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.

How to monitor air quality CO2 using ESP32 and CCS811

ESP32. This tutorial covers how to monitor indoor air quality using ESP32 and CCS811. In more detail, we want to monitor the air quality using two parameters: eCO2 = equivalent Carbon dioxide. tVoC = total volatile organic compounds. We will measure them using the CCS811 sensor with the ESP32. Moreover, we will show the result using a color LCD ...

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; Note that the CCS811 requires a supply voltage of .. So, is ok, but do not use a 5V board. The Nano has a "3v3 out" pin, but that's only a power out pin, the micro drives the I2C lines on 5V. This poses a risk to the CCS811. Also note that the minimum supply voltage of the CCS811 is and should not drop below this value for reliable device operation. Most micro ...
