ESP32 Arduino: Temperature, humidity and CO2 concentration ...

May 05, 2018· ESP32 Arduino: Temperature, humidity and CO2 concentration web server. In this ESP32 tutorial we will check how to develop a HTTP web server that will expose an API for clients to retrieve measurements of temperature, humidity and CO2, using a CO2 sensor and a DHT22 temperature and humidity sensor. The tests were performed using a DFRobot’s ...


Solved: BME680 on ESP8266 IAQ, CO2, ... do not change

Nov 21, 2020· Re: BME680 on ESP8266 IAQ, CO2, ... do not change I have exactly the same problem as Desh: This is the output of the Basic example "" with my ESP32 Board: Temperature, pressure, humidity and gas values give reasonable readings, but IAQ, Static IAQ, CO2 equivalent and breath VOC equivalent never change!


Air Quality with MQ135 and Wemos D1 mini ESP8266 Rob''s blog

Jan 17, 2017· Measure Air quality with MQ135 and ESP8266 Wemos D1 mini. As the MQ135 is not really suited as a CO2 sensor (See my previous blog) and I still wanted to use it, I will use it as an air quality probe on an the title mentioned I will use an ESP8266 connected to my local WiFi router for this to send the data to The ESP8266 I use is the Wemos D1 mini.
