Description: This is a small force sensitive resistor. It has a 0.16" (4 mm) diameter active sensing area. 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, with full pressure applied the resistance will be 2.5kΩ.
Two pins extend from the bottom of the sensor with 0.1" pitch making it bread board friendly.
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.

I bought two of these resistors and set them up with a particle photon to measure/monitor the milk and coffee levels at our office. Despite the difference in weight between the two, a simple adjustment in the resistance of the second portion of the circuit allowed me to easily calibrate the FSRs to the desired sensitivity. My only complaint would be that soldering leads to the pins was slightly difficult because they are so close to each other.

Its so small, I misplaced it. So I ordered three more. I will let you know when I get to try one in the next few weeks.
I have follow the guidelines to use the sensor and it works just fine. However due to lack of experience i cannot use it for my current project i’m doing. Thank you by the way and happy to have business with your team. Thank you and have a nice day.
