Force 5 Click Board

Product Description

How Does The Force 5 Click Board™ Work?

The Force 5 Click Board™ is based on the FMAMSDXX025WC2C3, a piezoresistive-based force sensor offering a digital output for reading force over the specified full-scale force span and a temperature range from Honeywell Sensing and Productivity Solutions. This sensor belongs to the group the FMA Series designed to meet the user’s need for a compensated, amplified force sensor that provides digital outputs, a variety of force sensing ranges, a small, cost-effective format, and enhanced durability and accuracy.

The flexible design of the FMAMSDXX025WC2C3 operates over a wide operating temperature range. It has a force range of 25 newtons that maximizes sensitivity and improve system resolution/performance, enhanced accuracy which includes all errors due to force non-linearity and non-repeatability, and diagnostic functions which allow the user to determine if the sensor is working correctly by detecting if electrical paths are broken or shorted inside the sensor. This Click board™ offers a very stable digital output that is directly proportional to the force applied to the mechanically-coupled sphere that enhances performance through reduced conversion requirements and the convenience of a direct interface to MCU.

The Force 5 Click Board™ communicates with MCU using the standard I2C 2-Wire interface with a maximum frequency of 400kHz. This Click board™ is easy to program because it does not require an overly demanding configuration. The code example that MikroE provides to its users consists of calibrating the sensor and displaying the diagnostic status (whether the sensor is in Normal operation, Command mode, or Stale mode). After successful calibration, the force and temperature are measured, after which the digital output data are displayed every 500 ms.

This Click board™ is designed to be operated only with a 3.3V logic voltage level. A proper logic voltage level conversion should be performed before the Click board™ is used with MCUs with different logic levels. However, the Click board™ comes equipped with a library that contains easy to use functions and an example code that can be used as a reference for further development.
