What is the use of PIR Sensor?
PIR sensors are used in thermal sensing applications, such as security and motion detection. They are commonly used in security alarms, motion detection alarms, and automatic lighting applications.
How many types of PIR sensors are there?
Infrared sensors (IR Sensors) are the sensors that work on Infrared sensing technology to detect the motion of objects. There exist two types of sensors which detect motion with the help of Infrared, one is Active Infrared sensor (AIR sensor) and another one is Passive Infrared sensor (PIR sensor).
What are disadvantages of PIR Sensor?
Drawbacks or disadvantages of PIR sensor ➨They have lower sensitivity and less coverage compare to microwave sensors. ➨It does not operate greater than 35 degree C. ➨It works effectively in LOS (Line of Sight) and will have problems in the corner regions. ➨It is insensitive to very slow motion of the objects.
Does PIR Sensor work in sunlight?
These IR waves are also detected by the sensor aa it cannot distinguish based on the source of the IR waves. So, it will give wrong result . That’s why IR sensor doesn’t work accurately under sunlight.
What are the three types of motion detectors?
There are three types of motion sensors that are used frequently: Passive Infrared (PIR), Microwave, and Dual Tech/Hybrid.

How long does a PIR sensor last?
On average, a motion detector light will stay on for up to 20 minutes. That amount of time is extended each time a sensor detects fresh movement, so it is possible for a motion detector light to stay on for much longer than 20 minutes at a time.
