radar 2.0.0.0
|
Radar Click is a compact add-on board that alerts you to the presence of an intruder via interpreting the infrared radiation that emanates from their body. This board features the MM5D91-00, a presence detection sensor module that integrates 60GHz mmWave technology that counts the number of people entering or exiting an entrance from Jorjin Technologies Inc. It includes the ARM Cortex-M4F based processor system, 1Tx, 3Rx antenna, and integrated regulator, alongside azimuth and elevation field of view of ±45° and ±40°. Its detection goes up to 10m for macro and 5m for micro motion with environmental-factors immunity such as temperature, wind, sunlight, and dust. This Click board™ is suitable for various presence sensing applications, from office and home to commercial buildings and more.
We provide a library for the Radar 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 Radar Click driver.
radar_cfg_setup
Config Object Initialization function. radar_init
Initialization function. radar_default_cfg
Click Default Configuration function. radar_get_event
This function waits for an IN/OUT event or ACK command response. radar_get_temperature
This function reads the chip internal temperature. radar_set_detection_range
This function sets the min and max presence detection values. This example demonstrates the use of Radar click board by reading and parsing events as well as the module internal temperature.
The demo application is composed of two sections :
Initializes the driver and logger and performs the click default configuration.
Waits for the detection event and then displays on the USB UART the distance of detected object, accuracy, elapsed time since last reset, and the module internal temperature.
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.
