Light Temp Click is a dual-channel LED driver, designed to be used in tunable Smart Connected Lighting (SCL) applications. It is based on the AL1782, a dual-channel PWM dimmable linear LED driver. By utilizing a high-frequency E-flicker free technology with Deep Dimming capability, it can be used in both single-channel dimmable white and dual-channel tunable white SCL applications. The AL1782 IC features the Adaptive Thermal Management scheme, reducing power dissipation. It also integrates an abundance of protection features for increased reliability: undervoltage, open or short circuit at the output, and thermal protection.
Light Temp Click is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.

Light Click is the add-on board which features the PD15-22CTR8 PIN photodiode, providing an effective and easy way to measure ambient light intensity. It also features the MAX6106 voltage reference and MCP3201 ADC with SPI interface. Measured ambient light intensity is sent as an analog or digital signal to the main board microcontroller. Light Click communicates through mikroBUS SPI (MISO, SCK, CS) and AN lines. The PD15-22C-TR8 is a high photosensitive light sensor with fast response time. An SMD jumper allows the user to select whether the board will be powered with a 3.3V or 5V power supply. |

LightHz Click is an accessory board in the mikroBus form factor. The board features the TSL230BR programmable light-to-frequency converter. The output can be either a pulse train or a square wave (50% duty cycle), with frequency directly proportional to light intensity. Device sensitivity is selectable in three ranges, providing two decades of adjustment. The full-scale output frequency can be scaled by one of four preset values. The board features a voltage selection SMD jumper which determines whether it will operate on 5V or 3.3V. |

Ambient 2 click carries TI's OPT3001 Ambient Light sensor. This is a small (2mm x 2mm) single-chip lux meter that measures only the visible part of the light spectrum from any kind of source (mimicking the way humans see light). It does so by filtering out 99% of infrared light. The measurement range of Ambient 2 click is from 0.01 Lux to 83k lux, and a 23-bit resolution. Communication with the target MCU is done through mikroBUS I2C pins, with an additional INT pin which can be used for triggering wake-up events (offloading the MCU). |

Ambient 4 click is a light intensity-sensing and measuring Click board™, which features an accurate, light-intensity sensor labeled as BH1721FVC, made by ROHM Corporation. It offers a high measurement accuracy in the range between 1x to 1.35x of the actual light intensity. The spectral response of the sensor is calibrated to closely match the spectral response of the human eye. Thanks to its high level of integration, the sensor requires a minimal number of external components, allowing the Click board™ to incorporate an additional level translating IC, ensuring a reliable data transfer over the industry-standard I2C interface. |

Ambient 5 click can sense the intensity of the ambient light, providing measurement data in a digital format, over the I2C interface. It utilizes the VEML6030, a miniature ambient light sensor (ALS) which occupies only 2x2 mm of space. Packed in a small transparent casing, this sensor offers a lot of features. Thanks to its 16-bit dynamic range, it can be used in very dim, but also in very bright lighting conditions. A Filtron™ technology provides spectral response close to a real human eye. The flicker noise rejection algorithm improves accuracy, while excellent thermal compensation ensures consistent readings.
Ambient 5 click is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.

An XYZ Chromatic White Color Sensor
Spectral click is a multispectral light sensing device, which uses the state-of-the-art sensor IC for a very accurate chromatic white color sensing. Spectral click provides a direct reading of the XYZ color coordinates, consistent with the CIE 1931 2° Standard Observer color coordinates. It provides mapping of the XYZ coordinates to the x, y (Y) coordinates of the two-dimensional color gamut, and it scales them to the CIE 1976 u'v' coordinate system. This click board also provides accurate Correlated Color Temperature (CCT) measurements and color point deviation from the black body curve for white light color, in u'v' coordinate system. Additionally, Spectral click features the Near-IR (NIR) wavelengths sensing channel, as well as two programmable LED channels with a constant current. |
