PIR Motion Sensor

The PIR Motion Sensor Module is a compact and efficient sensor designed to detect motion by measuring changes in infrared radiation (heat) emitted by objects—especially the human body. This passive infrared (PIR) sensor is widely used in motion-activated lighting, security systems, home automation, and IoT applications.

When motion is detected within its range, the sensor outputs a digital HIGH signal, making it ideal for microcontroller platforms like Arduino, ESP32, Raspberry Pi, and more. With adjustable sensitivity and delay time, the module offers flexibility in detecting movement over short or long distances.

This sensor is perfect for applications requiring energy-efficient motion detection, including automatic lights, security alarms, door entry systems, and presence-aware smart devices.

Key Features:

• ✅ Passive Infrared Technology
  Detects motion based on changes in heat (infrared radiation) in its environment.

• ✅ Digital Output
  Sends a HIGH signal when motion is detected—ideal for triggering alarms or devices.

• ✅ Adjustable Sensitivity & Delay Time
  Customize the detection range and output delay using onboard potentiometers.

• ✅ Wide Detection Range
  Typical detection range of 3–7 meters, with a 120° field of view.

• ✅ Low Power Consumption
  Ideal for battery-operated and energy-efficient smart home devices.

• ✅ Compact & Easy to Use
  3-pin connection (VCC, GND, OUT) allows for quick integration into electronics projects.

• ✅ Built-in Trigger Modes
  Supports both repeatable and non-repeatable trigger modes for flexibility in applications.
