YwRobot Touch Sensor Module Features Touch Sensor is used to detect human finger touch. It is known as a touch switch as well. These sensors are easy to use and useful in many projects. Before touching the sensor, the output signal is always HIGH. When a human finger touches the sensor, it will generate a LOW level signal. This module also has an LED that lights up when the sensor is touched. Note This module works in trigger mode. That is when the sensor is touched, the digital output is LOW a...

Grove Touch Sensor Features This sensor uses TTP223-B IC. When your finger approaches this sensor, the capacitance of the metal surface will change. So you don’t need to touch sensor completely. Besides, you can put this sensor under a non-metallic surface and touch it. This sensor is waterproof, and it has a variety of applications.  Note There are two red and black wire that have been connected to this sensor. If you want to increase the fingerprint sensitivity, you can remove the black w...

HTTM Series Capacitive Touch Sensor Features This touch module is available in different series with a variety of backlight colors. It features low price, high efficiency and long lifespan. The sensor part can also be placed on glass and thin plastic.Its output is on trigger mode which works like a switch. That is, when it is touched, its will be HIGH and remains HIGH until the next touch.The input voltage is 2.7 to 6 V and output pin voltage is 3.3 V. You can download t...

TTP223 Capacitive Touch Sensor Features The TTP223 sensor can be used in a wide range of applications such as smartphones and tablets. It can also detect from behind glass and thin surfaces. When a finger touches the sensor, the module output gets HIGH, and immediately switches to LOW if not touched. The operating voltage is 2 to 5.5 V. Its maximum response time is 220 milliseconds. You can download the datsheet of this module here. [wpdm_package id='19196'] TTP223 Capacitive Touch Sensor...

MicroDuino Touch Sensor Features This touch button is a simple digital output sensor. It uses the TTP223 chip to detect capacitance change. This sensor features small size, high sensitivity, long power consumption and long lifespan. When the sensor is touched, its output is LOW, otherwise it is HIGH. You can download the datsheet of this module here. [wpdm_package id='19221'] MicroDuino Touch Sensor Pinout This Module has 4 pins: VCC: Module power supply – 3.3 to 5 V GND: Ground OUT: ...

CJMCU-0201 Double Touch Sensor Features A touch sensor is a type of switch that only has to be touched by an object to operate. Touch sensors work completely similar to a switch. This sensor has two separate pads and can be used as two separate switches. Note When this switch is subjected to touch, the output voltage will be HIGH, otherwise it is LOW. Note The output current is very low (about 40 mA). If you want to connect a higher current device to this switch, you must add a rela...

4-bit Button Touch Proximity Sensor Features This module has 4 fingerprint touch inputs and 4 digital output pins. It also has 5 LEDs. One for power supply and 4 LEDs indicate fingerprint sensors. If you touch each sensor, the output becomes HIGH and the LED turns on. If you don’t touch, the output will be LOW and the LED turns off.This module can be used on glass, ceramic, plastic and other surfaces. 4-bit Button Touch Proximity Sensor Pinout This module has 6 pi...

TTP223 Capacitive Touch Sensor Features The TTP223 sensor can be used in a variety of applications such as smartphones and tablets. The sensor can recognize objects even from behind glass and thin surfaces. The operating voltage is 2 to 5.5V. The maximum response time is 220 milliseconds. This module has two non-soldered adjustment pins: A and B. The working modes are as follows:A and B both open: The default value of the output pin is LOW. When the sensor is subjected to touch, the output is HIGH, and...

TTP224 Capacitive Touch Sensor Module Features This 4 Channel Capacitive Touch Sensor Module uses the TTP224 IC and is actually a combination of 4 capacitive touch sensors. This module has 4 outputs, by touching each button from 1 to 4, the corresponding output will be High. There are also 4 LEDs on the module that will turn on by touching each button. TTP224 Capacitive Touch Sensor Module Pinout This module has 12 pins and 4 touch buttons:6 pins on the Right:OUT1: ...

MPR121 Capacitive Touch Sensor Features The MPR121 capacitive touch sensor module is a high-precision touch sensor. This module has 12 touch buttons and supports I2C communication and can be easily interfaced with any microcontroller. There is no regulator on the board, so the supply voltage should be between 1.7 to 3.6VDC.
