Description: 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 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.

is the 1.5 square inchs available, how much it does cost? i really want to buy it, for my university project ( azfar, 22/10/2017 )
Hi, we are sorry, we only have this size only.
Hi, if i follow the "SN-FRC-0.5 Getting Started Guide" to construct my circuit, do I need to include any op-amp like LM324? Do I need to amplify anything? ( Joey, 01/03/2016 )
Hi, Refer to getting started guide, you only need 10K pull-down resistor only. But it is depend to your application. Thanks. :)
How to calibrate a force sensitive resistor? ( TAN CHEW LING, 16/12/2015 )
Hi, You can refer to FSR integration guide that can be download from "Attachment" tab at product page. For further inquiry, kindly visit our technical forum as this session is only for short inquiry. Thanks. :)
Hi,want toask when will be the FSR restock again? ( Melvin Joel, 27/11/2015 )
Hi, The Sensor will be ready after 1 Week
Hello, want to ask when the FSR will be restock again? ( Melvin Joel, 26/11/2015 )
Hi, The sensor will be ready after 1 week. Thanks.
If the pushing object is bigger than the 0.5 inch sensing area.... still able to measure the force given? ( see jia fung, 05/11/2015 )
Hi, This FSR will vary its resistance depending on how much pressure is being applied to the sensing area.Thanks :)
Hi, any pressure/force sensor that can effort human weight up to 100kg/150kg? Thanks ( Ruiqi, 18/08/2015 )
Hi, we do not have any sensor that can effort human weight up to 100kg/150kg.
Hello. When will it be restock? ( Dean, 29/06/2015 )
Hi, it will ready after 1-2 Weeks.
Hi, when this stock will be restock again? ( wong, 05/05/2015 )
Hi, The stock will be ready after 1-2 Weeks.
Hello, where i can find the resistor network and amplification diagram?tnks ( Claudio, 25/03/2015 )
You can download the "FSR Integration Guide" under Attachment in the product page.
