Wireless Arduino Temperature Sensor Module

NOTE There is now an improved version of this available here and a post on my blog here.

 

This is the stripboard layout for my wireless temperature sensor module.

 

The RFM12B is fitted to a small carrier board because I only have a 5V FTDI cable for programming and as the RFM12B isn't 5V tolerant it needs to be removed during programming. It also has the benefit of allowing the final board to be smaller as the space under the RFM12B can be used while still keeping everything neat. Hat tip to Andrew Lindsay for the idea of mounting RFM12Bs like this.

 

More about this on my blog here.

 

NOTE: As pointed out by @netcompsys I've missed a track cut out on this diagram, the track from the data pin (blue wire) of the DS18BS20 should be cut under the 4K7 Resistor.
