Abstract

A system includes a plurality of sensors and a monitoring system that are capable of wireless communication. A first of the sensors senses information relating to a specified condition and sends a wireless message with information relating to the specified condition to a second of the sensors. The first sensor also sends another wireless message relating to the specified condition to the monitoring system. The second sensor may also sense information relating to the specified condition, and the message sent to the monitoring system may include information derived from the information sensed by both the sensors. The second sensor may modify its functionality in response to the wireless message sent by the first sensor.
