Schematic
Working Prototype
Codes (Arduino Compatible)
I have more than 9 years experience in embedded hardware design with firmware development . And I have completed many projects based on esp32 . So I can do your job within a time limit with your satisfaction.
Hello,
I can give a circuit schematic using design Spark tool . No PCB design. Also I will make a prototype by purchasing all these interface modules assembled into a general purpose board and then the code. The data will be stored in the microSD card. We may have to go or ESP32 since it has more IO pins. Arduino Mega is ideal , unless you need wifi connectivity.
Note: I have included the price for the purchase of different interface boards.
Hi there, I can do all these for you. I have more than 7 years of experience in embedded product development. I can do it with great quality. let me know if you are interested.
Hello.
I hope to work with you on your project as I am very familiar with my past work.
I have over 10 years of experience in electrical engineering and PCB layout and circuit design and an electronics engineer.
I provide Supreme Quality Work against very low prices even in short deadlines.
regards.
