Abstract
A gas detector includes environmental condition detection circuitry that includes one or more sensors, data processing circuitry, and wireless communication circuitry. The gas detector is configured to be carried by a user. The environmental condition detection circuitry detects the presence or lack of presence of a particular gas in a vicinity of the gas detector and further detects a temperature in the vicinity of the gas detector and communicates detection data to the data processing circuitry. In response to detection of a hazardous temperature condition, the data processing circuitry of the gas detector provides an alert notification to the user carrying the gas detector. Also disclosed is an alert system including multiple gas detectors in which a first gas detector communicates an alert to a second gas detector via wireless communication, and in response, the second gas detector transmits the alert to another gas detector or device via wireless communication.
