Abstract:
1. An apparatus for measuring humidity or moisture, comprising: a sensor module comprising a humidity or moisture sensor in electrical communication with a first set of terminals; and a hand-held reader module comprising a controller in electrical communication with a second set of terminals that are mateable with the first set of terminals such that the hand-held reader module is electrically connectable to and electrically disconnectable from the sensor module, the hand-held reader module being configured to read humidity or moisture data from the sensor in response to making electrical connection with the sensor module; wherein the first set of terminals comprises plural connector pins and the second set of terminals comprise plural landing pads, and wherein the plural connector pins and the plural landing pads make a same electrical connection regardless of the rotational orientation of the hand-held reader relative to the sensor module; and wherein the landing pads include multiple concentric rings, and the connector pins include multiple redundant pin pairs, such that each of the redundant pin pairs makes electrical contact with one of the concentric rings, wherein each of the redundant pin pairs includes two pins that are electrically coupled together and to the controller.
