Final Assembly

Some would say that at this stage I was almost there with the soil sensor project. All there was left to do was get the thing into the ground. Being that I am a flawed perfectionist, I had some other ideas . I was not going to simply chuck it in the ground without some more prevarication.

Anyway, onwards…

Reviving the Project

A very brief part three of the, somewhat delayed, soil temperature monitoring project. This project has been left a little on the side gathering dust whilst I spent some time concentrating on the cloud detection project, but I am now determined to get this system up and running and its sensors in the ground before the winter weather sets in. Being in the ground soon will also mean that I get a good run before the cold weather hits.

At this point I have progressed with getting the electronics from breadboard to circuit board, well, Veroboard anyway. Also, the mission has crept slightly: after some more research, I have decided that the project is to become more of a surface/ground temperature station with the addition of minimum grass and concrete temperature measurements.

Part two on the soil temperature monitoring project. Detailing some thoughts on how to get the sensors in to the ground in a way that will keep them protected from the underground environment. Following that, some subequent details on the construction of the sensor housings.

The Whys and Wherefores of Soil Temperature

This project has its roots in a chance sighting of some, what I thought were, interesting looking API parameters on the Met Office weather data submission service. I’ve been running a small weather station for about a year with its data output being harvested by a RaspberryPi and packed off to the Met Office observation service.

Many months ago a friend and I were idly browsing to see what other interesting data people were collecting and sending there when we spotted, to our surprise, soil temperature measurements using sensors buried at 10, 30 and 100 centimetres. These depths are certainly not arbitrary; they may represent three of the many soil horizons: A, B and C (See the Wikipedia page regarding soil horizons). This sparked off a thoughts on the possibilities of home made sensing, gathering and aggregating soil temperature readings to a service on the internet.
