Spectra Symbol 12.7 mm Circular Force sensor
This is a force-sensitive resistor with a round, 0.5″ diameter, 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 friendly. There is a peel-and-stick rubber backing on the other side of the sensing area to mount the FSR. Just Connect a resistor to form a voltage divider and measure the voltage at the junction to find the force applied.
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.
This sensor can be easily interfaced with Microcontrollers, Arduino Boards, Raspberry Pi, etc. using an Analog-Digital Converter (ADC).

Frequently Asked Questions
1. What does a force sensor measure?
- These sensors are excellent for measuring pressure. It converts a mechanical force such as a load, weight, tension, compression, or pressure, into another physical variable, in this case, an electrical output signal that can be measured, converted, and standardized.
2. Where can I use the force sensor?
- The force sensor has applications in robotics, motion or position detection, medical devices, detecting and qualifying press, finding the center of force, detecting pressure, detecting liquid blockage, target contact detection, and pressure-sensitive touch user interface.
