SS-101A PIR sensor

SKU: 3204585. Category: . Tags: , , .

Product 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
  • Voltage: 5V – 20V
  • Power Consumption: 65mA
  • TTL output: 3.3V, 0V
  • Delay time: adjustable (0.3 sec – 10 minutes)
  • Lock time: 0.2 sec
  • Trigger methods: L – disable repeat trigger, H enable repeat trigger
  • Sensing range: less than 120 degree, within 7 meters
  • Temperature: – 15 ~ +70
  • Dimension: 32*24 mm, distance between screw 28mm, M2, Lens dimension in diameter: 23mm

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.

Adjustment:

  • Adjust the distance: turn the potentiometer clockwise rotation, increased sensing distance (about 7 meters), on the contrary, the sensing distance decreases (about 3 meters).
  • Adjust the delay: turn the potentiometer clockwise rotation sensor the delay lengthened (600S, 10 minutes ), on the contrary, shorten the induction delay (0.3 second).

    (verified owner):

    I have purchased and used many of these. I usually combine them with relays to make motion-sensing room light switches. They have been robust, reliable, and sensitive. I recommend them highly.
