KY 027 KY-027 Magic Light Cup Sensor Module for Arduino In Pakistan

The AD8232 Single Lead Heart Rate Monitor is a cost-effective board used to measure the electrical activity of the heart. This electrical activity can be charted as an ECG or Electrocardiogram and output as an analog reading. ECGs can be extremely noisy, the AD8232 Single Lead Heart Rate Monitor acts as an op-amp to help obtain a clear signal from the PR and QT Intervals easily. The AD8232 is an integrated signal conditioning block for ECG and other bio-potential measurement applications. It is designed to extract, amplify, and filter small bio-potential signals in the presence of noisy conditions, such as those created by motion or remote electrode placement.

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.

MQ8 MQ 8 MQ-8 Hydrogen Gas Sensor Module For Arduino H2 Alarm Detection MQ-8 Sensor Hydrogen Gas Sensor Module H2 Alarm Detection use in clean air low conductivity tin oxide (SnO2). When there is an environment in which the combustible gas sensor, conductivity sensor with increasing concentration of combustible gases in air increases. Using a simple circuit to convert the change in conductivity of the gas concentration corresponding to the output signal. MQ-8 hydrogen gas sensor of high sensitivity, the monitoring of the other hydrogen-containing gas is also very satisfactory. This sensor can detect a wide range of hydrogen gas, city gas, in particular, is a low-cost sensor for a variety of applications.
