Digital Capacitive Touch Sensor v2.0 Switch Module for Arduino/AVR/STM32

Highlights

• Low power consumption
• Funny and easy to use
• Alternative of traditional button
• Immersion gold process, long service life
• Based on the touch sensor chip TTP223B, the module is a capacitive touch switch module. Normally, it outputs low and keeps at low power state. When you touch the appropriate location, it will output 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,ou can make the keys hidden in the walls and desks.
