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 0.58″-diameter (1.5 cm) active area, allowing you to create a sensor that is able to detect force or pressure. (0 to 100 Newtons) applied evenly over the 0.125 sq in surface area; Power supply: Any! This FSR will vary its resistance depending on how much pressure is being applied to the sensing area. This small, round force sensing resistor is similar to our most popular FlexiForce sensor (A201), but it is offered at a length of 1 inch (25.4 mm). Force Sensing Resistors ... FSR response is very sensitive to the distribution of the applied force. Force sensitive resistor #164027. Force sensing resistor matrices are commonly referred as pressure mapping technology. The greater the force, the lower the resistance. By Kasper86 - Tue Oct 01, 2013 12:19 pm - Tue Oct 01, 2013 12:19 pm #164027. FSRs are two-wire devices. If there's a datasheet, you'll want to refer to it Size: square, ... connects through a 200 to 1000 ohm resistor to the first pin on the IR sensor. How to Use a Force Sensitive Resistor - Arduino Tutorial: In this tutorial you will learn how to use an FSR - Force Sensitive Resistor with Arduino to fade an LED. The resistance changes by applying pressure on it.Let's get started! Post a datasheet for the FSRs. ... For example, the Interlink 402 says in its datasheet that its accuracy is within 2% of its resistive value, and changes with time at a rate of 5% * log 10 ( days ). We have seven versions of force-sensing resistors available, which lets you choose the one with the dimensions that best suit your application: Similar to our other force sensors, the A301 allows you to capture accurate compression measurements at a low cost and easily integrates with an Arduino. Force Sensitive Resistor (FSR) Created by Ladyada Last updated on 2013-07-30 05:15:18 PM EDT. Adafruit Industries, Unique & fun DIY electronics and kits Round Force-Sensitive Resistor (FSR) [Interlink 402] ID: 166 - FSRs are sensors that allow you to detect physical pressure, squeezing and weight. Force range: 0 to 20 lb. If RFSR and RM are swapped, the output swing will decrease with increasing force. 4-Simple Steps to design Force Sensing Resistor. When no pressure is being applied to the FSR its resistance will be larger than 1MΩ. Force sensing resistors can be designed as single-point force sensors, or in a matrix array form, allowing the user to capture pressure distribution over a given area. Uses less than 1mA of current (depends on any pullup/down resistors used and supply voltage) Datasheet (note there are some mathematical inconsistancies in here) This site uses cookies to store information on your computer. Force Sensing Resistor® FSR® 400 Series Data Sheet In the shown configuration, the output voltage increases with increasing force. This sensor is a variable resistor just like a photocell or flex sensor. Force dependent on actuation interface, mechanics, and m determine centroid of force Detect presence, position, or motio of a person or patient in a bed Active 3 years, 3 months ago. Force-sensitive resistors (FSRs) Force-sensing (or force-sensitive) resistors (FSRs) are two-legged variable resistors that decrease in resistance with an increase in applied force.

FSR 400 Series Square Force Sensing Resistor Description Interlink Electronics FSRTM 400 series is part of the single zone Force Sensing ResistorTM family. Force sensing resistors, or FSRs, are robust polymer thick film (PTF) devices that exhibit a decrease in resistance with increase in force applied to the surface of the sensor. Newark offers fast quotes, same day shipping, fast delivery, wide inventory, datasheets & technical support. FSRs are sensors that allow you to detect physical pressure, squeezing and weight. This is a force sensitive resistor with a round, 0.5" diameter, sensing area. In the datasheet of FSR A401 of FlexiForce ( here ), it is mentioned that "measurement ranges of 0-1 lb and 0-7000 lb are achievable with the A401 sensor by utilizing the recommended circuitry. Buy FSR01CE - Ohmite - Force Sensitive Resistor, FSR Series, 20 g to 5 kg, Square, Connector Housing. DIY Force Sensitive Resistor (FSR): Make a force sensitive resistor (a pressure sensor) with spare parts instead of spending $5 - $20 each. For those soldering to the force sensitive resistor, you would need to solder at a lower temperature and ensure that the soldering iron is not heating the tab for no more than 1 second. Uses less than 1mA of current (depends on any pullup/down resistors used and supply voltage) Datasheet (note there are some mathematical inconsistancies in here) They are simple to use and low cost.
