The TCS3200 / TCS230 is a 8-pin SOIC surface mount package color detection / recognition sensor which has an array of photodiodes. To detect color, the photodiodes are arranged in groups of four with red, green, or blue filters on three of the photodiodes and no filter on the fourth. This allows the sensor to measure the amount of red, green, blue, and white light that hits the sensor.

This module incorporates four white LEDs to illuminate an object of which you wish to measure the color of. The white light from these LEDs hits your test object and reflects back to the module's sensor, which then measures the amount of red, green, blue, and white light that was reflected.

Typical output frequency range of the sensor from 2 Hz ~ 500 kHz, users can also select two programmable pins to 100%, 20% or 2% of the output scale factor, or power-off mode. Output scale factor so that the output of the sensor can be adapted to different measurement range and increases its ability to adapt. For example, when using a low-speed frequency counter, you can choose a small scaling value that TCS230 output frequency and counter match.

As is, this module is susceptible to ambient light. We recommend creating a shroud to keep ambient light out of the test area or use the sensor in a dark area with little ambient light to get better results.

This module does fit on a standard breadboard, but it spans the width of the standard prototyping pins, requiring connecting wires to be connected to the breadboard under the module.

RM12.60

This touch sensor module is a capacitive touch-type touch switch module based on a touch detection IC (TTP223) on a capacitive pad. This module can be easily used with microcontrollers like Arduino to act as a touch input. It can replace the boring push button with touch pads and is also easy to use.


Normally, the module outputs a low level and the mode is a low-power mode. When touching the corresponding position with your finger, the module will output high level and the mode will switch to fast mode. When there is no touch for 12 seconds, the mode switches to low power mode again.

The module can be installed on the surface of non-metallic materials such as plastics and glass. In addition, thin paper (non-metal) is covered on the surface of the module. If the touched position is correct, it can be hidden in the wall, desktop, etc. button. This module allows you to avoid the troubles of conventional press buttons.
 
FEATURES

  • Inching type: the initial state is low, the touch is high, not touched low (similar to the touch button function)
  • Low power consumption
  • Power supply could be 2~5.5V DC
  • Both sides could be used as a touch surface, which can replace the traditional touch keys
  • 4 M2 screw holes for easy installation

SPECIFICATIONS

  • Operating Voltage: 2V to 5.5V
  • No. of channel: 1
  • Output high: 0.8*Vcc
  • Output low: 0.3*Vcc
