What is a PIR Motion Sensor: PIR IC Working, Features and ...

A PIR or a Passive Infrared Sensor can be used to detect presence of human beings in its proximity. The output can be used to control the motion of door. Basically motion detection use light sensors to detect either the presence of infrared light emitted from a warm object or absence of infrared light when a object interrupts a beam emitted by another part of the device.

Passive Infrared Sensors /PIR Sensors Applications

Introducing a PIR sensor in a system that uses a stepper motor will automate the system so that the motor movement will only occur when the sensor detects nearby movement. All these may seem complicated, but several hospitals, kitchen, and bathrooms work by this principle. Some of the applications include automatic toothpaste dispensers, hands-free liquid soap dispensers, no-contact …

Passive Infrared Sensors /PIR Sensors Applications

Passive Infrared sensors or PIR sensor is an electronic device that detects infrared light radiating from an object. This object could be human or animal. It does not emit waves like an active sensor since it is a passive sensor. Instead, it measures any significant increase in the energy level within its field of view.
