صلح و آزادی - سنسور فراصوتی (Ultrasonic Sensor) :

سنسور فراصوتی (Ultrasonic Sensor) :

   نوشته شده توسط: احمد زرنگ    

سنسور فراصوتی (Ultrasonic Sensor) :

تاریخچه این سنسور به سال 1912 میلادی و بعد از غرق شدن کشتی تایتانیک بر می گردد .

 بعد از غرق شدن تایتانیک دانشمندان به دنبال راه حلی برای تکرار نشدن این فاجعه افتادند ، که اگر

 کاپتان کشتی به هر دلیلی قادر به دیدن جلو کشتی نبود وسیله ای هشدار دهنده او را از وجود

 مانع مطلع سازد .

در سال 1912 میلادی آقای L F Richartson با الهام از طبیعت و استفاده از مسیریابی

خفاشها موفق به ساخت سنسور فراصوتی شد . خفاشها به دلیل بینایی ضعیف و حساس به نو

ر، از امواج فراصوتی برای تشخیص موانع استفاده می کنند .

اما از آن سال تا کنون که نزدیک به یک قرن از آن می گذرد این سنسور کاربردهای فراوانی در

 زندگی ما پیدا کرده است که به چند نمونه از این کاربردها می پردازیم .

1 . ابتدا برای نزدیک شدن بیشتر به این سنسور به معرفی آن در دزدگیر اتوموبیل و وسیله

 هشدار دهنده فاصله در اتوموبیل می پردازیم که مطمعنا همه ما کاربرد سنسور فراصوتی

را در دزدگیر اتوموبیل از نزدیک دیده ایم .

2 . سپس به کاربردهایی همچون استفاده در ثبت دقیق ترین زمان ممکنه در ورزش دومیدانی

3 . استفاده در باک هواپیما برای فهمیدن مقدار سوخت

4 . استفاده در کنترل دور ماشینهای صنعتی

5 . کاربرد در علم هواشناسی جدید

6 . و در آخر به دبی متر التراسونیک می پردازیم که امیدوارم مورد توجه شما عزیزان

 قرار گیرد .
