نقد و بررسی اجمالی
.برای راه اندازی آسانتر
این سنسور کافیست از ماژول اندازه گیری فشار استفاده شود FSR402 یک سنسور مقاومتی حساس به نیروی فشار یا FSR است. قطر ناحيه حساس سنسور 12.7ميليمتر است. مقاومت الکتریکی این FSR متناسب با میزان فشار اعمال شده به این ناحیه
حساس تغییر خواهد کرد. هر چه مقدار نیروی وارد آمده بیشتر شود مقاومت الکتریکی
کمتر خواهد شد. در حالتی که نیرویی به سنسور وارد نمی شود مقاومت آن بالاتر از
10مگا اهم خواهد بود. و
در بیشترین مقدار فشار مقاومت الکتریکی نهایتا به 200 اهم خواهد رسید.
استفاده از این سنسور
بسیار ساده است. کاربرد آنها بیشتر برای تشخیص وجود نیرو و اندازه گیری تقریبی شدت
آن است، لذا این سنسورها برای محاسبه دقیق مقدار نیرو طراحی نشده اند. به بیان
دیگر این سنسورها برای تقریب نیروی وارد شده بر یک جسم مناسبند اما نمیتوانید با
آن یک ترازوی دیجیتال طراحی کنید. در رباتیک برای تشخیص لحظه رسیدن گیره ربات به
اجسام یا زمان رسیدن پای ربات به زمین از این سنسورها استفاده می شود. با قابلیت تشخیص نیروهای ضربه ای تکرار شونده.

Introduction
FSR is a sensor, so
that you detect the physical pressure, squeezing and weight. They are simple to
use and low cost. This is a photograph of FSR, the following model is 402. 1/2
circle diameter portion is sensitive bits.

FSR separated by two layers, as the pressure increases, these points
will touch the active semiconductor elements, so that the resistance becomes
small

FSR can be seen as a resistor to change its resistance value by the size
of the pressure of the resistance (in ohms Ω) depends on how much repression.
These sensors are relatively low cost and easy to use, but they are rarely
accurate. They variety, differences in performance of only about 10%. So
basically when you use the FSR, you should only expect to get a response about
the range. Although FSR can detect the weight, but to get to choose their
specific weight data is not possible.

However, for most of the touch-sensitive applications, such as
“This is squeezed or pushed much”, they are a good choice, because of
the high cost!

Test FSR
The easiest way to test how your FSR work, first with a multimeter, connect two
pins of the sensor and by squeezing the hand to observe how the change in
resistance. Because of the large change in resistance, auto ranging meter can
easily test it out. Before you “give up” test, make sure you try
collected from 1 ohm and 100 ohm trillion different ranges.
