Key Features
Overview
La carte Click Board™ Proximity 17 est une carte complémentaire compacte qui contient une solution de détection de proximité à courte portée. Cette carte est équipée du TMD2635, un module de capteur de proximité miniature d'AMS AG. Le TMD2635 offre une mesure de proximité avancée dans un module de réseau optique à grille terrestre minuscule et fin qui intègre un laser à cavité verticale infrarouge à émission par la surface (IR VCSEL) de 940 nm étalonné en usine pour une réponse de proximité IR. Il offre également une annulation avancée du bruit de diaphonie grâce à une large gamme de réglages de décalage via une interface I2C numérique à mode rapide pour compenser la réflexion d'énergie IR indésirable au niveau du capteur. Cette carte Click™ convient aux applications grand public et industrielles.
La carte Click Board™ Proximity 17 est supportée par une bibliothèque compatible mikroSDK, qui comprend des fonctions qui simplifient le développement logiciel. Cette carte Click Board™ est livrée sous forme de produit entièrement testé, prêt à être utilisé sur un système équipé du socket mikroBUS™.

How Does The Proximity 17 Click Board™ Work?
The Proximity 17 Click Board™ is based on the TMD2635, a miniature close-range proximity sensor module from AMS AG. The TMD2635 implements a 940nm infrared VCSEL (Vertical Cavity Surface Emitting Laser) factory calibrated for IR proximity response, alongside a digital I2C serial interface. The proximity detection feature provides object detection (e.g., close proximity) by photodiode detection of reflected IR energy sourced by the integrated VCSEL emitter. The proximity engine also features a wide range offset adjustment to compensate for unwanted IR energy reflection at the sensor. The results are further improved by automatic ambient light subtraction.
The TMD2635 does not require a specific Power-Up sequence but requires a supply voltage of 1.8V to work correctly. Therefore, a small regulating LDO is used, the MAX8511, providing a 1.8V out of both 5V and 3.3V mikroBUS™ power rails. Also, it can be shut down through software with a low standby current, allowing the power rails to remain powered at all times.
The Proximity 17 Click Board™ communicates with MCU using the standard I2C 2-Wire interface with a maximum clock frequency of 400kHz, fully adjustable through software registers with a 14-bit proximity result stored in a PDATA register. Since the sensor for operation requires a power supply of 1.8V, this Click board™ also features the PCA9306 and SN74LVC1T45 voltage-level translators. The I2C interface bus lines are routed to the voltage-level translators allowing this Click board™ to work with both 3.3V and 5V MCUs properly. Also, it uses an interrupt pin, the INT pin of the mikroBUS™ socket, used for when an interrupt occurs to alert the system when proximity result crosses upper or lower threshold settings.
The Proximity 17 Click Board™ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use the communication lines properly. However, the Click board™ comes equipped with a library that contains easy-to-use functions and an example code that can be used, as a reference, for further development.
