20/04/2018· MQ-6 Gas sensor can detect or measure gasses like LPG and butane. The MQ-6 sensor module comes with a Digital Pin which makes this sensor to operate even without a microcontroller and that comes in handy when you are only trying to detect one particular gas.
16/01/2020· The MQ135 air quality sensor will be a good assistant here as it can provide useful information about the surrounding air. The MQ-135 gas sensor is available as a prewired module or as just the gas sensor part alone. If you’re trying to detect the presence of a gas( not measuring PPM) only then you can buy a cheap module since it comes with onboard
Module comportant un capteur MQ135 permettant de détecter plusieurs types de gaz: le benzène (C6H6), l'ammoniaque (NH3), le sulfure, la fumée et la pollution atmosphérique. Ce module est compatible Arduino et Raspberry Pi (voir remarque) via une sortie analogique.

Curva de calibração do sistema desenvolvido no presente trabalho . FONTE: Dados da Pesquisa. 4 CONSIDERAÇÃO FINAIS . De acordo com os dados apresentados, o sistema de monitoramento desenvolvido no presente trabalho utilizando o sensor MQ-135 apresenta alto potencial de aplicabilidade na determinação da decomposição de MOS. Porém por se tratar de um sistema muito sensível e volátil,
01/07/2016· I am working on MQ135 Gas sensor for CO2 PPM. I refer Internet blogs, datasheet, internet codes and i apply in my coding. I also got result in PPM in range of 420 to 450. is it true or not? What is CO2 PPM in Air? Also it gives me reading in loop, it can not go beyond 450 PPM. I used this equation Rs=( ( * RL ) - ( RL * Vout ) ) / Vout, where Vout is ADC value & RL=10 ratio=Rs/R0, where R0 ...
19/04/2017· Interfacing of MQ135 Gas Sensor with Arduino: In today’s world, we encounter different scenario where we see different gasses being emitted in atmosphere such as home appliances like air conditioner and industrial chimneys. Monitoring of these gasses is very important with safety point of view. Gas Sensors are very helpful in accomplishing this task. Small nose like sensor spontaneously …
