Microphone Sensor High Sensitivity Sound Detect Voice switch Module For Arduino

Description: Descriptions: Product Features:The sound module is the most sensitive to the ambient sound intensity and is generally used to detect the sound intensity of the surrounding environment.The sound module is most sensitive to the sound intensity of the environment, and is generally used to detect the sound intensity of the surrounding environment. Adopts LM393 comparator output, clean signal, good waveform, strong driving ability, more than 15mA, with fixed bolt holes, easy to install and fix. Blue digital potentiometer can adjust the sensitivity. Product Parameters:Working voltage:3.3V-5VOutput form: digital switching output (0 and 1 high and low level)PCB size:3.2cm * 1.7cm Instructions for use of the product VCC external 3.3V-5V voltage (can be directly connected with 5v microcontroller and 3.3v microcontrollerconnected), GND external GND, the power indicator will light. Place the module in a quietenvironment, adjust the blue potentiometer on the board until the switch indicator on the board is on, thenfine-tune back and forth until the switch indicator is off, and then generate a sound near the sensor (e.g., high-five).sound (e.g. high-five) near the sensor, the switch indicator will go to the lit state again, indicating that the sound can come out of theThe module will be able to produce sound when the ambient sound intensity does not reach the set level. Module in the ambient sound intensity does not reach the set threshold, OUT output high level, when theExternal environmental sound intensity exceeds the set threshold, the module OUT output low level; smallboard digital output OUT can be directly connected with the microcontroller, through the microcontroller to detect theHigh and low level, thus to detect the environmental sound; small board digital output OUT can beThe digital output OUT of the board can directly drive our relay module, which can form a sound-controlled switch. Note:Pro please refer to our foot order in detail, at the same time against your host foot order, seewhether it is the same. If the distance requirement is farther, you can connect the antenna of 1/4 wavelength, generally using 50 ohm single-core wire. M single-core wire, the length of the antenna 315M is about 23cm, 433M is about 17cm; antenna position also has an effect on the reception effect of the module. The antenna position also has an effect on the module reception effect, when installing, the antenna as far as possible straight, away from the shielding body, high voltage, and interference sources. high voltage, and interference sources. When using the module, the receiving frequency, decoding mode and oscillation resistance should be matched with the transmitting frequency. The VCC voltage should be the same as the working voltage of the module, and the power supply should be filtered properly. Package include: According to your choice.
