This document describes a project to monitor and control a substation using a microcontroller and IoT. Sensors are used to measure current, voltage, temperature and frequency. The microcontroller collects and stores the readings in a MySQL database. A WiFi module is used to transmit the data remotely so it can be accessed anywhere. Relays and buzzers are used to provide alerts in case of abnormal readings to ensure safety of the system. The goal is to allow real-time remote monitoring without human dependence to prevent failures in the distribution grid.
