Solar Hot Water Temperature Monitoring with Arduino + ThingSpeak

Posted by Hans Scharler,

Here’s another “Klink Family Adventure”. The Klink’s created a solar water heater monitor using an Arduino connected to multiple waterproof DS18B20 temperature sensors. What’s great about this project is that it has the complete schematic and source code for interfacing multiple sensors to ThingSpeak at the same time. This is a common request in the ThingSpeak forum, so we are glad to see the code in the wild. The application is great. Monitoring the yield of a solar water heating system allows you to keep track of efficiency and savings.

Here’s what the temperature looks like now in Australia:

Check out the family’s blog for the source code and to learn how to create your own solar water heater monitoring system.
