Abstract

Although power control of single-phase loads is already widely used, conventional solutions present limitations, such as the lack of monitoring of electrical quantities and integration with other systems. In this context, this work proposes a solution based on microcontrollers from the ESP family, capable of controlling load power through triac firing angle control, measuring voltage and current, and integrating with Wi-Fi networks using the MQTT protocol, enabling information exchange and the sending of alerts via Node-RED and Telegram when improper electrical values are detected.
