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. |
