HCSR501 PIR Motion Sensor (Passive Infrared Sensor)
HCSR501 PIR Motion Sensor
The PIR Motion Sensor Detector Module HC-SR501 allows you to sense motion. It is almost always used to detect the motion of a human body within the sensor’s range. It is often referred to used “PIR”, “Pyroelectric”, “Passive Infrared” and “IR Motion” sensor.
The module has an onboard pyroelectric sensor, conditioning circuitry, and a dome-shaped Fresnel lens. It has a delay time adjustment Potentiometer and sensitivity adjustment Potentiometer. Repeat Trigger Selection Jumper is also available. Compatible with arduino,Rasberry Pi,AVR, PIC, 8051, etc.

Can a PIR sensor detect fire?
Whenever there is an activity within the viewing range of the PIR sensor system, the sensor signal is analyzed in the wavelet domain and the wavelet signals are fed to a set of HMMs.
