High-sensitivity microphone sensor module KY-037 sound module sound detection

Purpose: Sound detection.

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]

Module features:

2. There is a 3mm mounting screw hole

3. Use 5v DC power supply

4. There is an analog output

5. Threshold flip level output

6. High-sensitivity microphone with high sensitivity.

7. There is a power indicator

8. The output of the comparator has an indicator light
