1 قطعة GY-SPH0645LM4H SPH0645 وحدة استشعار الميكروفون الرقمي 1.6-3.6 فولت I2S واجهة MEMS مستشعر الصوت الرقمي منخفض الطاقة ميكروفون الصوت وحدة كاشف الصوت لاردوينو راسبيري بي
الاجهزه الالكترونيات الامريكية قد تحتاج الى محمول فولت من ١١٠ الى ٢٢٠.قد تحتاج إلى محول كهرباء
مميزات خاصة
【Acts Like a Microphone】Used to receive sound waves, display vibration images of sound, but cannot measure the intensity of noise.
【Working Principle】The sensor has a capacitive electret microphone that is sensitive to sound. Sound waves cause the electret film inside the microphone to vibrate, resulting in a change in capacitance and a small voltage corresponding to the change. This voltage is then converted into A 0-5V voltage, which is accepted by the data collector through A/D conversion and transmitted.
【Specifications】50Hz-15KHz. Three digital pins: Clock, Data and Left-Right (Word Select) Clock.
【Note】This I2S MEMS microphone is bottom ported, so make sure you have the hole in the bottom facing out towards the sounds you want to read. It's a 1.6-3.6V max device only, so not for use with 5V logic.
