Solved: BME680 without VOC and CO2 data

Mar 19, 2019 · BME680 without VOC and CO2 data. Hello , I'm in your forum, because I have problems with your BME680. I need datas temperature,humidity, pressure, IAQ and voc/co2. The mainly problem are the data VOC and CO2. The datas are always zero. I use mainly your example bsec code plus WLAN and MQTT code for my esp8266. I use the BSEC lib v1.4.7.2.

Now I have 1043 ppm CO2 on the bme680 and 743 ppm on the MH-Z19. The VOC shows 9.8 ppm, a plausible value. So use the bme680 for rough estimates only. The voc seems KK. air pressure, humidity and temperature are very stable on the bme680 but the offset of the temperature is 3.8°C!

Guide for MQ-2 Gas Sensor with Arduino | Random Nerd Tutorials

May 05, 2016 · The MQ-2 gas smoke sensor is an analog sensor. It outputs a voltage between 0 and 5V accordingly to the gas concentration in the atmosphere. The greater the gas concentration, the greater the output voltage. The lower the gas concentration, the lower the output voltage. When the Arduino reads analog values, it returns 1023 when it reads 5V, and ...
