Dual Touch Sensor¶
Dual channel touch sensor, based on two ttp223 touch sensors. When a touch signal is detected, the corresponding pin level will be pulled low.
TTP223 is a touch pad detector IC that provides 1 touch key. The touch detection IC is specially designed to replace the traditional direct keys with different pad sizes. It features low power consumption and wide operating voltage.
Power Supply: 2.0V~5.5V
Signal Output: Digital signal
Connector: SH1.0 4P
GND - Ground Input
VCC - Power Supply Input
SIG1 - Touch signal 1, low level means touch
SIG2 - Touch signal 2, low level means touch
