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.
· CCS811 performance in terms of resistance levels and sensitivities will change during early life use. The change in resistance is greatest over the first 48 hours of operation. amsadvises customers to run CCS811 for 48 hours in the selected mode of operation to ensure sensor performance is stable
Acquire data using ESP32, CCS811 and Edge Impulse. The first step is acquiring data using ESP32 and CCS811: we will acquire CO2 concentration and tVoC (volatile organic compounds). This data will be forwarded to Edge Impulse. Before building this project is necessary to create an Edge Impulse account for free and a new project. Upload this code to the ESP32: # include <> # include ...
