PIR Motion Detection Sensor Module HCSR501

PIR Motion Detection Sensor Module HCSR501
PIR Motion Detection Sensor Module HCSR501

PIR Motion Detection Module HCSR501 for Electrical Switching Arduino Raspberry PI is a pyroelectric device that detects motion by measuring changes in the infrared (heat) levels emitted by surrounding objects. When motion is detected the PIR Sensor outputs a high signal on its output pin. This logic signal can be read by a microcontroller or used to drive an external load.


Detecting range : 360 degrees cone angle, 15-20 feet

Single bit output

Jumper selects single or continuous trigger output mode

3-pin SIP header

Small size makes it easy to conceal

Compatible with any microcontroller like Basic Stamp, Arduino, Atmega, PIC, 8051, propeller

Key Specifications:

Communication: Single bit high/low output

Operating temperature: 32 to 122 °F (0 to 50 °C)

Operating voltage:  DC 3.8V - 5V

Static power loss: ≤ 50 uA

Delay time: 30 Secs (0.5~900 Secs is optional)

Blockade time : 0.5s-50s (acquiescently 0 seconds)

Dimensions: 1.27 x 0.96 x 1.0 in (32.2 x 24.3 x 25.4 mm)

Key Differences:

Jumper setting controls triggering and not distance

Driving an external load requires a transistor or MOSFET

Detection range up to 20 ft away
