Please provide more information. What is the mq6 sensor? Do you mean this? https://cdn.sparkfun.com/datasheets/Sensors/Biometric/MQ-6%20Ver1.3%20-%20Manual.pdf The datasheet does not give enough information for a PCB footprint to be created. There is no dimension for the radius on which the pins are arranged and no angles between the pins. You can create your own Schematic Symbol but you will have to buy a part, measure it and then create your own PCB footprin to assign to the schematic symbol. Please read this first: https://easyeda.com/andyfierman/Welcome_to_EasyEDA-31e1288f882e49e582699b8eb7fe9b1f The Tutorial explains how to make your own symbols and footprints.

sir i am not understanding.

i want symbol of mq6 for connection with pin

You have not answered the question of exactly what the mq6 is or provided a link to a datasheet. Assuming that the mq6 is the device described here: https://cdn.sparkfun.com/datasheets/Sensors/Biometric/MQ-6%20Ver1.3%20-%20Manual.pdf then there is no Schematic symbol or PCB footprint for the mq6 in the EasyEDA library. Therefore, if you want a **Schematic symbol** then you will have to make your own as described in the Tutorial here: https://easyeda.com/Doc/Tutorial/SchematicLibs.htm#Creating-the-Schematic-Libs You can also make your own **PCB footprint** for it as decribed here: https://easyeda.com/Doc/Tutorial/PCBLib.htm#Creating-The-PCB-Libs However, if you want to make a PCB footprint for this mq6 device then you will have to buy a physical part and measure it because the datasheet for the mq6 does not give enough information for a PCB footprint to be created from the drawings. This is because there is no dimension for the radius on which the pins are arranged and no angles between the pins. Before you start trying to design a PCB using EasyEDA, you need to understand: 1. the work flow when using EasyEDA; 2. the relationship between the schematic symbols and the PCB footprints. These are both explained in: https://easyeda.com/Doc/Tutorial * Before reading this Tutorial it will help you a lot to read this first: https://easyeda.com/andyfierman/Welcome_to_EasyEDA-31e1288f882e49e582699b8eb7fe9b1f

I have now found a drawing for the mq6 LPG sensor with pin position information but it seems that there are two footprints for the same device. * Please post a link to the device you are using.
