What is pir sensor light

A PIR -based motion detector is used to sense movement of people, animals, or other objects. They are commonly used in burglar alarms and automatically- activated lighting systems. What are PIR or Infrared motion sensors , How they differ from other types of motion detectors and their usage in security flood lights and alarm systems.

Now when the PIR detects motion, the output pin will go high to 3. PIR sensors are more complicated than many of the other sensors explained in these tutorials (like photocells, FSRs and tilt switches) because there are multiple variables that affect the sensors input and output.

These motion detectors emit microwave signals and measure the time taken for the signal to be reflected back to the sensor, this is known as the echo time. The echo time is used to calculate the distances from all the stationary objects in the detection .
