20200705· As clearly pointed in this post, while using the “MQ135” librarysupported Arduino setup, the gas sensor calibration can be done at by finding the value of Ro in fresh air, and then using that value to find Rs through the formula: Rs = (Vcc/VRL1)x RL, that means Rs = (5V/(sensorValue * (/))1)*RL. I tried to make this primer very readable and self explaining and provided lots of ...

While the Arduino''s 5V power is theoretically able to power the K30, the sensor needs 300mA minimum to operate the light inside the sensor. The problem is, if you power the Arduino from your PC''s USB port, the K30 has to share power with the Arduino, your mouse, and any other devices on the USB bus. The power to the sensor will drop under 300mA, and it won''t operate properly.

20201218· In today’s tutorial, we are going to understand How to interface the MQ2 Gas sensor With Arduino Uno. MQ2 Gas Sensor Module. MQ2 gas sensor is basically an electronic chemiresistor, a sensing material whose resistance changes when it comes in contact with a gas. It is a sensor used for sensing the concentration of gases in the air such as LPG, propane, methane, hydrogen, alcohol, …
