# Pool Pump Controller

> Pool Pump Controller with arduino ethernet.

Original author: chris (source: https://www.achille.com/wp/pool-pump-controller/)

## Components

- **Arduino Ethernet Shield** x 1 ([docs](https://docs.arduino.cc/retired/shields/arduino-ethernet-shield-without-poe-module))
- **Seeed Studio Grove - 4-Channel SPDT Relay** x 1 ([docs](http://wiki.seeedstudio.com/Grove-4-Channel_SPDT_Relay/))

## Article

**Overview**
Time to get rid of that old analog timer, and to replace it with a new digital device, one that can be controlled remotely and can be queried at any time.

New Pool Controller: Arduino and Relay Module

**Components**

As sometime who tinkers from time to time, I just happened to have everything I needed on hand to make this a reality. The key were the following 2 components:

- [Arduino Ethernet](https://store.arduino.cc/usa/arduino-ethernet-rev3-without-poe) – This became the new controller, and a lot more advanced then the old timer.

- [SainSmart 4 Channel 5V Relay Module](https://www.sainsmart.com/products/2-4-8-channel-5v-relay-module) – This relay module is used to replace the timer mechanical system.

By putting these 2 together, we get exactly what we want. A remotely controllable switch to turn the pump on and off.
