This document describes a power monitoring system that measures and logs the power consumption of electrical devices. The system uses a current sensor to measure current, which is sent to an Arduino microcontroller. The Arduino calculates power consumption based on current and voltage. Data on power usage is sent wirelessly to a database on ThingSpeak using an ESP8266 WiFi module. The system allows setting timers to automatically turn devices off after a certain time period. This helps save energy. The system was tested on various loads and accurately measured and logged their power usage over time to the ThingSpeak database.
