TTP223B Digital Touch Sensor capacitive touch switch module for Arduino at 375.00php
Description:
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.
Features:
Low power consumption
Power supply for 2 ~ 5.5V DC
Can replace the traditional touch of a button
Four M2 screws positioning holes for easy installation
