ABSTRACT:
A remote passive condition sensor apparatus such as a temperature or humidity sensor apparatus. A corner cube reflector at a remote location, where it is not feasible to have electrical connections or batteries, receives and reflects back radiant energy to an optical readout instrument. Condition responsive elements in the corner reflector affect the amount of reflected radiant energy as a function of the condition sensed.
