When an object comes within the sensor's range, the amount of reflected light changes, causing the sensor’s output to switch state. Arduino Processing: The Arduino reads the output from the IR sensor.

Functionality: IR Sensor Detection: The IR sensor is connected to digital pin 7 and is used to detect the presence or absence of an object (e.g., the door). LED Indicator: An LED connected to digital ...

With strong reflectance, the output voltage tends towards GND; with weak reflectance, it tends towards Vcc. The resistor wired in series with the infrared LED sets the operating current to a safe ...

VCC - Provides power for the module, Connect to the 5V pin of the Arduino. GND - Ground Connected to Ground pin of the Arduino. SCL – Module output (HIGH (3.3 V) motion detected/LOW (0 V) idle). CDS – ...

The sensor operates at 5V for Arduino and 3.3V for Raspberry Pi, ensuring seamless integration with these popular microcontroller and microcomputer platforms.
