How do you test a force sensitive resistor?
The easiest way to determine how your FSR works is to connect a multimeter in resistance-measurement mode to the two tabs on your sensor and see how the resistance changes. Because the resistance changes a lot, a auto-ranging meter works well here.
What type of sensor is RTD?
An RTD (Resistance Temperature Detector) is a sensor whose resistance changes as its temperature changes. The resistance increases as the temperature of the sensor increases. The resistance vs temperature relationship is well known and is repeatable over time. An RTD is a passive device.
What is a sensor resistance?
A resistive sensor is a transducer or electromechanical device that converts a mechanical change such as displacement into an electrical signal that can be monitored after conditioning. They are commonly used in instrumentation. The simplest example of this is a potentiometer.
What are Force sensitive resistors ( FSR ) used for?
FSRs are sensors that allow you to detect physical pressure, squeezing and weight. They are simple to use and low cost. This is a photo of an FSR, specifically the Interlink 402 model. The 1/2″ diameter round part is the sensitive bit. The FSR is made of 2 layers separated by a spacer.
