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: ...

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...

Double-sided Touch Sensor Features There is a wide variety of touch sensors. One of these sensors is double-sided touch sensor with 3-pin and 4-pin interface on each side. Pin N in 4-pin interface is not used. Note Pin S is always HIGH and changes to LOW if the switch is touched. (If not touched, it will be HIGH again.) Double-sided Touch Sensor Pinout This Module has 3 main pins:VCC: Module power supply – 3.3/ 5 VGND: GroundS: Sensor output (5V)N: Not us...

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...

OE-TP Light Touch Switch Module Features This module has a fingerprint sensor that can control the digital output voltage. So The output voltage will change with each touch. The operating voltage is 5 to 20 V (recommended 12 volts) and operating current is up to 3 A (peak 10 A). It also has two red and blue LEDs. The blue LED indicates the module is powered on and the red LED indicates touch detection.This type of sensor is widely used in home lighting, motor speed control, toys, etc. ...

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...

TTP229 Capacitive Touch Keypad Features Keypads are one of the most popular components that are widely used in electronics. Everybody can communicate with different systems by switches. Normally, every key occupies one digital pin of the microcontroller. But by using a 4x4 keypad you can reduce the occupied pins. With this module, you can use all 16 switches by occupying only 2 pins of the microcontroller. This 16 key capacitive touch keypad is based on the TTP229 IC. Output pins 1 to 8 are for direct swit...
