IR Sensor Module

IR Sensor Module 

Components:

1. IR Emitter (Transmitter): Usually an IR LED that emits infrared light.
2. IR Receiver: Typically a photodiode or phototransistor that detects the reflected IR light.
3. Comparator Circuit: Compares the received signal to a reference value to produce a digital output.
4. Potentiometer: Allows adjustment of the sensitivity or range of the sensor.
5. Indicator LED: Often included to indicate when an object is detected.
6. Output Pin: Provides a digital or analog signal based on the detected infrared light.
