Overview
L' Ambient 15 Click Board™ est une carte complémentaire compacte utilisée pour mesurer la quantité de lumière ambiante présente. Cette carte est équipée du TSL2584TSV, un convertisseur lumière-numérique à très haute sensibilité avec une interface I2C qui transforme l'intensité lumineuse en un signal de sortie numérique provenant d'AMS-AG. La réponse quasi-photopique du TSL2584TSV produit une mesure de lux très précise jusqu'à 33 klx même lorsqu'il est monté derrière un verre foncé. Le filtrage de la lumière infrarouge indésirable permet au capteur de mesurer la lumière ambiante avec plus de précision, produisant ainsi une réponse quasi-photopique. Il est conçu pour contrôler la luminosité dans diverses applications en fonction de la disponibilité de la lumière ambiante, de la luminosité pour une visibilité optimale et de l'efficacité énergétique. Le fonctionnement dans une plage de températures de -40 °C à 85 °C garantit un fonctionnement stable dans des conditions extrêmes. Cette carte Click™ est la plus adaptée pour obtenir des données de lumière ambiante afin de régler la luminosité dans les applications qui nécessitent des économies d'énergie et une meilleure visibilité.
La carte Click Ambient 15 est prise en charge par une bibliothèque compatible mikroSDK, qui comprend des fonctions qui simplifient le développement logiciel. Cette carte Click™ est un produit entièrement testé, prêt à être utilisé sur un système équipé du socket mikroBUS™.

How Does The Ambient 15 Click Board™ Work?
The Ambient 15 Click Board™ as its foundation uses the TSL2584TSV, a high sensitivity light-to-digital converter that transforms light intensity into a digital output signal from AMS-AG. Thanks to its near-photopic response, the TSL2584TSV can detect a wide range of highly accurate lux measurements up to 33klx, even when mounted behind dark glass. Filtering out unwanted IR light enables the sensor to accurately measure the ambient light, thus producing a near-photopic response. It also has stable performance over a wide temperature range of -40°C to 85°C, suitable for measuring the present ambient light.
The TSL2584TSV combines one broadband photodiode (visible plus infrared), one infrared-responding photodiode, and, as mentioned before, a photopic infrared-blocking filter on a single CMOS integrated circuit. Two integrating analog-to-digital converters (ADC) convert the photodiode currents into a digital output representing the irradiance measured on each channel. Integration of both channels occurs simultaneously. Upon completion of the conversion cycle, the conversion result is transferred to the Channel 0 and Channel 1 data registers. The transfers are double-buffered to ensure that the integrity of the data is maintained. After the transfer, the device automatically begins the next integration cycle.
The Ambient 15 Click Board™ communicates with MCU using the standard I2C 2-Wire interface to read data and configure settings, supporting Standard Mode operation with a clock frequency of 100kHz and Fast Mode up to 400kHz. Besides, the TSL2584TSV allows choosing the least significant bit (LSB) of its I2C slave address using the SMD jumper labelled ADDR SEL. It also possesses an additional interrupt signal, routed on the INT pin of the mikroBUS™ socket labelled as INT, indicating when a specific interrupt event occurs, such as detecting a meaningful change in light intensity.
The Ambient 15 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.
