IMPLEMENTATION OF CONTROL AND MONITORING OF ELECTRIC CURRENT PROTECTION SYSTEM IN NODE-RED

BASED CABLE EXTENSION AS AN effort TO PREVENT FIRE

Unwise use of electrical energy in households can cause energy waste and

increase the risk of hazards, such as short circuits hat have the potential

to cause fires. Based on data from the Ministry of Energy and Mineral

Resources , households account for around 48.38% of the total electricity

usage in Indonesia. Therefore, a protection system is needed hat is able

to monitor current and power in real-time and automatically disconnect

the current when overload occurs, especially on frequently used extension

pr roll cables, This research develops a Node-Red-based electric currens

protection system using ESP8266 microcontroller, and PZEM 004-T

sensor _to detect voltage, curent, and power. The system is remotely

ontrolled and integrated with a Wi-Fi network

Tests were conducted individually and combined on household evices

such as laptop chargers, fans, and solderers, The test results show that the

ystem can accurately monitor current and power, and maintain electrical stability when the load is below the safe limit, When the load

exceeds the set limit, the system automatically cuts offthe electricity to

prevent the risk of fire. This implementation is expected to improve the

safety of electricity use in households and become a reference for further

development in Internet of Things (loT)-based protection systems.
