HDC1080 CCS811 Carbon Monoxide CO2 VOCs Air Quality Numerical Gas Temperature Humidity Sensor Module

Product Features
This module integrates two sensor chips CCS811 and HDC1080 on one board. The measured values of the two sensors can be read separately by IIC communication. The HDC1080 is a low power, high precision, miniature digital temperature and humidity sensor chip.

The CCS811 is a low-power miniature gas digital sensor for air quality monitoring. A metal oxide (MOX) sensor is integrated to measure the total equivalent volatile organic compound eTVOCs and equivalent eCO2 content. A microcontroller MCU is integrated inside the chip.
The gas content value measured by CCS811 is self-corrected by reading the temperature and humidity value of the HDC1080 sensor and writing it to the CCS811 internal environment temperature and humidity correction register.
