Description:

– 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 an 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 circuits.
• – Infrared technology (LHI778 probe design)
