    Description

    The LM393 Sound Detection Sensor Module KY-038 is High Sensitivity Microphone Sensor which is a small, easy-to-use and can use to detect sound levels. HW-484 Sound Detection Sensor Module has four pins: VCC, GND, OUT, and AO. The VCC and GND pins are used to supply power to the module, the OUT pin is the digital output pin, and the AO pin is the analog output pin.

    The output of this module is both analog and digital. The digital output acts as a key, and it activates when sound intensity has reached a certain threshold. The analog output voltage changes with the intensity of sound received by the microphone. You can connect this output to Arduino analog pins and process the output voltage.

    KY038 Sound Detection Sensor Module is Arduino compatible and based on LM393 OP-AMP which detects whether the sound has exceeded a threshold value. In the LM393 Sound Detection Sensor Module, the op-amp is used to amplify the signal from the microphone and compare it to a reference voltage. The reference voltage is set by the potentiometer on the sensor.

    The LM393 Sound Detection Sensor Module can power by a voltage between 3V and 5V. The input voltage is supplied to the VCC and GND pins on the module. The operating voltage of the module is determined by the voltage that is supplied to the VCC pin.

    This Digital Sound Detection Sensor Module KY-038 also has two LEDs: a power LED and a signal LED. The power LED turns on when the module is powered on, and the signal LED turns on when the sound level exceeds a certain threshold.

    Overall, the HW-484 Digital sound detection sensor module is a versatile and a good choice for projects that require a small, lightweight, and reliable sound detection module.

    Features : –

It comprises an on board potentiometer to adjust the set point for sound level. This module can use for security, switch, and monitoring applications. Its accuracy can easily adjust for the convenience of usage.

    It can use to detect sound levels, control devices based on sound levels, or collect data on sound levels. The LM393 Sound Detection Sensor Module can use in a variety of applications, such as:

    Security systems: The LM393 Sound Sensor Module can use to detect noise levels and trigger an alarm if the noise level exceeds a certain threshold.
    Home automation: The LM393 Sound Sensor Module can use to control lights or other appliances based on the sound level.
    IoT devices: The LM393 Sound Sensor Module can use to collect data on sound levels and send it to a cloud server.
    LM393 Sound Detection Sensor Pin Description : –
    LM393 Sound Sensor Module is a reliable module that is known for its stable performance. It has a signal-to-noise ratio of >50dB, which means that it can accurately detect sound levels even in noisy environments. This Digital microphone Sensor Module is easy to use and can interface with a variety of microcontrollers. It comes with a potentiometer that can use to adjust the sensitivity of the sensor.

    The Digital Sound Sensor Module has four pins:

    VCC: The VCC pin is the power supply pin. It should connect to a voltage between 3V and 5V.
    GND: The GND pin is the ground pin. It should connect to a common ground.
    OUT: The OUT pin is the digital output pin. It will output a high voltage when the sound level is above a certain threshold.
    AO: The AO pin is the analog output pin. It will output an analog voltage that is proportional to the sound level.
    Package : –
    1 x LM393 Sound Detection Sensor
