Research, Share, Explain

We are investigating durable, cost effective and accurate sensors appropriate for placing within a beehive. Please document any temperature sensor research below.

I did some tests with DS18B20 sensors, the positive side is you can use it in a 1-wire-topology, this is optimal e.g. for measuring between combs. It seems also that there are large (and for beekeeper) more than sufficient meshs possible, see http://www.maximintegrated.com/en/app-notes/index.mvp/id/148

The downside is the relatively long reading time (and so power consumption). But there are some techniques to avoid this. In case you use an Arduino, first send a command to calculate new data, in the time waiting time conversion takes place sent arduino to sleep and wake it up to read the temp.
