Le Tableau de proximité 15 Click Board™ est une carte complémentaire compacte qui contient une solution de détection de proximité à courte portée. Cette carte comprend le VL53L1, un capteur miniature de télémétrie laser à temps de vol (ToF) de pointe de STMicroelectronics. Le VL53L1 permet une mesure de distance absolue, quelle que soit la couleur et la réflectivité de la cible. Il intègre un réseau SPAD (diode à avalanche à photon unique), des filtres infrarouges physiques et des optiques pour obtenir les meilleures performances de télémétrie dans diverses conditions d'éclairage ambiant, avec une large gamme de fenêtres de couverture. Il fournit une télémétrie précise au-dessus de 4 m et peut fonctionner à des vitesses rapides (60 Hz). Grâce à des algorithmes brevetés et à une construction de module ingénieuse, le VL53L1 est également capable de détecter différents objets dans le champ de vision, de parcourir la scène et de détecter plusieurs zones.
Le Proximity 15 Click Board™ convient aux applications grand public et industrielles telles que la détection multi-objets et la numérisation multi-réseaux.
How Does The Proximity 15 Click Board™ Work?
The Proximity 15 Click Board™ as its foundation uses the VL53L1, a third-generation time-of-flight (ToF) laser-ranging sensor from STMicroelectronics. The VL53L1 brings multi-object detection and multi-array scanning, doubling the range of operation to above 4m. It also allows novel features such as multi-target detection and programmable multi-zone scanning, suitable for robotics, user detection, drones, IoT, and wearable applications.
The sensor module integrates a VCSEL that emits at a wavelength of 940nm, a processor core, and a SPAD photon detector. The addition of the optical lens system increases the photon detection rate to boost the module's ranging performance. The VL53L1 performs an entire measurement operation in as little as 5ms, and for Auto-Focus applications, the sensor detects objects twice.
The Proximity 15 Click Board™ communicates with MCU using the standard I2C 2-Wire interface to read data and configure settings, supporting Fast Mode Plus Mode up to 1MHz. It also features an intelligent interrupt function that generates every time a ranging measurement is available. Once the host reads the result, the interrupt is cleared, and the ranging sequence can repeat. Besides the interrupt pin, the Xshutdown (reset) pin labeled as XSH and routed to the CS pin of the mikroBUS™ socket optimizes power consumption used for power ON/OFF purposes. This option optimizes power consumption as the VL53L1 can be completely powered off when not used, and then woken up through the host GPIO (using the XSH pin).
The Proximity 15 Click Board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before use with 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.

Additional notes and informations
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 Proximity 15 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.
