ardiff

This is an Arduino project for controlling a water pump for a solar water heater. Includes:

  • controller: Arduino 1.x sketch for the controller
  • arlog.py: A simple Python script for monitoring the Arduino's serial output

Circuit

To make effective use of this controller, you'll need circuits for your temperature sensors and for the pump relay. Some example circuits made using Qucs are provided in the schematics directory.

Requirements

Because the temperature sensors need to be at the end of longish wires, this controller uses the DS18B20 temperature sensors, which require the OneWire and DallasTemperature libraries. Download and extract those, and put them in your ~/sketchbook/libraries folder before using this controller.
