Abstract
An alert system and method includes at least first and second detectors that each includes environmental condition detection circuitry, data processing circuitry, and wireless communication circuitry. The first and second detectors are respectively carried by first and second users. The first and second detectors detect environmental conditions in a vicinity of the respective detectors and communicate detection data to the respective data processing circuitry. In response to detection of a hazardous environmental condition by the first detector, the first detector provides an alert notification to the first user and communicates the alert to the second detector via wireless communication, and in response to receipt of an alert from the first detector, the second detector transmits the alert to another detector or device via wireless communication. A communicated or transmitted alert may include an incrementing indicator of a number of hops or levels of transmission of the alert.
