Capacitive Touch Sensor – 1 Channel – TTP223 Based

This Capacitive Touch Sensor is based on the TTP223 Touch sensing chip. Its design is such that it can replace the traditional direct button key with the touch based switch. Its very low power consumption and wide operating voltage range. The size of the module is also very small, thus making it easy to use it anywhere instead of conventional button.

The Capacitive Touch Sensor has pads for connection with external touch pad. Also the module has 2 different jumper connection.

Jumper A and B are for output configuration. Shorting Jumper A gives, Active Low Output, if left Open, Active High Output. Shorting Jumper B gives, toggle mode on/off, if left Open, it works as momentary On when touch.
