Esp32 Wroom and CCS811 in deep sleep - ESP32 Forum

2018-04-05· Im extending my project and added a CCS811 air quality sensor and need some suggestions from anybody using it in its project. I put rhe board in deep sleep for 1 minute after all readings. The problem is that this IC needs 20 minutes to stabilize every time its initialized(if i understood it properly) so after every esp32 wake it reinitializes the i2c and CCS811 needa another 29 minutes to ...

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.

CCS811 driver for ESP-IDF (ESP32) - GitHub

2020-12-17· Initiating 2nd I2C bus on ESP32 with CCS811 sensor. I want to connect two CCS811 sensors with ESP32 dev board. Since the sensors have fixed address, I am unable to use them simultaneously. I have read that on ESP32 multiple I2C buses can be created. While trying to follow that route I tried to modify the library but I am stuck.
