HC-SR501 Infrared PIR Motion Sensor Module

HC-SR501 auto-senses light for various applications (in house, basement, outdoor, warehouse, garage, etc,) for ventilator control, alarm, etc.

Features

• Automatic infrared detection (LHI778 probe design)
  Output goes high when objects enter the sensing range, and automatically returns to low when object leaves
• Optional photosensitive control
• Optional temperature compensation
• Trigger mode jumper
• L: Non-repeatable / delay mode: sensor goes low after the delay, regardless of the presence of the object.
• H: Repeatable: sensor stays high as long as any object is detected during the delay time.
• Wide operating voltage range
• Micro-amp power
• Output high signal: easy to achieve docking with the various types of circuit.

• Infrared technology (LHI778 probe design)
• high sensitivity | high reliability
• widely used especially for battery-powered products.
