TTP223B Digital Touch Sensor Capacitive Touch switch module for Arduino

Specification:

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
