US 11,232,704 B1 · Smoking detection device with tamper countermeasures

Abstract

A smoking detection device with tamper countermeasures is disclosed. A smoking detection circuit includes a smoke and gas sensor is configured to detect a smoking event within an enclosed space of a property, such as a vehicle or a hotel room. Tamper countermeasures prevent a renter from interfering with the detection function of the smoking detection device. The device also includes an event recording element that provides an evidentiary backup in the event of a power failure of the smoking detection device. The event recording element includes a light emitter that is triggered by one or more of smoking detection event and a tamper event. The light emitter exposes a patch of photo sensitive material, that once exposed provides for a visual means of identifying a smoking event or a tamper event during a rental period.

A smoking detection device, comprising:

a housing;
a smoking event detection circuit contained within the housing, the smoking event detection circuit including a smoke and a gas sensor configured to activate on a detection of a smoking event;
a tamper detection circuit contained with the housing, the tamper detection circuit configured to detect a presence of a proximity tampering event by a covering object placed in a close proximity to the smoke detection device;
and
an event recorder element comprising a patch of a photosensitive material that is configured to be exposed responsive to an activation of the smoking event detection circuit or the tamper detection circuit to provide a tangible record of one or more of the smoking event and a proximity tamper event detected by the smoking event detection circuit and the tamper detection circuit.
