Hi Robaaa, Welcome to EasyEDA. You can find a datasheet for the Sharp Optical Dust Sensor GP2Y1010AU0F here: https://www.sparkfun.com/datasheets/Sensors/gp2y1010au_e.pdf This shows you the internal schematic and the external mechanical dimensions and connectivity of the part. * You can reproduce the internal schematic from the datsheet in EasyEDA using parts from the EasyEDA Libs. * You can draw a dedicated schematic symbol for the part using `New > Schematic Lib`. * If you wish, you can also draw a dedicated PCB footprint for the part using `New > PCB Lib`. * You will also have to create a new PCB footprint for the S6B-ZR-SM4A-TF connector by JST Mfg. Co., Ltd. because this connector is not in the EasyEDA libraries. See SM4 type on p3 of this datasheet: http://www.jst-mfg.com/product/pdf/eng/eZH.pdf For the connector in the schematic, just select a `SIP6` from the drop down menu under `Connectors` in the EasyEDA Libs and then set the package type to your newly created `S6B-ZR-SM4A-TF` PCB footprint. If you have not already done so, please have a look at: https://easyeda.com/Doc/Tutorial/ This will help you get started. Note that by contributing high quality, well documented schematic or spice symbols and modules as well as PCB footprints and modules, you can earn additional private projects in EasyEDA. :)

Thanks @andyfierman let me try to create it

Do you need to be able to simulate this module or just draw it as a non-simulation schematic?

I have made: * A non-simulation schematic symbol: https://easyeda.com/andyfierman/component/GP2Y1010AU0F-Pw6420mjh * A simulation schematic symbol with a voltage control input representing the dust density: https://easyeda.com/andyfierman/component/GP2Y1010AU0F_EE-Gke7pjBhb * A demonstration simulation project: https://easyeda.com/andyfierman/Simulation_of_the_Sharp_GP2Y1010AU0F_dust_sensor_module-uhbtL3lDV Enjoy!
