About this product
The TTP223 is a capacitive touch sensor that is commonly use in Arduino projects. TTP223 is a small, inexpensive sensor that can use to create a variety of touch-sensitive applications. The TTP223 sensor has a single touch sensing area of 11 x 10.5mm. When a finger or other conductive object touches the sensing area, the sensor will output a high signal. The sensor can configure to work in either active low or active high mode.
TTP223 sensor powered by a voltage of 3.3V to 5V. It has a very low power consumption of 1.5uA to 3.0uA. The sensor has a response time of 100ms to 220ms. The TTP223 sensor can use with a variety of microcontrollers, including the Arduino. There are a number of libraries available for the TTP223 sensor that make it easy to use with the Arduino.
The TTP223 capacitive touch sensor works on the principle of capacitance. Capacitance is the ability of a system to store an electric charge. When a finger or other conductive object touches the sensing area of the TTP223 sensor, it changes the capacitance of the sensor. This change in capacitance is detected by the sensor and is converted into a digital signal.
TTP223 sensor has two metal plates on the sensing area. When the sensor is not touched, the plates are separated by a dielectric material. The dielectric material is a material that does not conduct electricity. When a finger or other conductive object touches the sensing area, it bridges the gap between the two metal plates. This changes the capacitance of the sensor.
The TTP223 sensor has a built-in amplifier that amplifies the change in capacitance. The amplified signal is then passed to the output pin of the sensor. The output pin of the sensor can configure to output a high signal or a low signal.
