XD-74 sound sensor module
- үнэ: 4,500 төг
This sensor can identify the presence or absence of sound (vibration according to the principle) does not recognize the size of the sound or the sound of a specific frequency.
Instructions:
1. the intensity of the sound module on the most sensitive to the ambient sound, is generally used to detect the intensity of the ambient sound.
2. modules at an ambient sound level of less than the set threshold, OUT output high when the ambient sound level exceeds the set threshold, the module OUT output low;
3. small plates OUT digital output can be directly connected to the microcontroller through the microcontroller to detect high and low, thereby detecting the sound environment;
Features:
1. Can detect the intensity of the ambient sound using
2. Adjustable sensitivity (shown in blue digital potentiometer adjustment)
3. Operating voltage 3.3V-5V
4. Digital outputs in the form of switch output (0 and 1 high and low)
5. With fixed bolt hole for easy installation
6. Small PCB board size: 3.2cm * 1.7cm
7. VCC external 3.3V-5V voltage (can be directly connected to 5v and 3.3v MCU )
8. GND external GND
9. OUT small plate switch output interfaces (0 and 1)
