Inclinometer 3 Click

How does it work?

Inclinometer 3 Click is based on the SCL3400-D01, a high-performance, two-axis (XY) inclinometer sensor from Murata, employing their advanced capacitive 3D-MEMS technology for precise tilt sensing. This sensor integrates a sophisticated mixed-signal ASIC that provides signal processing through a flexible SPI digital interface, enhancing its functionality and ease of integration. Housed in a durable 12-pin pre-molded plastic casing, the SCL3400-D01 ensures consistent performance and reliability across its operational lifespan. This sensor is meticulously designed, manufactured, and tested to meet rigorous stability, reliability, and quality standards, making it exceptionally dependable across various temperatures and vibrations. Additionally, it incorporates several advanced self-diagnostic features that further bolster its operational integrity.

Ideal for applications requiring unmatched stability and accuracy in challenging environments, the SCL3400-D01 stands out with its selectable measurement modes of ±30° with a 10Hz Low Pass Filter (LPF) and ±90° with a 40Hz LPF, providing flexible deployment options. It has an ultra-low noise density and a high resolution of up to 32768LSB/g, ensuring precise and clear signal outputs under various conditions. Typical uses of this inclinometer solution include leveling, tilt sensing, structural health monitoring, and more complex applications such as inertial measurement units (IMUs) and positioning and guidance systems, where precise movement and position tracking are crucial.

As mentioned, the Inclinometer 3 Click communicates with the host MCU through a standard 4-wire SPI, capable of up to 10MHz operational frequency (2MHz is the typical frequency). Although the SCL3400-D01 is designed to operate only at 3.3V, this Click board™ also includes a TXB0106 logic level translator, which ensures the operation of this Click board™ with both 3.3V and 5V capable MCUs.

This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VIO SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, this 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.

Software Support

We provide a library for the Inclinometer 3 Click as well as a demo application (example), developed using MIKROE compilers. The demo can run on all the main MIKROE development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Inclinometer 3 Click driver.

Key functions

• inclinometer3_get_axes This function reads the accelerometer sensor axes data by using SPI serial interface.

• inclinometer3_get_temperature This function reads the temperature measurement data by using SPI serial interface.

Example Description

This library contains API for the Inclinometer 3 Click driver. The library initializes and defines the SPI drivers to write and read data from registers, as well as the default configuration for the reading accelerator and temperature data.

void application_task ( void ) 
 { 
     float temperature = 0, x_axes = 0, y_axes = 0; 
     if ( ( INCLINOMETER3_OK == inclinometer3_get_temperature( &inclinometer3, &temperature ) ) &&  
          ( INCLINOMETER3_OK == inclinometer3_get_axes( &inclinometer3, &x_axes, &y_axes ) ) ) 
     { 
         log_printf( &logger, " Accel X: %.2f mgrn", x_axes ); 
         log_printf( &logger, " Accel Y: %.2f mgrnrn", y_axes ); 
         log_printf( &logger, " Temperature : %.2f degCrn", temperature ); 
         log_printf( &logger, " ________________________ rn" ); 
         Delay_ms( 1000 ); 
     } 
 }

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.Inclinometer3

Additional notes and informations

Depending on the development board you are using, you may need 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. UART terminal is available in all MIKROE compilers.

mikroSDK

This Click board™ is supported with mikroSDK – MIKROE 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.
