Arduino Sensor And Modules

ECG Electrodes with Metal Snap and Low Impedance Solid Medical Conductive Gel Disposable ECG electrodes are used for diagnostic ECG or ECG monitoring They can be used for various ECG tests Chunfeng and reg; Disposable ECG electrodes use an AG/AgClsensor element and solid conductive and adhesive Hydro-gel for adhesion The AG/AgCl sensor element has the best sensitivities and the solid conductive and adhesive hydro-gel has very low impedance and is non-irritating, non-sensitizing and non-cytotoxic to the skin All electrodes are latex-free.

The GT511C3 GT-511C3 GT 511C3 FPS (fingerprint scanner) is a small embedded module that consists of an optical sensor mounted on a small circuit board. The optical sensor scans a fingerprint and the microcontroller and software provide the functionality of the module which automatically processes the scanned fingerprint. The GT511C3 GT-511C3 GT 511C3 Optical Fingerprint Scanner Module with JST SH Connector is a high-performance fingerprint scanner. This optical sensor module is designed for easy integration into applications with a serial interface (UART). The GT-511C3 is a TTL fingerprint scanner and can be accessed by Raspberry Pi, Arduino, or any other Microcontroller using just two wires viz Tx & Rx.GT-511C3 Fingerprint Scanner module has an onboard optical sensor and a 32-bit CPU. It does most of the heavy work like reading and identifying fingerprints. A simple set of commands has to be sent from your micro-controller and the GT-511C3 fingerprint scanner does the rest of the work. To get started, just register each fingerprint that you want to store by sending the corresponding command and pressing your finger against the reader three times. The fingerprint scanner can store different fingerprints and the database of prints can even be downloaded from the unit and distributed to other modules. As well as the fingerprint “template,” the analyzed version of the print, you can also retrieve the image of a fingerprint and even pull raw images from the optical sensor. We need two wires are for TX and RX and two wires for the power supply (5V). The module can be used in projects for identifying users, for example allowing access through a door by scanning a finger instead of using a key.

HC-SR04 HC SR04 Ultrasonic Sensor also called HCSR04 Ultrasonic Range Finder. Ultrasonic Sensor module HCSR04 provides a 2cm – 400cm non-contact measurement function, the ranging accuracy can reach 3mm. The modules include ultrasonic transmitters, receivers, and control circuits.

The mounting Bracket Holder Stand is specifically designed for the HC-SR04 Ultrasonic Sensor Module. With this ultrasonic sensor, you can attach the le to your application such as small robots or DIY projects very quickly and conveniently. This best mount bracket is made from good quality Acrylic. This mounting holder has mounting holes of a diameter of 3.8mm. Use this Arduino distance measuring sensor to easily attach your ultrasonic distance sensor to your robots, onto a servo for panning, and anywhere else you’d like. 90 degree mounting with 3 screw holes at the base and 4 screw holes for the ultrasonic sensor itself.
