    LM393 IR PROXIMITY SENSOR

    LM393 IR PROXIMITY SENSOR thumbnail
    A general infrared proximity sensor circuit that can be interfaced with any microcontroller (e.g., Arduino, ESP, etc.). It uses a transmitter (IR LED) and a receiver (photodiode) along with a comparator circuit (LM393N/NOPB) to sense objects. The circuit outputs a digital signal (high/low) based on the sensor's response.
