Capacitive Touch Sensor Module

This Capacitive Touch Sensor Module offers a single, momentary capacitive touch button with easy-to-use digital output pin. The onboard TTP223B touch-sensing IC monitor the sensing pad for touch. As long as a touch (e.g., from a finger) is detected, the TTP223B keeps the output line high. Otherwise, the line is kept low.

Features:

• Low power consumption
• Power supply for 2 ~ 5.5V DC
• Four M2 screws positioning holes for easy installation
• SIG pin output voltage: 3.3V or 5V, depending on the supply voltage
