An Early Warning Device for Detecting and Reporting Dangerous Conditions in a Community

摘要

An early warning device, system and method are disclosed. The early warning device includes a sensor which detects an environmental condition and a microprocessor which receives data from the sensor, analyses a change in the environmental condition over time and identifies a dangerous condition if the change in the environmental condition meets a threshold characteristic. A signal transceiver is connected to the microprocessor and sends an alarm signal to other early-warning devices in range if a dangerous condition is identified, and receives alarm signals from other early-warning devices in range. An alarm component connected to the microprocessor is activated by either the identification of a dangerous condition at the device or by receiving one or more alarm signals from other early warning devices in range, so that a plurality of early-warning devices are triggered in the event of a dangerous condition being identified at one or more of them.
