# Energy Monitor and SMS notification

> Energy Monitor

Original author: oyashi (source: https://www.youtube.com/watch?v=VkJ1YUo2Lic&t=98s)

## Components

- **Arduino Ethernet Shield** x 1 ([docs](https://docs.arduino.cc/retired/shields/arduino-ethernet-shield-without-poe-module))
- **Arduino UNO** x 1 ([docs](https://www.farnell.com/datasheets/1682209.pdf))

This project is monitoring UPS

I simply drew this project in blocks.

current is measured by CT sensor and Voltage is measured by UNO but voltage is too high so he used stepdown transformer.

The sending SMS is different depending on the code sent to the GMS shield

also this system can receive and transmit SMS through SIM900(arduino GDM module)
