Force Sensitive Resistor – Long 電阻式壓力感測器 300mm

描述

Force Sensitive Resistor – Long 電阻式壓力感測器 300mm 美國 SparkFun 原裝進口

Force Sensitive Resistor – Long 電阻式壓力感測器 是使您能夠檢測物理壓力，擠壓和重量的感測器。它們易於使用且成本低廉。該傳感器是具有1/4英寸x 24英寸巨大感應區域這個非常長的力敏電阻 – 30cm – 具有0.25×24“的感應面積。根據施加到感應區域的壓力的不同而改變其電阻值，力越大，當無壓力施加到FSR時，其電阻將大於1MΩ，這個FSR可以感應在100g-10kg範圍內的任何應用力。

FSR基本上是一個電阻器，它會根據其受壓程度來改變其電阻值（以歐姆Ω為單位）。這些傳感器的成本相當低廉，易於使用，但很少準確。它們也因傳感器而異，可能相差10％。因此，基本上，當您使用FSR時，您應該只期望獲得響應範圍。儘管FSR可以檢測體重，但對於準確檢測體重是多少磅，它們是一個不好的選擇。

FSR由塑料製成，連接接線片壓接在精緻的材料上。連接它們的最佳方法是將它們簡單地插入麵包板，或使用諸如鱷魚夾，母接頭或接線板之類的夾式連接器。可以焊接到凸耳上，但是您必須非常快，因為如果熨斗的質量不好或幾秒鐘就拉開，您將熔化塑料並破壞FSR！除非您完全確定自己有技能，否則請勿嘗試直接將其焊接至FSR

Force Sensitive Resistor – Long over 300mm

This very long force sensitive resistor – over 300mm – has a sensing area of 0.25×24″. This FSR from Interlink Electronics 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. 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. 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.
