1. What it is

The Atmel SAM4S-WPIR-RD is a complete reference-design kit that demonstrates

a

low-cost, battery-powered "smart" motion-detector camera, the kind used in

home/building alarm and monitoring systems. When the on-board passive

infrared (PIR) sensor detects motion it wakes up, snaps an image with the on-

board CMOS camera, shows it on the small color TFT screen, and can transmit

over an optional ZigBee wireless module. It is built around Atmel's (now

Microchip) SAM4S 32-bit ARM Cortex-M4 microcontroller and is meant for

engineers evaluating/prototyping this class of product, not as a consumer

device.
