Sound Amplifier Module High Sensitivity Microphone Analog High Low Level Output Voice Sound Detection Sensor Module
Product Description
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]
Title goes here.
1. There is a 3mm mounting screw hole
2. Use 5v DC power supply
3. There is an analog output
4. Threshold flip level output
5. High sensitivity microphone with high sensitivity.
6. There is a power indicator
7. The output of the comparator has an indicator light
This module uses professional microphone amplifier IC, with low output noise, small size, high sensitivity, fixed gain at 20dB, and can support both 3.3v and 5v power supply modes.
