  • Sound Detection Sensor Module - China

    price: contact company for price

    Feature: * The Sound sensor module is a simple microphone * Based on the power amplifier LM393 and the electret microphone * Any sound that beyond the threshold * The threshold can be adjusted by the on-board potentiometer
    * The product boast of output signal instruction.
    * Single-channel signal output.
    * Output valid signal is low and the light will be bright.
    * Can detect the ambient sound intensity, the use of Note: This sensor can only recognize the sound (according to the principle of vibration) can not identify the size of the sound or a specific frequency of sound
    * Adjustable sensitivity (figure blue digital potentiometer adjustment)
    * Output digital switch output (0 and 1 high and low level)
    * with fixing bolt holes for easy installation
    * Size: 3.1 x 1.6 x 0.8c
    * Working voltage: 3.3V-5V Wiring instructions:
    * VCC external 3.3V-5V voltage (which can be connected directly with the 5v microcontroller and 3.3v microcontroller)
    * GND External GND
    * OUT Small switch output interface (0 and 1) Instructions for use:
    * Sound module is the most sensitive to the ambient sound intensity and is generally used to detect the sound intensity of the surrounding environment.
    * When the ambient sound intensity is lower than the set threshold, the OUT output is high level. When the ambient sound intensity exceeds the set threshold, the module OUT outputs low level.
    * Small board digital output OUT can be connected directly with the microcontroller through the microcontroller to detect high and low levels, to detect the environment's sound;
    * Small board digital output OUT can directly drive the restaurant relay module, which can form a voice-activated switch;
