The Sharp distance sensors are a popular choice for many projects that require accurate distance measurements. This IR sensor is more economical than sonar rangefinders, yet it provides much better performance than other IR alternatives. Interfacing to most microcontrollers is straightforward: the single analog output can be connected to an analog-to-digital converter for taking distance measurements, or the output can be connected to a comparator for threshold detection. The detection range of this version is approximately 10 cm to 80 cm (4″ to 32″).

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.

MQ-4 Methane Natural Gas Sensor Module For Arduino in Pakistan
MQ4 High Sensitivity Gas Methane (CNG) Detector Sensor Module is a simple to use MQ-4 High Sensitivity Gas Methane (CNG) Detector Sensor Module which can sense the presence of Compressed Natural Gas(CNG), methane(CH4), etc in the air. The module uses our MQ-4 sensor. It simplifies the interface to the odd pin spacing of the sensor and provides the interface through standard 4 x 0.1″ header pins. It provides an analog output corresponding to the concentration of the gases 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.
