This 5V HC-SR501 PIR motion sensor is a passive infrared (PIR) sensor that detects the movement of humans or animals. PIR motion sensor is based on infrared technology, which means that it can detect the heat signature of a moving object. The HC-SR501 is a very sensitive sensor, and it can use in a variety of applications

This PIR motion sensor HC-SR501is a great way to add motion detection to your Arduino projects. HC-SR501 is a passive infrared sensor that detects changes in infrared light. This means that it can detect motion from humans and animals, but it will not be affected by light or other sources of infrared radiation.

The PIR Motion Detector Sensor Module HC-SR501  also has two potentiometers on the back of the module. These potentiometers are use to adjust the sensitivity and the delay time of the sensor.

The PIR motion sensor HC-SR501 is a passive infrared (PIR) sensor. HC-SR501 Infrared Pir Motion Sensor works by detecting changes in the infrared radiation levels emitted by surrounding objects. When a warm object, such as a human or an animal, enters the sensor’s field of view, it will emit more infrared radiation. This change in radiation levels is detected by the sensor, and it outputs a high signal on its output pin.

The HC-SR501 PIR Motion Sensor Module is a very sensitive sensor, and it can detect motion from a distance of up to 7 meters. SR501 PIR Sensor also has a built-in delay timer, which prevents it from being triggered repeatedly by the same movement.

The sensing range of the HC-SR501 motion sensor is about 7 meters. This range can adjust by turning the sensitivity potentiometer. Turning the potentiometer clockwise will increase the sensing range, while turning it counterclockwise will decrease the sensing range.

The HC-SR501 also has a built-in delay timer that prevents it from being triggered repeatedly by the same movement. This is useful to prevent the sensor from being triggered by things like wind or shadows.

The Pyroelectric Motion Sensor (HC-SR501) can power by a voltage source of 4.5 to 12 volts. The recommended voltage is 5 volts.

Features : –

The PIR motion sensor HC-SR501 can use as a standalone unit, or it can connect to a microcontroller such as the Arduino. When connected to a microcontroller, the HC-SR501 can use to control a variety of devices, such as lights, alarms, and motors.

The PIR motion sensor HC-SR501 is a very versatile sensor. SR501 PIR Motion Sensor has a number of features that can be customized to meet the specific needs of the application. The PIR Motion Sensor HC SR501 has a number of benefits, including:

5V HC-SR501 PIR Motion Sensor Specifications : –

The Pyroelectric Motion Sensor (HC-SR501) has an onboard pyroelectric sensor, conditioning circuitry, and a dome-shaped Fresnel lens. The pyroelectric Motion sensor is the heart of the sensor.

HC SR501 Motion Sensor detects changes in infrared radiation levels. The conditioning circuitry amplifies the signal from the pyroelectric sensor and converts it into a digital signal. The Fresnel lens focuses the infrared radiation onto the pyroelectric sensor. Here are the specifications of the PIR Motion Sensor HC SR501:

  • Operating voltage: 4.5 to 12 volts
  • Current consumption: 12 mA
  • Sensitivity: Adjustable from 3 to 7 meters
  • Delay time: Adjustable from 3 seconds to 5 minutes
  • Output: Digital output, 3.3V when motion is detected, 0V when no motion is detected
  • Dimensions: 32 x 24 x 25 mm
  • Weight: 20 grams

5V HC-SR501 PIR Motion Sensor Pin Descriptions : –

One of the most customizable features of the HC-SR501 is the delay time. The delay time is the amount of time that the sensor will wait after it detects motion before it can be triggered again. The delay time can adjust from 3 seconds to 5 minutes. This feature is useful for preventing the sensor from being triggered repeatedly by the same movement.

Another customizable feature of the HC-SR501 is the sensitivity. The sensitivity is how easily the sensor is triggered by motion. The sensitivity can adjust from low to high. A higher sensitivity setting will cause the sensor to be triggered by more subtle movements, while a lower sensitivity setting will cause the sensor to be triggered by only larger movements. The HC-SR501 PIR motion sensor has three pins:

  • VCC: This is the power input pin for the sensor. It can connect to a voltage source of 4.5 to 12 volts.
  • OUT: This is the output pin for the sensor. It goes high when motion detected and low when no motion detected.
  • GND: This is the ground pin for the sensor. It should connect to the ground of the power supply.
