Description Our Gas leakage detector using Arduino is very responsive and attractive also because we are using the OLED display to display the information of the system to the screen. as we are using the MQ 6 sensor here which is the gas reactive sensor. it has a coil that reacts to the gas and varies the data. whenever it senses LPG gas the value of the output of the sensor will start the change that you can see in the video as I am going to share with you. the sensor can give both output analog as well as digital. as we are working here for the accuracy because we can take the chance so we will use the analog one. analog is more precise than digital. so whenever the sensor comes in the contact with the gas it changes the value and sends it to the Arduino. Arduino processes the value and compares it with the given threshold value in the database. and if the condition gets true the alarm start and if the condition is not true the alarm will not start. we also added some characters into the OLED display which is interesting. so see the full video Gas leakage detector using Arduino given in the last portion of the post.
