Basic breakout board for the TEMT6000 Ambient Light Sensor. TEMT6000 is a silicon NPN epitaxial planar phototransistor in a miniature transparent mold for surface mounting onto a printed circuit board. The device is sensitive to the visible spectrum. Only what you need, nothing you don’t. Sensor acts like a transistor – the greater the incoming light, the higher the analog voltage on the signal pin.

Applications:

1. Ambient light sensor for display backlight dimming in:
2. Mobile phones
3. Notebook computers
4. PDA’s
5. Cameras
6. Dashboards

Package Includes:

1 x SparkFun Ambient Light Sensor Breakout – TEMT6000

COLOR is color recognition unit integrated with TCS3472 chipset. As the name says, COLOR is able to detect color value and return RGB data as response.

Identify color principle: The TCS3472 chipset integrated with 3 x 4 array of filtered photodiodes and a 16 bit analog-to-digital embedded converters. Out of the 12 photodiodes, 3 have red filters, 3 have green filters, 3 have blue filters and 3 have no filter (clear), which gives a total range of RGBA (RGB + Transparency)

This is a high sensitivity digital ambient light sensor module based on TSL25911, features 600M:1 wide dynamic range, detects light intensity up to 88000Lux, controlled via I2C interface, low power consumption. It is capable of operating across various light environment.

Digital light intensity sensor from Waveshare. The module is based on TSL25911 chip, which enables detection of light intensity up to 88000 lx. The dynamic range is 600M:1. It is compatible with Arduinoand Raspberry Pi and uses I2C interface to communicate with the main module. It is used when working in different lighting conditions and has low power consumption.

The TSL2591 is a very-high sensitivity light-to-digital converter that transforms light intensity into a digital signal output capable of direct I²C interface. The device combines one
broadband photodiode (visible plus infrared) and one infrared-responding photodiode on a single CMOS integrated circuit. Two integrating ADCs convert the photodiode currents
into a digital output that represents the irradiance measured on each channel. This digital output can be input to a microprocessor where illuminance (ambient light level) in lux
is derived using an empirical formula to approximate the human eye response. The TSL2591 supports a traditional level style interrupt that remains asserted until the firmware clears it

Features: 

1. Adopts TSL25911FN, measures infrared plus visible light (wider range than TSL2561)
2. Embedded ADC, direct light intensity signal output to I2C interface, less noise jamming
3. High sensitivity up to 188uLux, wide dynamic range up to 600M:1
4. Embedded infrared-responding photodiode, allows precise measuring even on strong infrared noise environment
5. Provides interrupt output with programmable upper and lower thresholds
6. Onboard voltage translator, compatible with 3.3V/5V operating voltage
7. Comes with development resources and manual (examples for Raspberry Pi/Arduino/STM32)

Package Includes:

1 x TSL25911 Light Sensor
1 x PH2.0 5PIN wire

The LTR390 is one of the few low-cost UV sensors available, and it’s a pretty nice one! With both ambient light and UVA sensing with a peak spectral response between 300 and 350nm. You can use it for measuring how much sun you can get before needing to covering up.

Unlike the Si1145, this sensor will not give you UV Index readings. However, the Si1145 does UV Index approximations based on a light level, not true UV sensing. The LTR-390, in contrast, does have a real light sensor in the UV spectrum. It’s also got a much much simpler I2C interface so you can run it on the Arduino or Python microcontrollers/microcomputers with ease. Unlike the GUVA analog sensor, the biasing and ADC is all internal so you don’t need an ADC.

To make using it as easy as possible, we’ve put the LTR390 on a breakout PCB  in our Stemma QT form factor with a sprinkle of support circuitry to give you options when testing. You can either use a breadboard or the SparkFun qwiic compatible STEMMA QT connectors, and compatibility with 5V voltage levels as commonly found on Arduinos, as well as 3.3V logic used by many other boards like the Raspberry Pi or our Feathers.

Package Includes:

1 x Adafruit LTR390 UV Light Sensor – STEMMA QT/Qwiic

Spectrometer 2 Click as its foundation uses the VD6283TX, a color sensor with advanced light flicker extraction from STMicroelectronics. It performs fast and accurate light measurements thanks to an individual ADC with a resolution of 24 bits (16 bit + 8 bit for high accuracy under low light) and a readout for six color channels: red, green, blue, IR, clear, and visible. The color channels can be individually enabled to optimize power consumption, alongside 15 programmable gains for a high-dynamic range, through a serial interface. Six channels can operate with independent, parallel reading for ALS or flicker operations, one represents a dedicated fast channel for light flicker measurement, and one stands for an internal dark channel.

The VD6283TX uses hybrid color filters with precise responses allowing accurate computation of the correlated color temperature (CCT) and Lux information. Its patented architecture and a high-performance photodiode design can also extract light-flickering frequencies from a minimum of 100Hz and a maximum frequency of 2kHz, including LED square signals, to avoid “banding effects” or check that they are safe for the human eye.

Spectrometer 2 Click communicates with MCU using the standard I2C 2-Wire interface with a maximum clock frequency of 1MHz, fully adjustable through software registers. The VD6283TX does not require a specific Power-Up sequence but requires a voltage of 1.8V for its interface and logic part to work correctly. Therefore, a small regulating LDO is used, the ADP151, providing a 1.8V out of 3.3V mikroBUS™ power rail. Since the sensor for operation requires a power supply of 1.8V, this Click board™ also features the PCA9306 voltage-level translator allowing the VD6283TX to work with 3.3V MCU properly.

This 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.

Applications: Can be used for screen brightness adjustment and white balance color assistance, lux and CCT measurement, or light frequency extraction for flicker correction assistance
