HC-SR501 PIR Sensor

HC-SR501 PIR Sensor

Infrared for Arduino Raspberry Pi Micro: bit

Description

HC-SR501 PIR Sensor 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.

Specification:

• Product model: HW-SR501
• Working voltage: 3.7-20V
• Static power consumption: <50uA Level output: 3-0V (with induction 3V, no induction 0V)
• Delay time: 0-300S,
• potentiometer, adjustable.
• Induction distance: 1-10m,
• potentiometer, adjustable.
• Trigger mode: repeatable/non-repeatable, jumper, adjustable.
• Infrared lens: 8002-2B
• Sensing angle: 100

• Dimensions: 32 x 24 x 7mm +,
• OUT, – : Left and right input voltage,
• OUT signal output pin.
• RL: reserved interface for light control switch.
• The function is not working during the day and working at night, which is not added by default.
• RT: Thermistor reserved interface Distance: sensing distance (sensitivity) potentiometer, clockwise is large, counterclockwise is small Time:
• Delay time (high-level signal duration time)
• Potentiometer, clockwise is large, counterclockwise is small. H-L: H is the repeatable trigger mode, and L is the non-repeatable trigger mode.
• Note: The output level is not an absolute value, and changes in ambient temperature will affect it, and an error value of about 0.5V may appear. Package included: 1 x Infrared Sensor Detector Module
