Here's an overview of how it works and its typical applications:

Transmitter and Receiver: The system consists of two main components: an IR transmitter and an IR receiver. The transmitter emits a focused beam of infrared light, while the receiver is designed to receive the IR light.

Beam Interruption: The transmitter sends out a continuous or modulated IR beam toward the receiver. When no obstruction is present, the receiver continuously detects the emitted IR light.

Detection of Obstruction: If an object or person enters the path between the transmitter and receiver, it interrupts the IR beam. This interruption is immediately detected by the receiver.

Output Signal: The Single Beam Infrared Sensor provides an output signal to indicate whether the IR beam is continuously received or interrupted. When the beam is interrupted, the sensor typically sends a signal indicating an obstruction.

Usage Considerations:

Alignment: Proper alignment of the transmitter and receiver is crucial for accurate detection. They should be positioned to ensure a clear and unobstructed path for the IR beam.

Mounting Height and Angle: Consider the optimal mounting height and angle for the sensor to effectively detect approaching individuals or objects.

Range: Choose a sensor with an appropriate range to cover the desired detection area. Some models may offer adjustable sensitivity or range settings.

Power Supply: Ensure that the sensor receives the correct voltage (e.g., 12V) and power supply as specified in its documentation.

Weather Protection: If the sensor is installed outdoors, it may require weatherproofing to protect it from environmental conditions.

Testing and Calibration: After installation, it's important to test and calibrate the sensor to ensure it reliably detects obstructions or approaching individuals.
