Package Included

- 1 × Sound Detection Module

Description:

- Can detect the intensity of the sound environment
- Sensitivity adjustable digital potentiometer to adjust (blue)
- 3-5 V working voltage 3.3 V
- Output form digital switch output (1s and 0s + v)
- Small board PCB size: 3.2 cm * 1.7 cm
- VCC voltage is 3.3 V to 5 V converter (which can be directly connected to 5 V single-chip microcontroller and 3.3 V)
- OUT of small plate switch output interface (0 and 1)
- Sound module sound intensity is the most sensitive to the environment, commonly used to detect the intensity of the sound of the surroundings.
- Small digital output board OUT can be attached directly to the microcontroller, through a single-chip microcomputer to detect the high and low level, thus to detect sound environment;
