No, you probably haven’t seen this type of item used in an investigation before.
The idea is simple, if a smell you encounter is physical can we measure it and detect the makeup? What if an ”Entity” could produce something other than EMF? Anybody ever see a mist?
To bring the device together we built a small controller board with a microprocessor and a Bluetooth modem to capture the data remotely. Instead of relying on the LEDs to show the user what is going on the data stream sends out parts-per-million as a single line for all the sensors over the Bluetooth connection.
The case was 3D printed and the panels were all laser cut and engraved.
So how long did this take to build? Start to finish about 35 hours
The detector consists of eight sensors: Hydrogen, LPG, Methane Co2, Alcohol, Ozone, Coal Gas and Ammonia.
The sensor head features all eight sensors on the face
