How to monitor air quality CO2 using ESP32 and CCS811

The CCS811 sensor is a gas sensor that is able to detect several compounds in the air. It can measure the equivalent CO2 present in the air and the total volatile organic compounds named VOCs. These are a class of compounds that are considered pollutants and sensory irritants. They are produced by a variety of sources including people’s breath.

ESP32 and CCS811 gas sensor data to Thingspeak example ...

The CCS811 is a low-power digital gas sensor solution, which integrates a gas sensor solution for detecting low levels of VOCs typically found indoors, with a microcontroller unit (MCU) and an Analog-to-Digital converter to monitor the local environment and provide an indication of the indoor air quality via an equivalent CO2 or TVOC output over a standard I2C digital interface.

Measure CO2 & TVOC using CCS811 Gas Sensor & Arduino

· Overview. In this tutorial, we will interface CO2 & TVOC Gas Sensor CCS811 with Arduino & measure CO2 & TVOC in the air. The CCS811 Air Quality Breakout Board is a digital gas sensor capable of sensing a wide range of Total Volatile Organic Compounds (TVOC) & equivalent carbon dioxide (eCO2) with metal oxide (MOX) levels. We can thus use this sensor to identify the air quality …
