Text and image detailsOutput model category: digital sensor1. It can detect the sound intensity of the surrounding environment. Note that this sensor can only recognize the presence or absence of sound (based on the principle of vibration) and cannot recognize the size or specific frequency of sound2 sensitivity adjustable (blue digital potentiometer adjustment in the figure)3. Operating voltage: 3.3V-5V5 output forms: digital switch output (0 and 1 high and low levels)6 with fixed bolt holes for easy installation7 small board PCB size: 3.2cm * 1.7cmTwo module wiring instructions1 VCC external 3.3V-5V voltage (can be directly connected to 5V and 3.3V microcontrollers)2 GND external GND3 OUT small board switch output interface (0 and 1)Three Instructions for UseThe sound module is most sensitive to environmental sound intensity and is generally used to detect the sound intensity of the surrounding environment.When the ambient sound intensity does not reach the set threshold, the OUT module outputs a high level. When the ambient sound intensity exceeds the set threshold, the OUT module outputs a low level;The digital output OUT of the 3 small boards can be directly connected to the microcontroller to detect high and low levels, thereby detecting environmental sounds;The digital output OUT of the 4 small boards can directly drive the relay module in our store, thus forming a voice controlled switch;Output model category: digital sensor1.
