Abstract
Apparatus for monitoring an externally applied parameter to selected products. The invention involves a housing enclosing a sensor, and a monitoring and output network. The sensor has a characteristic that varies in some predetermined manner with variation in the monitored parameter. The monitoring and output network involves a sensor which produces a signal representative of the monitored characteristic. Values associated with the signal are stored in a memory device for subsequent, selected retrieval.
