Analog CH4 Gas Sensor (MQ4) – Myduino

SKU: MYPDFR163 Categories: Gas, Sensors. Description. Description. This is an Arduino CH4 gas sensor. It uses MQ4 probe which is able to detect natural gas, CH4. It is less sensitivity in detecting alcohol, cooking fumes, and cigarette smoke. The sensitivity can be adjusted by the potentiometer. The output is proportional to the density of gas.


Interfacing of MQ135 Gas Sensor with Arduino

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.
