ABSTRACT:
An alerting apparatus for alerting residents to hazardous gas concentrations, comprising an alarm clock, a gas sensor, a microcontroller, and visual display and auditory speech warning means for producing a wake-up alarm and a hazardous gas warning. When the alerting apparatus detects a dangerous level of carbon monoxide, initial visual display and auditory speech warnings are provided to the user using a digital display and a voice synthesizer. The visual and speech warning messages provide the user with warnings and instructions appropriate to the concentration of gas detected and time of exposure. The user may then retrieve further visual and auditory messages which provide a detailed gas detection event history.
