Outputs a signal if the metal part of the Sensor was touched. You can adjust the sensitivity of the sensor with the controller.
Digital Out: At the moment of contact detection, a signal will be outputted.
Analog Out: Direct measuring value of the sensor unit.
LED1: Shows that the senso..
The Sound Impact Sensor detects sound from up to 3 meters away, lending noise-activation possibilities to your project. This sensor also includes an onboard potentiometer for easy adjustment of the range of detection for the sensor. This sensor is compatible with any microcontrollers.
Touch Sensor TTP223B, single channel, Capacitive Type Switch, use with arduino and relays module to turn ON your appliances.
The Digital Sensor TTP223B Module Capacitive Touch Switch is based on a touch-sensing IC (TTP223B) capacitive touch switch module. In the normal state, the module output lo..
The touch sensor can detect the human touch by sensing the change of capacitance. The TTP223 is a touch pad detector IC which offers 1 touch key. The touching detection IC is designed for replacing traditional direct button key with diverse pad size. Low power consumption and wide operating v..
It is a great fingerprint module that communicates over TTL Serial so you can easily embed it into your next project.
The module itself does all of the heavy lifting behind reading and identifying the fingerprints with an on-board optical sensor and 32-bit CPU. All you need to do is send i..
These are very thin variable potentiometers. By pressing down on various parts of the strip, the resistance linearly changes from 100Ohms to 10,000Ohms allowing the user to very accurately calculate the relative position on the strip. Can be used as an accurate positional indicator for CNC head posi..
It is a small and low price MP3 module with an simplified output directly to the speaker. The module can be used as a stand alone module with attached battery, speaker and push buttons or used in combination with any microcontroller, Arduino or any other with RX/TX capabilities.
The Optical Finger Navigation (OFN) Module can add a unique human interface component to your microntroller projects. OFN Modules are quickly becoming popular as user input devices in many smart phones as a replacement for trackballs, which are subject to mechanical wear and tear.
2-Axis Joystick can be used to add analog input to your next project. The 2-Axis Joystick contains two independent potentiometers (one per axis) for reporting the joystick's position, with wiring options for voltage or resistance outputs.The modular form-factor allows you to plug the 2-Axis Joys..
Give your project a voice! Text-to-Speech Module is a multi-language voice synthesizer that converts a stream of digital text into natural sounding speech. Its simple command-based interface makes it easy to integrate into any embedded system.
Simply connect the Emic-2 to a 5VDC power supply, c..
