What is A PIR motion sensor?

What are disadvantages of the PIR sensor?

A PIR motion sensor is a type of sensor that is used to detect movement. It is often used in security systems and can be used to detect the presence of people or animals. PIR sensors are not perfect, however, and there are some disadvantages to using them. One disadvantage is that they can be triggered by other things besides movement, such as changes in temperature. This can cause false alarms. PIR sensors can also be fooled by objects that are in motion, such as leaves blowing in the wind. Another disadvantage is that PIR sensors only work within a certain range, so they cannot be used to detect movement that is too far away. Overall, PIR sensors are a useful tool but they have some limitations.
