Solar Hot Water temperature monitoring with Arduino

One of the more popular Arduino-based projects is measuring and collating various forms of external data, and Rick has done just that by building a system that monitors the temperature of his solar hot water as well as the external temperature. This data is then sent to the ThingSpeak Internet service to allow the data to be monitored from other places, for example:

Although the project sounds complex, it is quite simple and Rick has documented it well including schematics and Arduino code. From a hardware perspective, you need an Ethernet-enabled Arduino and the best solution for this is our Freetronics EtherTen - the Arduino-compatible board with Ethernet, microSD card and optional PoE support:

To measure the temperature the project uses DS18B20 1-wire temperature sensors, and these are easily implemented using one of our sensor modules, the TEMP:
