Ambient 17 Click Board™

Product Code: MIKROE-5106

How Does The Ambient 17 Click Board™ Work? The Ambient 17 Click Board™ as its foundation uses the TSL2572, a high sensitivity light-to-digital converter that transforms light intensity into a digital output signal from AMS AG. The TSL2572 provides ambient light sensing (ALS) that approximates human eye response to light intensity under various lighting conditions and through a variety of attenuation materials. Accurate ALS measurements result from dual-diode technology and the UV rejection filter incorporated in the package. In addition, the TSL2584TSV can detect a wide range of precise lux measurements up to 60klx, even when mounted behind dark glass. It also has stable performance over a wide temperature range of -30°C to 70°C, suitable for measuring the present ambient light. The Ambient 17 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.

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. An interrupt is generated when the value of an ALS conversion exceeds either an upper or lower threshold. In addition, a programmable interrupt persistence feature allows the user to determine how many consecutive exceeded thresholds are necessary to trigger an interrupt. The Ambient 17 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.
