MAX9814 Microphone Amplifier Module In Pakistan
The MAX9814 is available in the space-saving, 14-pin TDFN package. This device is specified over the -40°C to +85°C extended temperature range. MAX9814 is a low-cost, high-quality microphone amplifier with automatic gain control (AGC) and low-noise microphone bias. The device features a low-noise preamplifier, variable gain amplifier (VGA), output amplifier, microphone-bias-voltage generator, and AGC control circuitry. The low-noise preamplifier has a fixed 12dB gain, while the VGA gain automatically adjusts from 20dB to 0dB, depending on the output voltage and the AGC threshold. The output amplifier offers selectable gains of 8dB, 18dB, and 28dB. With no compression, the cascade of the amplifiers results in an overall gain of 40dB, 50dB, or 60dB. A trilevel digital input programs the output amplifier gain. An external resistive divider controls the AGC threshold and a single capacitor programs the attack/release times. A trilevel digital input programs the ratio of attack-to-release time. The hold time of the AGC is fixed at 30ms. The low-noise microphone-bias-voltage generator can bias most electret microphones.

Arduino Sensor And ModulesFingerprint Scanner GT-511C3 Bio-Metric Sensor Module In Pakistan
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.

WTV020SD-16P music module Mp3 Module For Arduino in Pakistan
The WTV020SD is a small, simple IC for embedding audio playback into your next project. These devices are commonly used in children’s toys and talking retail displays. This breakout board allows you to access the functionality of the WTV020SD to give a voice to your next project. The breakout board includes a battery connector and a micro-SD card slot. Simply load your audio files onto a micro-SD card and plug it in, power up the module, and trigger the playback. Playback can be triggered in either key or serial mode: The key-mode provides a stand-alone operation where a host micro is not required. With only 3 push buttons, a 3V battery, and a speaker, an extremely compact and low component count MP3-Player-like system can be implemented. The serial mode provides a simple, 2-wire interface to any micro-controller via its DATA and CLK lines. Audio operations such as PLAY, PAUSE, STOP, and VOLUME control functions are all available to the host micro via simple serial commands. The audio compression used in this module is a little strange (4-bit ADPCM @ 6-32kHz) so you’ll need to download the utility in the documents below in order to convert yours. WAV files into the 4-bit ADPCM format required.

MQ135 Air Quality Detector Sensor Module in Pakistan
The MQ135 MQ-135 MQ 135 Air Quality Detector Sensor Module For Arduino has lower conductivity in clean air. When the target combustible gas exists, the conductivity of the sensor is higher along with the gas concentration rising. Convert change of conductivity to the corresponding output signal of gas concentration. The MQ135 MQ-135 MQ 135 gas sensor has a high sensitivity to Ammonia, Sulphide and Benzene steam, also sensitive to smoke and other harmful gases. It is at low cost and suitable for different applications such as harmful gases/smoke detection.
