HC-SR501 Pyroelectric Infrared PIR Motion Sensor Detector detection Module

PIR sensor for Arduino,They are small, inexpensive, low-power, easy to use and don’t wear out. For that reason they are commonly found in appliances and gadgets used in homes or businesses. They are often referred to as PIR, “Passive Infrared”, “Pyroelectric”, or “IR motion” sensors.

Technical parameters:

Infrared sensor with control circuit board.

Features:   

PIR sensor for Arduino, They are small, inexpensive, low-power, easy to use and don’t wear out. For that reason they are commonly found in appliances and gadgets used in homes or businesses. They are often referred to as PIR, “Passive Infrared”, “Pyroelectric”, or “IR motion” sensors.

Technical parameters:

  • Color: White + Green
  • Weight: 7g (approx)
  • Dimension: 3.2cm x 2.4cm x 2.8cm (approx)
  • Working Voltage Range: DC 4.5V- 20V
  • Current drain:<60uA
  • The sensitivity and holding time can be adjusted
  • Voltage Output: High/Low level signal:3.3V TTL output
  • Detection distance: 3–7M(can be adjusted)
  • Detection angle: <140°
  • Delay time: 5-200S(can be adjusted, default 5s +-3%)
  • Trigger settings with jumper: Non-repeatable trigger  H: Repeat Trigger (default)
  • Work temperature:-20-+80°C
  • Trigger Method: L unrepeatable trigger / H repeatable trigger

Along with the pyroelectric sensor is a bunch of supporting circuitry, resistors, and capacitors. It seems that most small hobbyist sensors use the BISS0001 (“Micro Power PIR Motion Detector IC”), undoubtedly a very inexpensive chip. This chip takes the output of the sensor and does some minor processing on it to emit a digital output pulse from the analog sensor.
