For Module
1 Vcc This pin powers the module, typically the operating voltage is +5V
2 Ground Used to connect the module to system ground
3 Digital Out You can also use this sensor to get digital output from this pin, by setting a threshold value using the potentiometer
4 Analog Out This pin outputs 0-5V analog voltage based on the intensity of the gas
For Sensor
1 H -Pins Out of the two H pins, one pin is connected to supply and the other to ground
2 A-Pins The A pins and B pins are interchangeable. These pins will be tied to the Supply voltage.
3 B-Pins The A pins and B pins are interchangeable. One pin will act as output while the other will be pulled to ground.

Mq135 Air Quality Detector Sensor Module In Pakistan
The 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 gas sensor has high sensitivity to Ammonia, Sulphide and Benzene steam, also sensitive to smoke and other harmful gases. It is with low cost and suitable for different applications such as harmful gases/smoke detection
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.

PT100 Ceramic RTD Temperature Sensor Price in Pakistan
An RTD sensor (Resistance Temperature Detector) is a platinum resistance thermometer, also known as an platinum sensor or PT100 sensor. These sensors have been designed to meet the challenge of accurate temperature. PT100 RTD elements measure temperature by the change in resistance values of the platinum wires during heating or cooling.
