Sound Blue：
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)
3-5 V working voltage 3.3 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)
Three instructions
Sound module sound intensity is the most sensitive to the environment, commonly used to detect the intensity of the sound of the surroundings.
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;
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;
Small digital output board OUT this shop can be directly driven relay module, which can form a voice-activated switch;
Sound Black：
Features
1. Dimensions: Length 32mm X Width 17mm X Height 15mm
2. Main chip: LM393, electret microphone
3. Working voltage: DC 4~6V
4. Features:
1. With signal output indication.
2. Single signal output.
3. The output valid signal is low level.
4. When there is a sound, it outputs low level and the signal light is on.
5. It can be used for sound-controlled lights, with photosensitive sensors for sound and light alarms, sound control, and sound detection.
6. Circuit board output switch value!
