Abstract

Safety plays a major role in today’s world and it is necessary that good safety systems are to be implemented in places of education and work. This work modifies the existing safety model installed in industries and this system also be used in homes and business premises. One of the preventive measures to avoid the danger associated with gas leakage is to install a gas leakage detector at vulnerable locations. “Gas Detector for Safety Home using GSM” is a project that is use to detect a gas leakage from the gas storage (cylinder gas) to the cooking stove and it also detect the unattended cooking that are left without supervision. In this project the gas sensor are used to detect the gas leakage and PIR Motion Sensor and Temperature Sensor are used in this project to detect unattended cooking that are left without supervision. This project will send an alert to the user about unattended cooking that are left without supervision and detection of gas leakage through GSM Module where the number of user are set in the GSM Module by SMS. This project used Microcontroller (Arduino UNO R3) at the processor where it process the input from the sensor and send the output to shut-off valve to cut the gas supply and to GSM module to communicate with the user (send an alert through SMS). This project will detect the gas leakage and unattended cooking by detecting the gas leakage that occur in the kitchen through the MQ-2 Gas Sensor and detect the unattended cooking by DHT 11 temperature and PIR motion sensor. In this project, the analysis is done by measuring the distance of the sensitivity of the PIR sensor to detect the motion. The higher the motion near to the PIR sensor, the higher the sensitivity of these sensor. The benefit of these projects is to prevent the earlier stage of fire because of unattended cooking without a human supervision, could prevent the explosion because of gas leakage and prevent a gas poisoning.
