The Ambient 11 Click is a Click board™ equipped with the VEML6035, a low power, high sensitivity, I2C ambient light sensor from Vishay Semiconductors. Because of the possibilities its features offer, the Ambient 11 Click can be used as an ambient light sensor for mobile devices, industrial lighting operation, and as an optical switch for consumer, computing and industrial devices and displays.
Ambient 11 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.
The Ambient 11 Click is based around the VEML6035, which is a 16-bit low power, high sensitivity CMOS ambient light sensor operated via a simple I2C command. This sensor has many features that make it a perfect solution for small designs such as the Ambient 11 Click board™. One of these features is certainly its high level of integration that allows a minimal number of external components.
The sensor offers an active interruption feature that is triggered outside of the threshold window settings eliminating loading on the host. Besides that, VEML6035 has excellent temperature compensation to maintain output stability under changing temperature and its refresh rate setting does not need an external RC low pass filter. There is a programmable shutdown mode which reduces current consumption to 0.5 μA. Operating voltage ranges from 1.7 V to 3.6 V.
VEML6035 is a cost effective solution of ambient light sensor with I2C bus interface. The standard serial digital interface is easy to access “Ambient Light Signal” without complex calculation and programming by external controller. Beside the digital output also a flexible programmable interrupt pin is available.
Given the options its elements can offer, the Ambient 11 Click can be used as an ambient light sensor for mobile devices, industrial lighting operation, and as an optical switch for consumer, computing and industrial devices and displays.
This Click board™ is designed to be operated only with 3V3 logic level. A proper logic voltage level conversion should be performed before the Click board™ is used with MCUs with logic levels of 5V.
