Introduction
This wavelength kit demonstrates the use of Cypress’s PSoC
®
device to control a pyroelectric Infra-
red (PIR) sensor. The human body radiates a certain wavelength of infrared light – 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 digital signals to control hard-
ware. In the PIR Motion Sensor Evaluation kit, the conversion of these infrared rays to digital signals
controls a relay and some LEDs.
The CY3236A-PIRMOTION EVK includes all of the software, hardware, code examples, and docu-
mentation you need to implement all of these PIR sensing control functions in one flexible and pow-
erful PSoC device, the CY8C27443. An application note, AN2414, “
Proximity Sensing Using PIR
” is
available on the Cypress website at
http://www.cypress.com/?rID=2794
.
Chapter 2 of this document describes the installation and configuration of the kit software. Chapter 3
explains the programming of a PSoC 1 device with PSoC Programmer. Chapter 4 describes the
hardware operation. Chapter 5 provides instructions on how to use the kit with the help of a code
example. The Appendix provides the schematics, layout, and bill of materials (BOM) for the kit.
