TCS3200 COLOR SENSOR
- Input voltage: 2.7V to 5.5V
- Interface: Digital TTL
- High-resolution conversion of light intensity to frequency
- Programmable colour and full-scale output frequency
- No need of ADC(Can be directly connected to the digital pins of the microcontroller)
- Power down feature
- Size: 28.4×28.4mm(1.12×1.12″)
- This Arduino compatible TCS3200 color sensor module consist of a TAOS TCS3200 RGB sensor chip and 4 white LEDs. The main part of the module is the TCS3200 chip which is a Color Light-to-Frequency Converter. The white LEDs are used for providing proper lighting for the sensor to detect the object colour correctly. This chip can sense a wide variety of colours and it gives the output in the form of corresponding frequency.
This module can be used for making colour sorting robots, test strip reading, colour matching tests, etc.

- Current consumption: > 25mA (min) ~ 100mA (max)
- Dimension: 1.7cm (diameter) x 4.5cm (length)
- Cable length: 45cm
- Detection of objects: Transparent or Opaque
- Diffuse reflective type
- Sensing range: 3cm to 80cm (depends on obstacle surface)
- NPN output (normally high)
- Environment temperature: -25 °C ~ 55 °C. E18-D80 IR Sensor is widely used in robots to avoid obstacles, industrial assembly lines, Reverse Car Parking, and many other automation applications. The detection range can be adjusted according to the application using the multi-turn screw that is located at the back of the sensor. The switching signal output changes according to the obstacle detection. It remains high when no obstacles and changes to low when there are obstacles. A red LED is placed behind the probe that turns high whenever an obstacle is detected. The E18 sensor operates on 5V and consumes around 5mA to 30mA current without any load.
