Types Of Sensor That Being Used For Experiment

       Before we are using MQ-4 for this project we run some experiment to some sensor to determine which sensor is more suitable for our project and for ours circuit

This is the first sensor that we used for the experiment which is MQ-137

 

This is the second sensor that we are using that is MQ-2

The third sensor that we used is MQ-138

The last sensor that we being use is MQ-4

After getting the result we decide to used MQ-4 for ours project.This is because the LPG Gas Sensor (MQ4), ideal sensor for use to detect the presence of a dangerous Liquefied petroleum gas (LPG) and it has high sensitivity to propane, butane, isobutene, natural gas. The sensor can also be used to detect combustible gases, especially methane. This sensor has a high sensitivity and fast response time.
