Third and Final sensor installed

This morning I stopped off at Maplins to get more cable( yellow just for a change) so I could install the third floor sensor. The sensor is outside the lifts on the second floor.

I'm getting a signal from the sensor but I am getting odd strange new messages now and again - not sure why.

I now have a full array of floor sensors and a good back log of data. 

Sensor 1 will have to be moved, and I think sensor 3 is a bit odd.
