The TSL Luminosity Sensor Breakout is a sophisticated light sensor which has a flat response across most of the visible spectrum. Unlike simpler sensors, the TSL measures both infrared and visible light to better approximate the response of the human eye. And because the TSL is an integrating sensor (it soaks up light for a predetermined amount of time), it is capable of measuring both small and large amounts of light by changing the integration time. The TSL is capable of direct I2C communication and is able to conduct specific light ranges from k+ Lux easily. Additionally, the TSL contains two integrating analog-to-digital converters (ADC) that integrate currents from two photodiodes, simultaneously. Each breakout requires a supply voltage of 3V and a low supply current max of 0.6mA.

TCS Color Sensor is a complete color detector, including a TAOS TCS RGB sensor chip and 4 white LEDs. The TCS can detect and measure a nearly limitless range of visible colors. Applications include test strip reading, sorting by color, ambient light sensing and calibration, and color matching, to name just a few.  The TCS has an array of photodetectors, each with either a red, green, or blue filter, or no filter (clear). The filters of each color are distributed evenly throughout the array to eliminate location bias among the colors. Internal to the device is an oscillator which produces a square-wave output whose frequency is proportional to the intensity of the chosen color.  Specifications Single-Supply Operation (2.7V to 5.5V) High-Resolution Conversion of Light Intensity to Frequency Programmable Color and Full-Scale Output Frequency Power Down Feature Communicates Directly to Microcontroller S0~S1: Output frequency scaling selection inputs  S2~S3: Photodiode type selection inputs OUT Pin: Output frequency OE Pin: Output frequency enable pin (active low), can be impending when using Support LED lamp light supplement control Size: 28.4x28.4mm Recognition color principle of sensor To TCSD, when choose a color filter, it can allow only one particular color to get through and prevent other color. For example, when choose the red filter, Only red incident light can get through, blue and green will be prevented. So we can get the red light intensity. Similarly,when choose other filters we can get blue or green light. TCSD has four photodiode types. Red, blue, green and clear, reducing the amplitude of the incident light uniformity greatly, so that to increase the accuracy and simplify the optical. When the light project to the TCSD we can choose the different type of photodiode by different combinations of S2 and S3. Look at the form as follows. The TCS Color Sensor TCSD can output the frequency of different square wave (occupies emptiescompared 50%),different color and light intensity correspond with different frequency of square wave. There is a relationship between the output and light intensity. The range of the typical output frequency is 2HZ~500KHZ. We can get different scaling factor by different combinations of S0 and S1. Look at the form as follows. The TCS Color Sensor Connection Diagram The TCS Color Sensor If you want to turn on the LEDs on the board, you could connect the led pin to 5v or a digital pin to drive them.
