Force click (Go to Parent Category)

Force click Force click is a mikroBUS add-on board with circuitry for implementing Interlink Electronics Force Sensing Resistors into your projects (with a single zone force sensing resistor included with the click).

The Force Sensing Resistor is a thin sensor made of two membranes that are separated by a spacer around the edges. When pressed, the gap between two membranes gets closed. This shorts the two membranes together, with a resistance that is proportional to applied force. The outputted analog voltage is thus a measure of force applied.

The force sensitivity range is from about 0.2N to 20N (although it depends on the implementation). Force click communicates with the target MCU through the mikroBUS AN pin. It is designed to use either a 3.3V or 5V power supply.

Stretch click
Stretch click Stretch click is a mikroBUS add-on board with circuitry for measuring stretch forces with conductive rubber cords. The click has screw terminals for connecting 2mm-diameter conductive rubber cord. The resistance of the chord increases when stretched, impacting the voltage available on the AN pin. Stretch click is designed to use either a 3.3V or 5V power supply. In a "relaxed" state, the resistance is about 130 ohms per centimeter. As you pull on it, the resistance increases (the particles get further apart). As you stretch it out, the resistance increases. So lets say you have a 15cm piece - thats about 2.1 Kohms. Stretch it to 25cm long and now it is 26/15*2.1K = 3.5 Kohms. You can stretch the rubber about 50-70% longer than the resting length, so a 15cm piece shouldn't be stretched more than 25cm. Once the force is released, the rubber will shrink back, although its not very "fast" and it takes a minute or two to revert to its original length. It's not a true linear sensor, and the resistance may vary from batch to batch, so we consider it a way to measure stretching motion but isn't really precise. One meter of conductive rubber cord and two alligator clips are included in the package.
