There is a common factor in every example cited in this thread -- the 
link between sensor and readout is UHF RADIO, and the sensor has no 
external wires to act as antennas. If the designer has done a decent job 
with layout of the printed circuit board so that it does not contain 
antennas, there's nothing to act as an RX antenna for our transmitted 
signals, and nothing to act as a TX antenna for noise.

When there is RFI to or from equipment, it is nearly always the improper 
termination of the shields of external wiring that radiates trash and 
receives RFI. This mechanism was first identified by hams working in pro 
audio, and is known as The Pin One Problem.
