Types of TTP223 capacitive touch sensors

The TTP223 capacitive touch sensor is a widely used sensor in the consumer electronics industry. It comes in two main types: the single touch and the multi-touch sensor.

• Single Touch Sensors

  A single touch sensor can detect one area touched on the PCB at a time. The TTP223B chip on the sensor board works like a switch with an inner delay. When the users touch the sensor plate, the chip detects the capacitance change and turns on the output. The output stays on as long as the plate is touched. Once the plate is released, the output switches off after a 0.5-second delay. The touch plate then returns to the idle state. Users can set the sensor for either active high or active low output. Makers can use single touch sensors for applications where only one area needs to be touched at a time, like in lightning switches or alarm systems.

• Multi-Touch Sensors

  They have several areas considered sensor electrodes. Unlike the single sensor, the multi-touch can detect more than one area touched at a time. The multi-touch sensor works by measuring the capacitance change in the different electrodes. When there is a change in one, the sensor can identify which one. The design allows for the identification of the touched areas when activating the output. These types of sensors are mostly used in strong touch environments. They are suitable for applications like smart screens, multiplayer games, or wherever a quick response to several touch points is needed.

Besides these two main types, TTP223 sensor modules are made in different designs to improve fitting and mounting flexibility. Some come in ultra-small sizes to conserve PCB space, especially in thin gadgets. Others have a lower profile so they can be mounted on the case surface without raising the area around the sensor. The waterproof sensors are ideal for use in environments exposed to moisture damage, like kitchen appliances. These variants widen application possibilities for TTP223 sensors.

Functions and Features

The function of a capacitive touch sensor is to detect the presence and location of a touch or near touch of an electrically conductive object like a human finger. The main functions of the TTP223 Capacitive Touch Sensor IC are to detect and measure capacitance and to provide an output signal when the sensor is touched. The output signal is a change in voltage that indicates that the output is either high or low. The output voltage is dependent on the state of the touch. There are some main features of the sensor, including:

• Stable and Reliable: The IC is a stable, reliable touch sensor. It replaces mechanical switches that are less reliable and more susceptible to failure due to physical wear and tear.
• Touch Sensitivity: The sensor has high touch sensitivity, and touching the metal pad can activate the sensor. It is important that there is good sensitivity even in environments with noisy conditions.
• Replacing Mechanical Switches: The TTP223 Capacitive Touch Sensor IC can replace mechanical switches and pushbuttons. It does this by providing a non-mechanical switch that is more reliable with time and usage.
• Two Output Modes: There are two output modes for the sensor, and they are both logic high and low. The output can be either low or high, depending on the state of the touch. The two output modes are for either momentary or toggle functionality.
• Time-Out Period: There is a time-out period of 10 seconds when a finger touches the pad. During the time-out period, the output will be low if the finger is not on the pad. The design prevents chattering in the output due to noise.
• Power Supply Voltage: The power supply voltage of the touch sensor ranges between 2.0 volts and 5.3 volts. This range is good for most electronic devices.
• GPIO Interfacing: The sensor can easily connect to any microcontroller GPIO pin. It is suitable for a wide range of microcontrollers, including the ARM, AVR, and PIC families.

Applications of ttp223 capacitive touch sensor

The TTP223 capacitive touch sensor can be installed in numerous applications, some of which are highlighted below:

• Metal surfaces: Since the TTP223 sensor can detect capacitance, it is suitable for applications where the switch is mounted on a metal surface. The sensor can be used in numerous places, such as the automotive and industrial sectors, where devices are regularly mounted on metal attires. Furthermore, it can be incorporated in areas that need protection or devices that touch power-sensitive surfaces, like electrical devices.
• Outdoor environments: People use capacitive touch sensors in outdoor environments exposed to moisture, such as fountains and weather stations. Since the TTP223 sensor has a protective surface layer, it can be used under such conditions, hence preventing wear and tear damage to the system.
• Industrial machines: Industrial machines with rotating parts mostly utilize touch sensors in their on/off switches or in areas where frequent touch is required. The TTP223 sensor can be activated in machines with rotating parts to keep them moving. This reduces physical contact with the moving machine parts, making operation safer.
• Automated doors: TTP223 touch sensors can be incorporated into the buttons on doors that people need to press to get through or on light beams that, when interrupted, trigger door closing as a safety measure against door slamming.
• Consumer electronics: This touch sensor is suitable for use as a power switch in consumer electronic devices such as video game controllers, mp3 players, and mobile phones.
• Medical equipment: Since the TTP223 sensor is sensitive to touch, it can be applied in medical devices located in hospitals, clinics, and home care settings. Devices such as bedpad sensors, electronic thermometers, and digital weighing machines can all be equipped with the sensor. It helps in the activation of buttons and/or screens for various functions like taking readings, changing settings, and powering the device on and off.

Besides these applications, the TTP223 capacitive touch sensor can be adopted in a variety of devices, including alarm systems, toys, lighting systems, and kitchen appliances.
