Pyro

In this search i introduce pyro. This is a technique by using Infrared signal radiated from the fingers. Pyro uses passive infrared sensors raffers to APIR made with pyro electric material. Which is used to detect human motion in order to sensor's range. A digital hive is generated when human notion is detected.
The PIR sensor consists of two pyro electric elements which are sensitive to infrared signals made it from human body.
When the sensor is idle, both elements detect the same amount from the envoirnment. When a warm body passes through 1st signal it show possitive differential change.

To demonstrate the feasibility of Pyro, we developed a self-contained prototype consisting of the infrared pyroelectric sensor, a custom sensing circuit, and software for signal processing and machine learning.
