【sparkfun的說明】
This is a force sensitive resistor with a square, 1.75x1.5", sensing area. This FSR will vary its resistance depending on how much pressure is being applied to the sensing area. The harder the force, the lower the resistance. When no pressure is being applied to the FSR its resistance will be larger than 1MΩ. This FSR can sense applied force anywhere in the range of 100g-10kg.
這是一個力感應電阻器，具有一個正方形的1.75x1.5“感應區域。該FSR會根據施加到感應區域的壓力而改變其電阻。力越大，電阻越小。對FSR施加壓力時，其電阻將大於1MΩ，該FSR可以感應100g-10kg範圍內的任何作用力。
Two pins extend from the bottom of the sensor with 0.1" pitch making it bread board friendly. There is a peel-and-stick rubber backing on the other side of the sensing area to mount the FSR.
兩個插針從傳感器的底部以0.1英寸的間距伸出，使其非常適合麵包板。在傳感區域的另一側有一個可粘貼的橡膠背襯，用於安裝FSR。
These sensors are simple to set up and great for sensing pressure, but they aren't incredibly accurate. Use them to sense if it's being squeezed, but you may not want to use it as a scale.
這些傳感器的設置簡單，非常適合感測壓力，但它們的精確度並非令人難以置信。用它們來感知是否被擠壓，但是您可能不想將其用作秤。
This force-sensing resistor (FSR) from Interlink Electronics is a passive component that exhibits a decrease in resistance when there is an increase in the force applied to the 1.5″ × 1.5″ (4 cm × 4 cm) active area, allowing you to create a sensor that is able to detect force or pressure. With a force sensitivity range of a few grams to a few kilograms, this sensor is optimized for use in human touch control applications.
來自Interlink Electronics的此力感測電阻器（FSR）是無源組件，當施加到1.5英寸×1.5英寸（4厘米×4厘米）有效面積的力增加時，電阻會減小。創建一個能夠檢測力或壓力的傳感器。該傳感器的靈敏度範圍在幾克到幾千克之間，已針對人體觸摸控制應用進行了優化。
Overview
This force-sensing resistor (FSR) from Interlink Electronics is a passive component that acts as a variable resistor, with resistance decreasing in response to increasing applied force, which makes it easy to add a touch interface to your project or create a robot with much more sophisticated tactile senses than are possible with simple lever switches. The polymer thick film (PTF) device is optimized for use in human touch control of electronic devices and can sense an applied force anywhere in the active area ranging from a few dozen grams to a few kilograms (0.2 N to 20 N).
來自Interlink Electronics的此力感測電阻器（FSR）是一種無源組件，它用作可變電阻器，隨著施加的力的增加，電阻會減小，從而可以輕鬆地為您的項目添加觸摸界面或創建具有很多功能的機器人比簡單的手柄開關更複雜的觸覺。聚合物厚膜（PTF）器件經過優化，可用於電子設備的人為觸摸控制，並且可以感應從幾十克到幾千克（0.2 N到20 N）不等的有效區域中的任何作用力。
In our tests, the resistance exceeded 1 MΩ with no applied pressure and dropped to a clearly detectable and very stable 50 kΩ with a 20 g weight placed on it. Pushing on the pad as hard as possible dropped the resistance to around 200 Ω. This resistance range is well suited to work directly with the internal pull-ups of many microcontrollers such as AVRs and PICs. The FSR was responsive enough and sensitive enough to distinctly pick up light, rapid finger taps, and it was even able to pick up the vibrations of a small vibration motor placed on it on the motor’s side.
在我們的測試中，在沒有施加壓力的情況下，電阻超過1MΩ，並在施加20 g砝碼的情況下降至清晰可檢測且非常穩定的50kΩ。盡可能用力推動焊盤，使電阻降至200Ω左右。該電阻範圍非常適合直接與許多微控制器（例如AVR和PIC）的內部上拉配合使用。FSR具有足夠的響應能力和足夠的靈敏性，可以清晰地拾取光線，快速的手指敲擊聲，甚至還可以拾取置於其側面的小型振動電機的振動。
The 1.72″ square pad is flexible, light (1.2 g), and extremely thin (0.02″), and it has an active sensing area of 1.56″ × 1.56″. It does not appreciably compress when pressure is applied. The FSR has a masked adhesive backing for easy mounting, and the 1.7″ flexible leads give you a convenient way to integrate the part into your project. The two male pins (called “solder tabs”) have a 0.1″ spacing, which means they are compatible with most solderless breadboards and perfboards, though the solder tabs are too short to work well with many 0.1″ connectors.
這個1.72英寸的方形焊盤柔軟，輕巧（1.2克），並且非常薄（0.02英寸），其有效感應面積為1.56英寸×1.56英寸。施加壓力時不會明顯壓縮。FSR具有帶掩膜的粘合劑背襯，易於安裝，而1.7英寸柔性引線為您提供了一種方便的方式將零件集成到您的項目中。兩個公引腳（稱為“焊片”）的間距為0.1英寸，這意味著它們可與大多數無焊麵包板和穿孔板兼容，儘管焊片太短而無法與許多0.1英寸的連接器配合使用。
Note that this FSR is not a load cell or strain gauge, and it is not suitable for precision force measurements. While it can be used for high-resolution dynamic measurement, only qualitative results are generally attainable. Force accuracy ranges from 5% to 25% depending on a number of factors, and the resolution is better than 0.5% of the full range. Please see the resources tab for more information, including force-vs-resistance curves, integration notes, usage tips, and suggested electrical circuits.
請注意，此FSR並非稱重傳感器或應變儀，也不適合進行精確的力測量。儘管它可以用於高分辨率動態測量，但通常只能獲得定性結果。受多種因素影響，測力精度的範圍從5％到25％，分辨率優於整個量程的0.5％。請參閱資源標籤以獲取更多信息，包括力與電阻的關係曲線，集成說明，使用技巧以及建議的電路。
