ch4 sensor arduino

20170525· I have been using the sample code to read values from the sensor on Arduino Uno with a Grove Shield. While the code works I am not sure if the sensor is working or not. I know it is NOT accurate BUT the values reported are clearly crazy. For example some of the CH4 readings I am getting at my desk where I am experimenting with the sensor are:

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.

Another important category of sensors that you need to interface with ESP32 is analog sensors. There are many types of analog sensors, LDRs (Light Dependent Resistors), current and voltage sensors being popular examples. Now, if you are familiar with how analogRead works on any Arduino board, like Arduino Uno, then this chapter will be a cakewalk for you because ESP32 uses the same functions ...
