibrated at the factory.
