Automatic And Smartphone Controlled Digital Gas Stove With Smart IoT Features

Gas stove is a common kitchen appliance that carries a high level of risk. This paper focuses on limiting kitchen hazards and reducing unnecessary gas burns by developing an automatic and smartphone-controlled gas stove. This project is based on an ATmega328p microcontroller, embedded in an Arduino Uno R3 that collects data from a MQ-4 gas sensor, an IR sensor, and a NTC thermistor. The microcontroller works with a defined code and follows specific conditions. It processes the data and issues commands according to the conditions. Following the commands from the Arduino, a servo motor controls the gas flow to the stove. A NodeMCU module is connected to an Arduino Uno for serial communication. The data from the MQ-4 gas sensor is sent to the smartphone via this module. Blynk app is used to monitor and control the gas flow to the stove by positioning the servo motor.
