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.

Touch Switch Module Features
A touch sensor is a type of switch that needs to be touched by an object to operate. Touch sensors work completely similar to a switch.
Note
When this switch is touched, the output voltage will be HIGH, otherwise 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 relay or transistor to your circuit.
Note
There is a jumper on the board. If you change the status ...
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...
