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.

MQ5 MQ 5 MQ-5 Methane LPG Liquid Propane Gas Sensor Module For Arduino are widely used in gas leakage detecting equipment in family and industry are suitable for detecting of LPG, natural gas, town gas, avoid the noise of alcohol and cooking fumes and cigarette smoke. The MQ5 ( MQ-5 ) is used in gas leakage detecting equipment in consumer and industry applications, this sensor is suitable for detecting LPG, natural gas, coal gas. Avoid the noise of alcohol, cooking fumes, and cigarette smoke. The sensitivity can be adjusted by the potentiometer. The sensitive material of the MQ-5 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exists, The sensor’s conductivity is higher along with the gas concentration rising. Please use a simple electro circuit, Convert the change of conductivity to correspond to the output signal of gas concentration.MQ-5 gas sensor has a high sensitivity to Methane, Propane, and Butane, and could be used to detect both Methane and Propane. The sensor could be used to detect different combustible gas especially Methane, it is with low cost and suitable for different application
