Anmbest 5PCS RED Microphone Sensor AVR PIC High Sensitivity Sound Detection Module LM393 Dual Differential Comparators Output for Arduino

• PRODUCT ADVANTAGES: The main chip is LM393. Signal is clean, waveform is good, driving ability is strong.
• ADJUSTABLE THRESHOLD: Build in potentiometer can be used to adjust the threshold level.
• EASY TO USE, INTUITIVE: When sound intensity exceed a certain threshold, produces low(Digital output 0) signal and light will be off, Otherwise output high(Digital output 1) signal and light will be bright.
• EASY TO INSTALL: There is a mounting screw hole, convenient fixed.
• WIDELY APPLICATIONS: a variety of platforms including Arduino / AVR / ARM/PIC.

<b> Technical Specifications:</b><br> Main chip:LM393, Electret condenser microphone<br> Operating voltage:3.3V - 5V<br> Output Form: Digital output(0 or 1) <br> PCB Size:32mm*17mm<br><br> <b> Output Pins:</b><br> VCC: connect 3.3V-5V voltage<br> GND:connect GND<br> OUT: signal output<br><br> <b> Instructions:</b><br> VCC is connected to 3.3V-5V voltage (can be directly connected to 5V MCU or 3.3V MCU), GND is connected to GND, and the power indicator will be on. Place the module in a quiet environment, adjust the blue potentiometer on the board until the switch indicator on the board is on, then trim back the potentiometer until the switch indicator is off, then generate a sound (such as a high-five) on the sensor accessory, The switch indicator light will be lit again.<br> When sound intensity exceed a certain threshold, produces low(Digital output 0) signal and light will be off, Otherwise output high(Digital output 1) signal and light will be bright. The module digital output OUT can be directly connected to the MCU, through the MCU. The high and low levels are detected, thereby detecting the sound of the environment, so that a voice switch can be formed.<br><br> <b>Package includes: </b><br> 5x Sound Detection Sensor Module
