The Air Velocity Click Board™ is a compact add-on board that measures direct airspeed. This board features the FS3000-1005, a surface-mount type air velocity module utilizing a MEMS thermopile-based sensor from Renesas. This I2C-configurable air velocity module features a digital output with a 12-bit resolution with a wide operational range of 0-7.2meter/second (0-16.2mph). The sensor comprises a “solid” thermal isolation technology and silicon-carbide coating to protect it from abrasive wear and water condensation. This Click board™ is suitable for air handling systems, HVAC, analytic gas monitoring systems, data centres, and air quality systems to detect failures in the fan or blower, fan speed control, or filter clogging.
The Air Velocity Click Board™ is supported by a mikroSDK-compliant library, which includes functions that simplify software development. This Click board™ comes as a thoroughly tested product, ready to be used on a system equipped with the mikroBUS™ socket.
How Does The Air Velocity Click Board™ Work?
The Air Velocity Click Board™ is based on the FS3000-1005, a high-performance surface-mount type air velocity module utilizing a MEMS thermopile-based sensor from Renesas. The FS3000-1005 measures the direct local air, which allows the system control to make adjustments quickly. It features a digital output with a 12-bit resolution with a wide operational range of 0-7.2meter/second (0-16.2mph). By providing a closed-loop control, systems can reduce the energy cost of the system. The FS3000-1005 targets low-profile applications and is designed to measure airflow around critical components such as analytic gas monitoring systems, data centers, and air quality systems to detect failures in the fan or blower, fan speed control, or filter clogging.
The FS3000-1005 comprises a "solid" thermal isolation technology and silicon-carbide coating to protect it from abrasive wear and water condensation. This Click board™ communicates with MCU using the standard I2C 2-Wire interface to read data and configure settings, supporting a Fast Mode operation up to 400kHz. It continuously measures in operation, where the data is sent in byte packages.
The Air Velocity Click Board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used as a reference for further development.

Software Support
We provide a library for the Air Velocity Click Board™ as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
The package can be downloaded/installed directly from NECTO Studio The package Manager(recommended), downloaded from our LibStock™ or found on MikroE Github account.
Library Description
This library contains API for Athe Air Velocity Click Board™ driver.
Key functions
-
airvelocity_read_outputThis function reads the raw output counts by using I2C serial interface. -
airvelocity_convert_counts_to_mpsThis function converts raw output counts to velocity in m/sec (0-7.23).
Example Description
This example demonstrates the use of the Air Velocity Click Board™ by reading and displaying the output counts and air velocity in m/sec.
void application_task ( void )
{
uint16_t out_counts;
if ( AIRVELOCITY_OK == airvelocity_read_output ( &airvelocity, &out_counts ) )
{
log_printf ( &logger, " Out counts: %urn", out_counts );
log_printf ( &logger, " Air velocity: %.2f m/srnn", airvelocity_convert_counts_to_mps ( out_counts ) );
Delay_ms ( 250 );
}
}
The full application code, and ready to use projects can be installed directly from NECTO Studio The 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.AirVelocity
Additional Notes and Information
Depending on the development board you are using, you may need USB UART Click Board™, 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 MikroElektronika compilers.
MIKROSDK
The Air Velocity 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.
