The sound module is the most sensitive to the environment sound intensity, commonly used to detect the intensity of the sound of the surroundings. When module in the intensity of the sound environment can not reach a set threshold, the OUT will output a high level, when the intensity of the sound from the outside environment more than a set threshold, the module OUT output a low level; Small digital output board OUT can be direct to the microcontroller, through single-chip microcomputer to detect the high and low level, thus to detect sound environment;
- Can detect the intensity of the sound environment,
- working voltage 3.3-5V
- Output form: digital switch output (0 and 1)
- Has a fixed bolt hole,
- convenient installation
VCC voltage is 3.3 V to 5 V converter (which can be directly connected to 3.3 V or 5 V single-chip microcontroller)
GND external to GND
OUT of small plate switch output interface (0 and 1)
1 x Microphone Sound Sensor Module
digital output (0 and 1)
