SS-101A PIR sensor

SKU: SMO1060 Category: Tags: , ,

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:

Voltage 4.8V – 20V
static current <50 uA
TTL output 3.3V / 0V
Delay time 0.3S – 200S, custom up to 10M
Lock time 2.5S Default
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

screw-screw 28mm, M2

Lens diameter: 23mm

  • 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.

  1. remymorra (verified owner)

    Very useful product, easy to use, does not require any special capability, very good mark 😀

  2. schnetzi (verified owner)

    First, I had some troubles reading the right values. But after adjusting the photosensitive and temperature compensation controls it worked perfectly 🙂

  3. balaji (verified owner)

    Seems perfect. Just use any arduino available sketch for this PIR. Works very well.

  4. yfands (verified owner)

    The description says it all, very good product and affordable.
    If you want a good and reliable proximity sensor, buy this.

  5. Elad (verified owner)

    Good build quality and nice design!

  6. zemlin (verified owner)

    As everybody says this is a great Device. I’m using it for building my DIY alarm system and plan on using for Home Automation

    how to drive relay from hcSr501

  8. reedv (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.

  9. Joe (verified owner)

    Works far better than i thought possible. Flawless.

  10. cbbxl (verified owner)

    They work great. I’m using 16 of them, directly on 12V to trigger logic MOSFETs, on autonomous installations (without Arduino or board)
    Con: TTL output do not drive enough current to directly trigger some 12V relays, that’s why I’m using logic level MOSFET transistors (ex: MTP3055VL), which are finally more elegant than relays for DC current.

  11. cromdeveloper (verified owner)

    Very good product!!

  12. geraldhasmail (verified owner)

    I’m using these with Arduinos for security devices, and they have all worked quite well.

  13. diazfjg (verified owner)

    Easy to use and good quality.
