LOW POWER MOVEMENT SENSOR

摘要

A detection system for monitoring and recording distance to at least one target. The detection system may comprise at least one module comprising: a power source; a trigger unit configured to detect the presence of the target; an enablement mechanism in communication with the trigger unit and operable to generate an enablement signal upon detection of the target; a data gathering unit comprising at least one measurement sensor operable to obtain at least one measured parameter and to record the at least one measured parameter in a memory; and a retrieval mechanism for providing access to records stored in the memory.

1. A detection system for monitoring and recording distance to at least one target, said detection system comprising at least one module comprising:
a power source; a trigger unit configured to detect the presence of said target and operable to generate an enablement signal upon detection of said target; a data gathering unit comprising at least one measurement sensor operable to obtain at least one measured parameter and to record said at least one measured parameter in a memory; and a retrieval mechanism for providing access to records stored in said memory; wherein said trigger unit comprises a passive detector and said measurement sensor is operable to draw power from said power source only when the enablement signal is received from said trigger unit.
