An SMD capacitive electret microphone with a sensitivity of 52dB is a type of electret condenser microphone that is compact and utilizes a surface-mount design. It operates based on the principle of an electret condenser, where an electret material is used as a permanently charged dielectric. This microphone type is commonly used in various applications due to its small size and general versatility.

Ch340 Arduino Mega 2560 With Cable In Pakistan
The Mega 2560 is a micro-controller board base on the CH340. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything need to support the micro-controller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get start. The Mega is compatible with most shields design for the Duemilanove or Diecimila.
The Mega 2560 is an update to the Mega, which it replaces. The Mega2560 differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the CH340 programmed as a USB-to-serial converter.
Revision 2 of the Mega2560 board has a resistor pulling the 8U2 HWB line to ground, making it easier to put into DFU mode.

The GY-271 module is based on the Honeywell HMC5883L IC for low-field magnetic sensing with a digital interface for applications such as lowcost compassing and magnetometry. The HMC5883L includes state-of-theart, high-resolution HMC118X series magneto-resistive sensors plus an ASIC containing amplification, automatic degaussing strap drivers, offset cancellation and a 12-bit ADC that enables.
Mq3 Alcohol Sensor Detector Gas Sensor Module In Pakistan
MQ3 MQ 3 MQ-3 Alcohol Detector Gas Sensor Module is a simple to use MQ-3 Alcohol Detector Gas Sensor Module which can sense the presence of Alcohol in the air. The module uses our MQ-3 sensor. It simplifies the interface to the odd pin spacing of the sensor and provides an interface through standard 4 x 0.1″ header pins. It provides an analog output corresponding to the concentration of the gas in the air and an easy to use digital output. The onboard potentiometer can be used to set the maximum gas concentration beyond which the digital output gets triggered. Just power the module with 5V set the threshold and you can start getting the gas concentration of the air around the sensor! An onboard LED signals the presence of any gas. Perfect sensing alcohol concentration on your breath just likes common breathalyzer.

Mq9 Carbon Monoxide Methane And Lpg Gas Sensor Module Price In Pakistan
MQ-9 Carbon Monoxide, Methane and LPG Gas Sensor Module can be use to sense Carbon Monoxide and Metahane Gas. Sensitive material of MQ-9 gas sensor is SnO2, which with lower conductivity in clean air. It make detection by method of cycle high and low temperature, and detect CO when low temperature (heated by 1.5V). The sensor’s conductivity is more higher along with the gas concentration rising. When high temperature (heated by 5.0V), it detects Methane, Propane etc. combustible gas and cleans the other gases adsorbed under low temperature.
