The module is based on a touch-sensing IC (TTP223B) capacitive touch switch module. In the normal state, the module output low, low power consumption. When a finger touches the corresponding position, the module output high, if not touched for 12 seconds, switch to low-power mode.
The TCS3200 Colour Sensor Module uses a high quality light sensor allowing you to sense any colour through a combination of Red, Green and Blue.
The module provides all of the pins of the TCS3200 on convenient 0.1″ headers – ideal for use with PCBs, breadboard or stripboard.
TTP223 Capacitive Touch Sensor Module
The TTP223 is a touch pad detector IC replicating a single tactile button.
This touch detection IC is designed for replacing traditional direct button key with diverse pad size.
