1. Introduction
This evaluation kit provides a way to demonstrate the use of Cypress’s PSoC device to control a Pyroelectric
Infrared Sensor (PIR). The human body radiates a certain amount of infrared light, in the realm of about 10 µm
at normal body temperature. The concept behind PIR sensing is to capture this radiated light, filter the analog
signals, convert those signals to digital, and then use those signals to control hardware. In the case of this
evaluation kit, the conversion of these infrared rays to digital signals controls a relay and some LEDs. An
accompanying application note AN2105 titled, “Sensing - Pyroelectric Infrared Motion Detector, PSoC Style,”
which can be found on the documentation CD included with this kit, or on the Cypress website at
http://www.cypress.com/designresources, documents concepts of this design. This evaluation kit includes the
PIR Sensor evaluation board, a 12V power adapter, a PSoC Designer CD, and a documentation CD, which
includes design files, a firmware example project to demonstrate the operation of the PIR Sensor, and the
aforementioned application note and this user guide in .pdf format.
