A force sensitive resistor circuit is extremely useful in various electronic projects. The force sensitive resistor by Soshine donating the effort to determine how much pressure is being applied. Let’s find out a little about how it works, and then we’ll see how you use it in your projects.
A force sensitive resistor (FSR) is a special type of resistor whose resistance varies based on the amount of pressure applied to it. When you push down on an FSR, its resistance decreases, letting more electricity to flow through. Measuring the change released into the boat, it's possible to determine how much pressure was exerted.
If you have been playing with microcontrollers and sensors, you will most likely needed to measure the force or pressure applied on a particular device or place on an object. By wiring the FSR to a circuit with a microcontroller or other electronics, you can measure and log exactly how much force is being applied. This is desirable for applications such as making a touch-sensitive button or a pressure-sensitive mat.
You may also need to test that FSR before you use it in your project to ensure it generates good readings. You could do this by applying a known force and recording the resistance values. This will allow you to derive a correct formula to describe force. To test the FSR refers to testing how it responds to various amounts of strong and make sure it’s working properly.
To improve measuring force with an FSR circuit, you can incorporate additional components such as an Operational Amplifier or a Voltage Regulator. These parts can condition the signal of the FSR to be stronger and less noisy and thus provide a more accurate reading. With carefully designed circuit, this module can better sensitivity and accuracy can be compared with conventional gas sensors.
FSR circuits can be applied in many novel ways. They can be used to measure grip strength in medical devices or to help robots to sense obstacles. FSR circuits have applications in interactive art, e.g., to create touch-sensitive surfaces. The flexibility of FSR circuits means they can be used for any project where force or pressure has to be measured.
