TTP223 Capacitive Touch Sensor

TTP223 Capacitive Touch Sensor is a very useful addition for projects or applications where a conventional mechanical button or switch is not an ideal choice. This low cost, low power module can easily add a single capacitive touch input to any of your projects. It has a working voltage range of 2V to 5.5V and hence can be used with Arduino as well as any other 3.3V microcontrollers as well.The sensitivity can be adjusted by the capacitance(0~50pF) outside.
Specifications:
Operating voltage 2.0V~5.5V ƒ
Adjustable sensitivity
Response time: 60mS
