Octopus Touch PAD Sensor

Octopus Electronic Bricks, you can use them build electronics projects just as easy as piling bricks. By using Octopus electronic bricks, you may connect Arduino / Freaduino compatible boards easily with various digital, analog and I2C/Uart interfaces. These the breadboard-less firm connection are prepared to extensive modules like poteniometers, sensors, relays, servos ... even buttons, just plug and play.

Touch PAD Brick is a sensor module mainly through the capacitive touch TTP223-BA6 charge IC and the body of pressure, ceramics, glass and other dielectric materials, and the charge level is used to detect small changes in a touch switch of a sensor module.Circuit design is simple, just four operating modes. It has been widely used in induction cooker, microwave, washing machine, refrigerator, electronic scales, electronic watches, toys and other consumer products.
