May 06, 2020· Dezember 2020. MQ135 Sensors are usable as an air quality sensor for detecting a wide range of gases, including NH3, NOx, alcohol, benzene, smoke and CO2. For me, these sensors should be affordable by the price but also deliver acceptable measurements. That’s the reason I decided to test this MQ135 Sensor.
An analog air quality sensor (NOx, NH3, CO2) analogique. The MQ135 sensor can detect Carbon Dioxide (CO2) and many other compounds like alcohol, benzene, nitrogen oxide (NOx, Oxyde d'azote), Ammonia (NH3), smokes in the air. The concentrations in the air impact the analog ouputs voltage that can be read with a microcontroler.
MQ135 Semiconductor Sensor for Air Quality Control Sensitive material of MQ135 gas sensor is SnO 2, which with lower conductivity in clean air. When the target combustible gas exist, The sensor’s conductivity is more higher along with the gas concentration rising. Please use simple electrocircuit, Convert change of conductivity to correspond ...

An arduino library for the MQ135 especially made for CO2 measuring while taking into account temperature and humidity - giosullutrone/MQ135
May 01, 2017· The MQ series are cheap gas sensors. They are resistive electro-chemical sensors. These sensors have a heating element and a resistance that react to gases. Below a MQ135 sensor opened. Inside it looks like that.
Oct 30, 2019· According to need, you can display the CO2 levels on Serial Monitor or LCD. I made this article simple and easy to understand so that beginners can also understand. Before getting started you must know about MQ-135. MQ-135 is a gas sensor which is sensitive to CO2. The change in CO2 levels changes the resistance of sensor which results in the ...
MQ135 gas sensor has high sensitivity to ammonia gas, sulfide, benzene series steam, also can monitor smoke and other toxic gases well. It can detect kinds of toxic gases and is a kind of low-cost sensor for kinds of applications. Features It has good sensitivity to toxic gas in wide range, and has advantages such as long lifespan, low cost and ...
Jan 04, 2017· 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).
