The HC-SR501 PIR Sensor (Motion Sensor)

is a versatile module that can be used in various applications. It is a motion detection module that is perfect for your DIY projects. The module is easy to use and can detect motion up to 7 meters away. It is ideal for security systems, automatic lighting systems, and other applications that require motion detection.

The HC-SR501 PIR Sensor (Motion Sensor) is a passive infrared sensor that detects changes in infrared radiation. It has a built-in amplifier that amplifies the signal and sends it to the output pin. The module has two potentiometers that allow you to adjust the sensitivity and the delay time. The sensitivity potentiometer adjusts the range of the sensor, while the delay time potentiometer adjusts the time the output stays high after detecting motion.

The HC-SR501 PIR Sensor (Motion Sensor) is easy to use. It has three pins: VCC, GND, and OUT. Connect VCC to 5V, GND to ground, and OUT to a digital pin on your microcontroller. When motion is detected, the output pin goes high. The module is compatible with Arduino, Raspberry Pi, and other microcontrollers.

Product Specification:

• Operating Voltage: DC 4.5V – 20V
• Static Current: <50uA
• Output Signal: 0,3V (Output Low), 3V (Output High)
• Sensing Angle: <100 degrees cone angle
• Sensing Distance: 3-7 meters
• Delay Time: 5-200 seconds (adjustable)
• Trigger Mode: L: Non-repeatable trigger H: Repeatable trigger (default)
• PCB Dimensions: 32mm x 24mm x 25mm

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.
