Overview
Le Force 4 Click Board™ est basé sur le capteur de force piézorésistif HSFPAR003A d'Alpsalpine. Ce produit est un capteur de force utilisant l'effet d'un circuit de pont piézorésistif formé sur un diaphragme en silicium. Les capteurs de force piézorésistifs atteignent une linéarité supérieure à celle des autres capteurs de force.
Pour contribuer à la stabilité et à la précision, Force 4 Click Board™ comprend également le MCP1101-33, une référence de tension tamponnée de haute précision comme alimentation d'un capteur de force qui permet une stabilité et une précision élevées des lectures de tension de sortie.

How Does The Force 4 Click Board™ Work?
The Force 4 Click Board™ work in the same way as our air (atmospheric) pressure sensors, using the piezoresistive method. They detect loads (force) with a piezoresistive element manufactured using MEMS processes. Force sensors differ from air pressure sensors in that they have a thicker diaphragm, allowing detection of only relatively large changes in pressure, like from loads, while very subtle fluctuations, such as changes in air pressure, do not affect the output.

Force 4 Click utilizes an additional IC. It uses the MCP3221, a 12-bit successive approximation A/D converter (ADC) with I2C Interface, from Microchip. It is used to sample the output voltage from the sensor, providing data for the microcontroller (MCU) or some other device capable of communicating over the I2C bus. The voltage is sampled to a 12-bit value using the MCP1101-33 as the voltage reference.
If analog voltage is preferred to be red directly by the MCU, it can be easily done by adding 0 ohm resistor on J1 marked position on PCB, and the sensor output voltage will be available for reading on AN pin of mikroBUS™.
The Force 4 Click Board™ features the smallest force sensors in the industry with dimensions compact enough which makes it a perfect solution for developing a fine-diameter stylus pen.
