HC-SR501 PIR Sensor

The HC-SR501 PIR (Passive Infrared) sensor is a motion detector that uses infrared technology to detect the movement of people, animals, or other objects. It is commonly used in security systems, automatic lighting control systems, and other applications where motion detection is needed.

The sensor has a sensing range of up to 7 meters and an adjustable delay time of up to 60 seconds. It also has a built-in infrared sensor and a signal output indicator LED. The sensor output is a digital signal which can be easily read by a microcontroller or other electronic devices.

It can be powered by a voltage range from 4.5V to 20V and its low power consumption, small size, and easy to use makes it a popular choice for many DIY projects and commercial applications, such as automatic lighting, security systems, and motion-activated devices.

The HC-SR501 PIR sensor is a low-cost and easy-to-use motion sensor that is well-suited for a wide range of applications.

Features:

  • Automatic Induction: to enter the sensing range of the output is high, the person leaves the sensing range of the automatic delay off high, output low.
  • Photosensitive Control (optional, not factory-set) can be set photosensitive control, day or light intensity without induction.
  • 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.
  • Triggered in two ways: (jumper selectable)
  • Non-repeatable trigger: the sensor output high, the delay time is over, the output is automatically changed from high level to low level;
    repeatable trigger: the sensor output high, the delay period, if there is human activity in its sensing range, the output will always remain high until the people left after the delay will be high level goes low (sensor module detects a time delay period will be automatically extended every human activity, and the starting point for the delay time to the last event of the time).
  • With induction blocking time (the default setting: 2.5s blocked time): sensor module after each sensor output (high into low), followed by a blockade set period of time, during this time period sensor does not accept any sensor signal. This feature can be achieved sensor output time “and” blocking time “interval between the work can be applied to interval detection products; This function can inhibit a variety of interference in the process of load switching. (This time can be set at zero seconds – a few tens of seconds).
  • Wide operating voltage range: default voltage DC4.5V-20V.
  • Micropower 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.

What does PIR stand for?

PIR means “Passive Infrared”

Where are PIR sensors used?

PIR sensors are used in thermal sensing applications, such as security and motion detection. They are commonly used in security alarms, motion detection alarms, and automatic lighting applications.

Their main difference is that IR sensors detect whether the light from the transmitter is emitted by an object or a person. Whereas, PIR sensors detect changes in the levels of energy around the area.
The best placement for a motion sensor is in a corner of the room that has a good viewpoint of your entryways and easily detect any changes in the room.
