TUYA IoT Smart Gas Knob

MQ135 gas senso r The MQ135 Gas sensor can detect gases like Ammonia (NH3), sulfur (S), Benzene (C6H6), CO2, and other harmful gases and smoke. Similar to other MQ series gas sensors, this sensor also has a digital and analog output pin. When the level of these gases goes beyond a threshold limit in the air, the digital pin goes high. This threshold value can be set by using the onboard ...


Arduino CO Monitor Using MQ7 Sensor : 8 Steps (with ...

PNP transistor won''t work with a mentioned Flying Fish module (because it has heater pin soldered to sensor''s output), but can be used with a discrete MQ7 sensor. 3. Resistors: 2 x 1k (from to will work fine), and 1 x 10k (that one is best kept precise although if you absolutely must use a different value, adjust reference_resistor_kOhm variable in the sketch accordingly).


Air pollution Project Project Guidance Arduino Forum

20210505· For example: 1 CO with MQ 309 A 2 O3 with MQ 131 3 NO2 with MICS2714 4 SO2 with MQ 136 5 C6H6 with Grove HCHO sensor. Those sensors are typical for each element so I think it should work but I wanted your opinion just in case you have tried before :) Thank you! jurs December 2, 2015, 11:41am 16. Klajdi: Thank you but the idea of this project is to make itself not to buy a gadget . …
