piBeacon: 5- connect sonsors to the rPi

[kw123]

using the BLE temp sensor myBLUE for the pool.

this seems to work:

rpi zero wifi $ 10
sd card $ 5
myBlue temp sensor $20

Put the RPI in line of sight to the pool.
Submerge the my blue sensor 90% into the water. - 1 inch down down does not work. The signal gets absorbed in the water

I still have the old RFXcom pool thermometer and the delta temp is ~ 0.5F
