Getting started with Arduino products
Atmel's ATMega328P 8-Bit Processor in 28 pin DIP package. It comes with 32K of program space. 23 I/O lines, 6 of which are channels for the 10-bit ADC. Runs up to 20MHz with external crystal. Package can be programmed in circuit. 1.8V to 5V operating voltage! The famous Arduino Deumilanove, and Arduino UNO is using this ATMega microcontroller. Anyhow, this microcontroller is fresh new without any bootloader.
This microcontroller is pre-loaded with Optiboot bootloader (Uno 16MHz). This means you can use Arduino code in your own project without using an actual Arduino Board. No programmer is needed anymore but you still need UC00A and basic circuit. Please select Arduino Uno Board in the Arduino IDE. We are using this microcontroller in our Breadboard Friendly Arduino (BBFuino). Therefore, you can refer to BBFuino's schematic and tutorial for more information.

Description:
PIR sensors, often referred to as, "Passive Infrared" or "IR motion" sensors, enable you to sense motion. Everything emits a small amount of infrared radiation (IR), and the hotter something is, the more radiation it emits. PIR sensors are able to detect a change in average IR levels of their detection zone (e.g. when a human enters a room, that room will increase in temperature slightly) and hence sense motion.
This one's great, as it can be powered via the Raspberry Pi's 5V output, and be read directly from the Raspberry Pi's GPIO input (as the sensor has a digital 3.3V output!)
This PIR includes an adjustable delay before firing (approx 0.5 - 200 seconds), has adjustable sensitivity and two M2 mounting holes! It runs on 4.5V-20V power (or 3V by bypassing the regulator with a bit of soldering) and has a digital signal output (3.3V) high, 0V low. Its sensing range is up to 7 meters in a 100 degree cone.

- Input Voltage: 4.5V - 20V
- Current Draw: <50µA
