ABOUT ARDUINO UNO

Each Arduino board has its own microcontroller (ATmega328). You can accept it as the cerebrum of your board. The principle IC on the Arduino is somewhat not quite the same as board to board. The microcontrollers are more often than not of the ATMEL Company. You should comprehend what IC your block has before stacking another program from the Arduino IDE. This data is accessible on the highest point of the IC. Link



ABOUT PIR MOTION SENSOR

Description:-

The Passive Infrared device (PIR) device module is employed for motion detection. It's typically mentioned used "PIR", "Pyroelectric", "Passive Infrared" and "IR Motion" device. The module has associate degree on-board electrical phenomenon device, acquisition electronic equipment and a dome formed lens, it's accustomed sense movement of individuals, animals, or alternative objects. they're normally employed in stealer alarms and automatically-activated lighting systems.Link
