Hall Current 21 Click is a compact add-on board designed for precise current measurement across a wide frequency range, ideal for fast and accurate monitoring applications. This board features the ACS37030, a galvanically-isolated current sensor from Allegro Microsystems. It provides bidirectional current sensing with a range of ±65A and a sensitivity of 20.3mV/A, offering high isolation of 3500VRMS and a working voltage of up to 840VRMS. It also features low noise and a wide operating bandwidth, making it suitable for high-speed switching current and control loop monitoring. This Click board™ is perfect for power supplies in servers, data centers, and solar DC-DC converters.
We provide a library for the Hall Current 21 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.
This library contains API for Hall Current 21 Click driver.
hallcurrent21_cfg_setup
Config Object Initialization function. hallcurrent21_init
Initialization function. hallcurrent21_read_voltage_avg
This function reads a desired number of ADC samples and calculates the average voltage level of the selected input channel. hallcurrent21_calib_resolution
This function reads the sensor voltage reference and calibrates the data resolution at a known load current. hallcurrent21_read_current
This function reads the input current level [A]. This example demonstrates the use of Hall Current 21 Click board by reading and displaying the input current measurements.
The demo application is composed of two sections :
Initializes the driver and calibrates the data resolution at 3A load current.
Reads the input current measurements and displays the results on the USB UART approximately once per second.
The measurement range is approximately: +/- 65A.
The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

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 MikroElektronika compilers.
