Hioto (Home IoT Automation) System for Gas Monitoring and Safety System for Remote Surveillance and Control via Blynk App

LPG gas is one of the basic needs of households in everyday life. However, LPG gas is flammable. Many accidents occur due to gas leaks. The most common trigger is direct contact between the leaking gas and the nearest power source. Therefore, this study aims to identify gas leaks and alert people, helping to reduce the incidence of house fires due to gas leaks and electrical short circuits. Gas leaks from cylinders are detected using the MQ135 gas sensor. Measurements of electric voltage and electric current flowing in the house are detected using the PZEM004T voltage and current sensor. It connects to the ESP32, which is set to send messages via the cloud directly to the user's smartphone. This type of research is qualitative and quantitative, with data collection techniques through literature studies and experiments. The analysis used is descriptive analysis with an empirical approach. This IoT project will automatically cut off the house's electricity if a gas leak is detected and the use of electric current is not reasonable under the conditions specified in the program. Users can monitor the use of electricity, gas levels in the area, and the surrounding conditions through the ESP32CAM camera. This innovation has the potential to continue to be developed to create a smart home security system with more features.
