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...

HN3808-AB Rotary Encoders Features A photoelectric rotary encoder is an electromechanical device that has an internal shaft inside a cylindrical space that looks like an motor. The circular plate inside it has two slits. An optical transmitter sensor is located on one side and an optical receiver sensor is located on the other side. When a gap is placed between the two sensors, the sensors and finally the receiver are connected to the microcontroller. Rotary encoder is commonly used to determine the positio...

Liquid Level Float Switch Features The liquid level float switch is a very simple sensor that works like a switch. This sensor places vertically, floating on water. The float is located on a pipe that can move on the liquid surface. It works based on the magnetic field. Note Until you have not placed the sensor on the liquid surface, the switch is closed and when the sensor is placed on the liquid, the float moves on the pipe and goes up and the switch remains open. ...

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...

0.91 INCH OLED DISPLAY Features OLED displays are high contrast and high-resolution displays, so they provide a good readability for users. There is no backlight on OLED, and it uses independent-illuminated pixels, so, it is thinner, and more elegant in compare to LCDs. The driver chip is SSD1306, which provides I2C communication. SSD1306 is a driver module for dot-matrix display systems. It is used for common cathode type displays and is suitable for many portable applications such as mobile phones, MP3 p...

SW-520D Tilt Sensor Module Featurs A SW-520D Tilt Sensor is an electronic device that detects the orientation of an object and gives its output High or Low accordingly. Basically, it has a metallic ball inside it which moves and makes the circuit. The sensor's sensitivity is at 10 degrees tilt. This module has two output pins for each path. When tilt angle is more than 10 degree, the output is low. Note The output is on trigger mode. You can download the datasheet of this module ...

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...
