Integration of Surilli WiFi with MQ135 Webserver -

Jun 13, 2019· MQ135 Sensor. The MQ135 Sensor Module consists of a steel exoskeleton under which a sensing element is housed. This sensing element is subjected to current through connecting leads. This current is known as heating current through it, the gases coming close to the sensing element get ionized and are absorbed by the sensing element.

ATMEGA32 and MQ135 to calculate Air Quality | AVR Freaks

Dec 09, 2020· Unfortunately most of my googling leads to people using MQ135 with Arduino boards, Ive yet to find anyone using ATMEGA32. I am using an old phone charger to supply power 5v , I do not have any resistors installed between power supply and ATMEGA32, only a capacitor. MQ135 does have an on board variable resistor (which I have not touched).

MQ-135 Gas Sensor Pinout, Features, Alternatives ...

Feb 27, 2018· 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 …
