Mikroe Force 4 Click features the Alpsalpine HSFPAR003A piezoresistive force sensor that uses the effect of a piezoresistive bridge circuit formed on a silicon diaphragm. Piezoresistive force sensors achieve higher linearity than other force sensors. The Force 4 also includes the MCP1101-33, a high precision buffered voltage reference, to help with stability and accuracy. The MCP1101-33 is a power supply to a force sensor that allows high accuracy of output voltage readings.
