Force Sensitive Resistor 0.2″ Inch 5mm Diameter Small Round Circle Resistor Flexible FSR Force Sensing Resistor Passive Component DIY Electronics Project

Force Sensing Resistor 0.2’’ Diameter Circle 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).

In the tests, the resistance exceeded 1 MΩ with no applied pressure and ranged from around 100 kΩ to a few hundred Ohms as finger pressure varied from light (a few dozen grams) to heavy (pressing as hard as possible). The resistance is very stable when the pressure is fixed, and the readings are very repeatable (there are no problems with hysteresis). This resistance range is well suited to work directly with the internal pull-ups of many microcontrollers such as AVRs and PICs. Force Sensing Resistor 0.2’’ Diameter Circle was responsive enough and sensitive enough to distinctly pick up light, rapid finger taps.

The 0.3″-diameter circular pad of Force Sensing Resistor 0.2’’ Diameter Circle is flexible, light (0.15 g), and extremely thin (0.01″), and it has a circular active sensing area with a diameter of 0.2″. Force Sensing Resistor 0.2’’ Diameter Circle has a masked adhesive backing for easy mounting, and the 1.4″ flexible male 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.

Force Sensitive Resistor 1.5″ Inch 25.4mm Diameter Square Circle Resistor Flexible FSR Force Sensing Resistor Passive Component DIY Electronics Project

This force sensitive resistor has a square, 1.75×1.5″, 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.

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.

Dimension:

• Overall length: 3.5″
• Overall width: 1.75″
• Sensing area: 1.75×1.5″

Package Include:

• 1 x Force Sensitive Resistor 1.5″ Diameter Square Circle Resistor Flexible FSR Force Sensing Resistor Passive Component DIY Electronics Project
