YAHBOOM 3pin Voice Sound Detection Sensor Module intelligent Smart Vehicle Robot Helicopter Airplane Aeroplane Car for Arduino

Description
The sound sensor is suitable for use in all MCU development boards, development kits, and smart cars. Through the simple processing of the signal by the single-chip microcomputer, interesting experiments such as music fountain and voice control car can be realized. The sensor module only occupies one IO port, and the volume is judged by the signal length (vibration time). Only the vibration time can be measured, so the timbre and audio cannot be judged.
An detect the intensity of the sound environment, use note:the sound sensor can identify the presence of (according to the principle of vibration) or a particular frequency of sound does not recognize the volume of the sound
Sensitivity adjustable digital potentiometer to adjust (blue)
Working voltage 3.3 V-5 V
Output form digital switch output (1 s and 0 s + v)
Has a fixed bolt hole, convenient installation
Small board PCB size:3.2 cm * 1.7 cm
Module wiring instructions
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)
GND external GND
OUT of small plate switch output interface (0 and 1)
Feature
1. Sound module sound intensity is the most sensitive to the environment, commonly used to detect the intensity of the sound of the surroundings.
2. Module in the intensity of the sound environment than set threshold, the OUT output high level, when the intensity of the sound from the outside environment more than set threshold, the module OUT output low level;
3. Small digital output board OUT can be attached directly to the microcontroller, through single chip microcomputer to detect the high and low level, thus to detect sound environment;
Package included
1 x Voice Sound Detection Sensor Module
