The Inclinometer Click Board™ is a compact add-on board that offers best-in-class characteristics for inclination measurements. This board features the SCL3300, a high-performance inclinometer sensor component from Murata. The SCL3300 is a three-axis inclinometer sensor designed and manufactured for high stability, reliability, and quality requirements with angle output based on Murata's proven capacitive 3D-MEMS technology. Signal processing is performed in a mixed-signal ASIC with a flexible SPI digital interface.
This Inclinometer Click Board™ is suitable for applications demanding high stability with demanding environmental requirements such as tilt sensing, machine control, inertial measurement units, positioning and guidance systems, and many more.
How Does The Inclinometer Click Board™ Work?
The Inclinometer Click Board™ as its foundation uses the SCL3300, a high-performance best-in-class inclinometer sensor component from Murata. The SCL3300 includes an acceleration sensing element that consists of four acceleration-sensitive masses and an Application-Specific Integrated Circuit (ASIC). The sensing elements are manufactured using the Murata proprietary High Aspect Ratio (HAR) 3D-MEMS process, making extraordinarily stable and low noise capacitive sensors. Acceleration causes capacitance change that is converted into a voltage change in the signal conditioning ASIC. The SCL3300 has extremely stable output over a wide range of temperatures and vibrations.
Inclination measurement of SCL3300 is based on the angle measurements between the component and the gravity vector in a static environment. Note that no other accelerations should be present to measure angles correctly. The SCL3300 has four user-selectable measurement modes for sensor performance optimization for different applications and their requirements. Suppose the whole 360° operation is needed. In that case, the user should select either Mode 1 or Mode 2, where the limitations regarding the maximum inclination angle don't exist (inclination ranges are limited in Mode 3 and Mode 4 to maximum ±10° inclination).
The SCL3300 communicates with MCU using the standard SPI serial interface with a maximum frequency of 4MHz, and a proper logic voltage level conversion performed by the appropriate voltage level translator. The VIO logic level provides a needed reference voltage for one side of the TXB0106, a 6-bit bidirectional level shifting, and a voltage translator with automatic direction sensing from Texas Instruments. On another side of the level shifter, the reference voltage is taken from the 3.3V mikroBUS™ power rail.
The Inclinometer Click board™ can operate with both 3.3V and 5V logic voltage levels selected via the VIO SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use the SPI communication lines properly. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.

Additional Notes and Information
Depending on the development board you are using, you may need a USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
mikroSDK
The Inclinometer Click board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
