Reviewing schematic diagram

Hi I am an electronics engineer with over 28 years experience, I have done many projects with interfacing over long wires. From looking at your schematic the microcontroller would be damaged if the cable recieved a lightning strike or large ESD shock. In one of my previous jobs I designed secutiry alarm panels that had cable input runs of several hundred metres.

Hi There I have checked your project description and understand everything. I am very confident that i can do this project perfectly. Thanks

Hello, all you need for your project is proper calculations and it will work with no problem... need to know the wires you are using, and the rated current that passes into these wires to determine whether it will work or not. please contact me.

See my profile page for my experience

How r u?Bro,,Its me Imad,, Have done 200+PROJECTS REGARDING MATLAB, ARDUINO, VB.NET, PHP, HTML, PCB DESIGNING and much more. Some of the projects are as follows. 1. NEXTION LCD Based bike monitoring and Control System. 2. esp 8266 Home automation and monitoring. 3. Anti theft car system and gps locator U will feel brotherhood.

I am electrical engineer .I have lot of experience working with various employers globally. Can I do Circuit Analysis and design, Power System Analysis,DC/AC machines Electrical Distribution , translation and technical writer .i use Autocad,Matlab,Revit,Plc simulator, Pspice,word and excel.

There is a potential risk of having affected by EMI causing false triggers and also killing the nodeMCU by backEMF due to inductance caused by the long wire. If awarded I would give you a 2 page report on how to improve this and why and would also be available on Chat. Since I am on a different timezone the initial communication may see some delay.

hello, i am an electronics engineer already completed my masters in electronics engineering and have vast experience in embedded system design. i have worked with various micro controller (8051, PIC,ARM) and FPGA's(XILINX-SPARTAN 3E, ALTERA QUARTUS 2) too. i have worked on the embedded design suit - PROTEUS design suit and also has experience in working with the MULTISIM simulink circuit design software and many more. i can do your work with a minimum pay of 10$ per day rate. it will be better if we can have a detail conversation over the chat box. hope to hear from you pretty soon. thank you

You must use ground connections with screen cables for low voltage sensing. Or you can add long distance sensing circuit before the switch..

I have experience in troubleshooting and designing PCB and schematics. I have done some complex projects regarding this type of matters.
