PIR Motion Sensor (Passive Infrared Sensor)

Description

HC-SR501 is based on infrared technology, automatic control module, using Germany imported LHI778 probe design, high sensitivity, high reliability, ultra-low-voltage operating mode, widely used in various auto-sensing electrical equipment, especially for battery-powered automatic controlled products.

Specification:

• Use BISS0001 signal processing IC, sanyo genius regulator

Application:

Automatically sensing light for Floor, bathroom, basement, porch, warehouse, Garage, etc, ventilator, alarm, etc.

Features:

• Automatic detecting: the output will be high when objects enter the sensing range, and automatically turn to low when object leave
• Photosensitive control (optional, not factory-set yet) can be set.
• Temperature compensation (optional, factory reset): In the summer when the ambient temperature rises to 30 C to 32 C, the detection distance is slightly shorter, temperature compensation can be used for performance compensation.
• Working mode (set by jumper)
  • Non-repeatable trigger/ delay mode (set to LOW): the sensor will turn to low TTL after the delay, even the sensing object is still in range.
  • Repeatable trigger (set to HIGH): the sensor will not turn to low if the object still staty in the sensing range in the delay time.
• Wide operating voltage range: default voltage DC4.5V-20V.
• Micro-amp power level consumption: static current <50 microamps, particularly suitable for battery-powered automatic control products.
• Output high signal: easy to achieve docking with the various types of circuit.
