Low-Cost LPG Leakage Detector and Refilling Alert System

LPG gas cylinder is a necessary thing in everyday life of human being as it is used for everyday cooking purpose. So, for this availability of LPG gas at every moment is very much compulsory. Now it is a huge problem that every one of us has faced, that is at any moment the LPG gas comes to an end but people get notified when the LPG gas is already exhausted. Also, in this time of corona wave, a huge number of corona patients need oxygen gas cylinder and, in this case, also we have to be alert about completion of the gas. So, for these reasons, we have taken an initiative so that people can get notified before the completion of the gas and can book gas cylinders as early as possible. So, in our proposed system there will be a weighing machine on which the LPG gas cylinder will be kept and after a certain weight the machine will send a message through the GSM module to the mobile number that will be registered in the GSM module of the machine and people can get aware of the completion of the gas and can book gas cylinder at that moment. In this way, the problem can be solved.
