Automatic Stove Control System Based on the NodeMCU ESP8266 Microcontroller

Abstract

A stove is a handy tool for humans. The use of stoves in everyday life brings beneficial and detrimental impacts. A stove is a tool used to help human activities, but the impact of its weakness can cause household accidents caused by the negligence of the community itself. The NodeMCU-based automatic hob was built to address this problem. This stove can set the cooking time and automatically stop working at the specified time. This stove can also turn off automatically if the sensor does not detect the presence of people around to minimize the occurrence of household accidents. This automatic stove is expected to be a technological reformer in household appliances and a solution to reduce the number of accidents caused by stoves.

“…Relays use electromagnetic principles to move the switch contacts so that with a small electric current (low power) can deliver higher voltage electricity. For example, with a relay that uses 5V and 50 mA electromagnets able to move the relay armature (which functions as a switch) to deliver 220V 2A electricity [8].…”
