Force sensing resistor matrices are commonly referred as pressure mapping technology. 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. 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 0.2″-diameter (0.5 cm) active area, allowing you to create a sensor that is able to detect force or pressure. When no pressure is being applied to the FSR its resistance will be larger than 1MΩ. 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.

This FSR will vary its resistance depending on how much pressure is being applied to the sensing area. Interlink Electronics FSR 400 series is part of the single-zone Force Sensing Resistor family. DIY Force Sensitive Resistor (FSR): Make a force sensitive resistor (a pressure sensor) with spare parts instead of spending $5 - $20 each. 4-Simple Steps to design Force Sensing Resistor. 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. The FSR varies its resistance depending on how much pressure is applied to the sensing area. When no pressure is being applied to the FSR its resistance will be larger than 1MΩ. This is a force sensitive resistor with a square, 1.75x1.5", sensing area. 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. Figure 3: Examples of different force sensitive resistor technologies. 5 There are many volunteers that will help you. 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. Force range: 0 to 20 lb. The harder the force, the lower the resistance. 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. 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) 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) (0 to 100 Newtons) applied evenly over the 0.125 sq in surface area; Power supply: Any! Force Sensing Resistors ... FSR response is very sensitive to the distribution of the applied force. The resistance changes by applying pressure on it.Let's get started! 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. Datasheet; Interlink refers to this product as part number FSR 406 in their FSR 400 series. 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. 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. The “force sensing resistor” or FSR is not an ideal term, since it is actually sensing the pressure and the output is dependent on the pressure on the surface of the resistor. All the force sensitive resistors on Sparkfun varies from 100g-10kg, but I need it to read a force around 1kg-100kg. In general, this precludes the use of dead weights for characterization since exact duplication of the weight distribution is rarely repeatable cycle-to-cycle. It has a 5.1mm diameter active area and is available in 4 connection options. Force Sensitive Resistor 0.5in. FSRs are sensors that allow you to detect physical pressure, squeezing and weight. FSRs can differ in size, shape, and force sensing sensitivity. FSRs are two-wire devices. The resistance of FSR sensors decreases with an increase in pressure applied to its surface. ... 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 ). 4 Which pins to use depends on the library that you use and whether you use hardware SPI or soft SPI. 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). FSR® Force Sensing Resistors ... sensitive adhesive, may be cut from a film pressure sensitive adhesive, or may be built up using any combination of materials that can both separate and adhere to the two substrates.
