  • ✔️ AZ-Delivery Digital Touch Sensor is a touch pad detector IC providing stable touching detection of human body and it is designed for replacing tradicional direct button key with diverse pad size. TTP223B also provides fast mode and low power mode selection by pad option (LPMB pin) and it is suitable for DC or AC application.
  • ✔️ Thanks to its low power consumption (requires 2 ~ 55V DC), small size (L x W x H): 2.4 cm x 2.4 cm x 0.7 cm, and compact design, this sensor device is perfect for various applications and Arduino projects such as: wide consumer products, waterproof electric products and button key replacement.
  • ✔️ This device is extremely easy to use: when you touch the sensor pad, the capacitance of the circuit is changed and is detected resulting in the output changing states.
  • ✔️ Touch Sensor Module can be installed upon any non-metallic materials and can have a paper thin non-metallic material covering the surface of the module.
