PIR Motion Detection Sensor HC-SR501 for Arduino/Raspberry-Pi/Robotics
This is a Pyrolectric sensor(PIR) module which developed for human body detection.Its is also called Motion Sensor.A PIR detector combined with a Fresnel lens are mounted on a compact size PCB together with an analog IC , and limited components to form the module. It detect the motion by detecting the changes in the IR levels emitted from the object.It can be used as motion detector for security systems or robotics. It works from 3.3 V to 5 V DC and gives TTL output which can be directly given to microcontroller or to relay through a transistor.
Applications of PIR Motion Detection Sensor HC-SR501:
- Range Finder.
- Distance Sensor.
- DIY projects for various Robot designs.
