An Arduino Based Solar Water Heater Controller

Le Wed 01 March 2017

We were less than thrilled to find a power spike had gone through the house while we were away on holiday leaving our Solar Water Heater Controller's brains a bit addled. It was never a particularly good controller anyway and the suppliers are a pretty "prickly" bunch when it comes to trying to get information from them, so this was an opportunity to do what I had been meaning to do for a while. This article describes a home built solar water heater controller based on an Arduino. Now the set points are adjustable and able to be tuned to the local conditions. What more could you want in a solar water heater controller?

The Solar Water Heater Controller in a Perfect World

Le Wed 01 March 2017

This article describes the lovely rosy perfect world solar water heater controller project where we are untroubled with things such as non-perfect installation, the loveliness of quiet power supplies and things. Here you will find the circuits, coding, and associated project information. However don't get me wrong this is the perfect place to start making a real world system to suit any solar water heater controller situation.

A Simple Pressure and Temperature Logger

Le Tue 23 February 2016

This article describes a simple logger arrangement that measures pressure and temperature from two pressure sensors; a BMP180 barometer for when things go right, and an MS5803-14BA high pressure sensor for when things go wrong. This logger will be installed inside the ROV shell in place of the control electronics to record the internal pressure while the ROV is subjected to design pressures in a dive decompression chamber. This will show up if there are any leaks. If the pressure rises then there is a problem.

A Simple Arduino Based Logger

Le Tue 19 January 2016

This article describes a very simple Arduino based logger for capturing temperature data and recording it to a MicroSD card. It is intended as a building block for another logger project that will include pressure measurements for use during an in-air pressure test for the ROV project.

Three Arduino Circuits for Temperature Measurement

Le Tue 27 January 2015

So many ways to measure temperature with an arduino! Here is a brief investigation into using three different types of temperature sensor; Thermistors, DS18B20s, and TMP36s. This is with the intention of adding one of these to the ROV circuit so that I know when it has caught fire.
