KY 002 KY-002 SW-520D Shock Vibration Switch Sensor Module for Arduino In Pakistan

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

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.

Arduino heartbeat sensor or heart rate data can be used in many Electronic design and microcontroller projects. But the heart rate data is difficult to read, however, the Pulse Sensor Amped helps us to read heart rate. The Heart Beat Pulse Sensor Amped is a plug-and-play heart-rate sensor for Arduino. It can be used by students, artists, athletes, makers, and game & mobile developers who want to easily incorporate live heart-rate data into their projects.
