ABSTRACT:
Measuring the critical value of a parameter of a sensor in a security system (e.g., battery voltage) is performed at a time when the critical value is most likely to be reached, and the critical value information is sent from the sensor to a system controller at a time when the information is most likely to be successfully received.
