Jopto 5PCS KY-037 High Sensitivity Microphone Sound Voice Detection Sensor Module Compatible with Arduino Raspberry Pi AVR PIC

• High Sensitivity Sound Microphone Sensor Detection Module, used for sound detection.
• Working Voltage: 5V; Use 5v DC power supply.
• The module has two outputs: AO, analog output, real-time output voltage signal of the microphone.
• DO, when the sound intensity reaches a certain threshold, the output high and low signal.
• There is a power indicator light, and the comparator output has an indicator light.

Feature: 1. There is a 3mm mounting screw hole. 2. Use 5v DC power supply. 3. With analog output. 4. With Threshold flip level output. 5. High sensitive microphone. 6. There is a power indicator. 7. The output of the comparator has an indicator light. The module has 2 outputs: 1. AO, analog output, real-time output of microphone voltage signal. 2. DO, when the sound intensity reaches a certain threshold, output high and low level signals. (Threshold sensitivity can be adjusted by potentiometer. ) Size: 43 × 15 × 13 mm Weight: 3.6 g Package Content: 5 x Sound Microphone Sensor Detection Module
