These devices will detect your pot smoke without you ever even knowing they were there. Hotel rooms, college dorms, bars, apartment complexes, and any other room, public or private, may soon be armed with a silent watchdog that will know if you light up. A five person startup out of Lebanon, New Hampshire called FreshAir Sensor is responsible for these hall monitoring devices that are sensitive enough to detect even secondhand smoke of both the marijuana and cigarette varieties. These detectors are ultra sensitive to smoke, and you cannot bribe them to keep quiet.

This spy tool comes in two different models. One model plugs into a wall outlet, and the other is designed to be worn on clothing. Both models will continuously check the surrounding air for marijuana and nicotine particles. Each device reports the collected data a little differently, and the differences are explained below.

The first model plugs into any standard wall power outlet, and conveniently provides pass through access so it will not obstruct your power needs. It is shaped similarly to a plug-in carbon monoxide monitor. In this model, an on-board memory system records smoke violations and reports them to a central monitoring system using a Wi-Fi connection. It can be programmed to immediately notify a chosen someone of the detected smoke particles by email.

Even more invasive, the wearable, battery-powered version of the doobie-detector is small enough to fit in the palm of your hand, and is scheduled to be on the market by next spring. This model can be programmed to detect either marijuana or cigarette smoke, or both. The time that the smoke is detected is permanently recorded to an internal memory. This model uses Bluetooth communication, and the owner may use the system’s Android app to retrieve information in real time.

Either one of these models could easily be used by a parent to secretly spy on their teen’s smoking habits. Because of these, college dorms may never be as free again, and some renters may have to forfeit the security deposit. Think twice next time you consider lighting up in your hotel room, or at least scour for these tiny tattlers first.
