The module is based on a touch-sensing IC (TTP223B) capacitive touch switch module is now available at Tomson Electronics, Kochi, Kerala, India. In the normal state, the module outputs a low value, It is a low power consumption module, When a finger touches the corresponding position, the module outputs a high, if not touched for 12 seconds the module switches to low-power mode hence it is an ideal module to be interfaced with Arduino and Raspberry Pi.
Digital Capacitive Touch Switch Module is based on TTP223B. Normally,it outputs low and keeps at low power state. When a touch is sensed on the circular marked region, it outputs high and switch to the quick response state. When not being touched for 12 seconds, it switches to low power state again. If the module is mounted in the surfaces of non-metallic materials such as plastic, glass, acrylic, you can make the keys hidden in the walls and desks.
- Low power consumption
- Power supply for 2 ~ 5.5V DC
- Can replace the traditional touch of a button
- Two M2 screws positioning holes for easy installation
