A wireless switch is provided having a twenty-year life energy harvesting arrangement for self-powering a wireless transmitter. The energy harvesting arrangement is implemented in one embodiment using a piezoelectric switch element. A tritium light source and photovoltaic device are used in a second embodiment, while a black light source and photovoltaic device are used in a third embodiment. The energy harvesting wireless switch arrangement of the present invention can be combined, for example, with a vehicle side mirror switch, to reduce the complexity of the wire harness feeding the door. The wireless switch can be located without regard to accessability of a wiring harness or connector.

A biosensor provides for real time monitoring a selected aspect of an air conditioning or a refrigeration process and system. The biosensor includes a biocomponent element carrying a bioagent operative to detect one or more analytes indicative of the selected aspect of the climate control process to be monitored.

A hydrogen sensor ( ) protected from water vapor by a membrane ( ) indicates increases in hydrogen concentrations which are indicative of a leak in an absorption chiller ( ). A helium detector ( ), protected from water vapor and liquid water by a membrane ( ) and a vapor trap ( ), senses the presence of helium from a spray ( ) to locate the position of leaks. A hydrogen removing cell ( ) is tested by monitoring the variation with time of the hydrogen concentration before and after the cell is rendered inoperative.
