Hi,
Can you please clarify the input section and complete project requirement.
We have already done similar projects Pulse to voltage converters for industrial applications.
Small microcontroller boards with the debugging+programmer option, 12bit ADC, all for around 10$.
About us:
Micro-controllers we have worked on PIC, STM32, PSOC and AVR.
Development kits and instruments available for testing purpose.
For PCB designs we use KICAD.
C#, LABVIEW, Python for GUI, Controlling or Datalogging purpose.
Thanks and Regards,
Santosh
