Videotrons on toll roads serve as visual information media to convey traffic conditions, safety warnings, and early warnings to road users. However, the reliability of videotrons is greatly influenced by the stability of the electricity supply and the health of the devices. Electrical disturbances such as unstable voltage, power outages, overheating, and high humidity can cause device damage and disrupt videotron operations. This study aims to design and build an Internet of Things (IoT)-based electrical and videotron device health monitoring system on the Semarang–Solo Toll Road of PT Trans Marga Jateng. The system uses a NodeMCU ESP8266 as the main microcontroller integrated with a PZEM-004T sensor for monitoring electrical parameters and a DHT22 sensor for monitoring temperature and humidity. Data is sent in real-time via the internet to the Blynk & Telegram application as a monitoring and early notification medium. This study uses a Research and Development (R&D) method with a prototype model. The results show that the system is capable of monitoring voltage, current, power, electrical energy, temperature, and humidity in real-time and providing early notification when anomalies occur in certain parameters. This system is expected to improve the operational reliability of videotrons, speed up the handling of disturbances, and reduce device maintenance costs.
