· The MQ135 is one type of gas sensor that can sense NH3, NOx, alcohol, Benzene, smoke, CO2, and some other gases, these gases are harmful to human health. Arduino is the main microcontroller board of this system. The gas sensor continuously measures air quality and sends data to the Arduino board. Then Arduino prints air quality value on the ...
The MQ135 Gas sensors are used in air quality control systems and are suitable for detecting gases such as CO2, Smoke, NH3, NOx, Alcohol, Benzene, etc. The purpose of this tutorial is to explain how to develop a device which can monitor the pollutant parameters in Air, especially CO2 in real time using MQ135 Gas Sensor with ESP32 WiFi module to send the data to AskSensors IoT platform.
· Tutorial sensores de gas MQ2, MQ3, MQ7 y MQ135 Deja un ... Sensor de gas combustible y humo MQ-2. Estos sensores son adecuados para detectar GLP, propano, metano, alcohol, hidrógeno, humo. Siendo más sensible al GLP y propano. Sensor de Alcohol MQ3. Es muy sensible al alcohol y de menor sensibilidad a la bencina, también es sensible a gases como GLP, …
· MQ-135 gas sensor applies SnO2 which has a higher resistance in the clear air as a gas-sensing material. When there is an increase in polluting gases, the resistance of the gas sensor decreases along with that. To measure PPM using MQ-135 sensor we need to look into the (Rs/Ro) v/s PPM graph taken from the MQ135 datasheet.
· MQ135 not suitable for CO2. I think that I will stop my attempts for using the MQ-135 as a CO2 meter. With 1 sensor I measured different voltages on the analog port with same amount of CO2. It probably is to responsive to other gases in my surroundings. (Airport and highway).
