The sensor detects infrared radiation (IR) emitted by humans and animals. When a moving object with heat (like a person) passes within its detection range, the sensor triggers a signal, making it ideal for motion detection.
The sensor has a digital output, which is either HIGH (when motion is detected) or LOW (when no motion is detected). It can be connected to microcontrollers like Arduino to trigger actions like alarms or lights.
Yes, the delay time (the amount of time the output remains HIGH after motion is detected) can be adjusted from 5 seconds to 5 minutes using a potentiometer on the module.
Connect VCC to the 5V pin, GND to ground, and OUT to a digital input pin on the microcontroller. When motion is detected, the output pin will go HIGH, signaling movement.
The sensor is typically used indoors, but with proper housing or protection from weather, it can be used outdoors in security systems, provided it's shielded from direct exposure to moisture.
