WHAT IS A SENSOR
A sensor is a type of device that has been programmed to measure or detect a physical property and then carry out a task by responding to it.
WHAT IS A PIR MOTION SENSOR
A PIR motion sensor is a passive infrared sensor
A PIR motion sensor has a specific field of view in which it detects motion to carry out a task
WHAT A PIR MOTION SENSOR IS USED FOR
PIR motion sensors use infrared sensors to detect motion to check if a signal should be sent to carry out the next task
For a PIR motion sensor the next task would be to sound an alarm because these sensors are most commonly used for burglar alarms.
HOW IT IS USED IN EVERYDAY LIFE
PIR motion sensors are used for security purposes in everyday life for example a burglar alarm
HOW ITS USED IN MY WORK
I done a project where I used a bread board to connect the PIR motion sensor with a speaker to create a burglar alarm
When the motion sensor picked up any movement it would send a signal to the speaker which will make it project a noise
