need help in circuit design

[pepakpan]

Hello guys,

I am working on a project where I have to design a PCB. what I know is only the inputs and outputs and function of this board. so what I want is according to these I/O's what are all included in a PCB.

Inputs:
1) Analog signal 0-10V Speed
2) Analog signal 0-10V temperature
3) Signal from a level sensor
4) digital max. flowrate from pump
5) Input voltage 24V


2 outputs
- pump signal
- response signal if pump works with oil/empty

any suggestions will be appreciated

Thank you verymuch

To provide any suggestion you must provide detailed information on how you want your circuit to work.

Thankyou for the reply....

The circuit functionalities:

- Circuit will get the 2 analog signals and input power 24V. Depending on these signals the controller has to give signal to the pump. Its a piezoelectric pump.
- A signal from sensor is sent to the circuit board. It indicates low level of tank. when the sensor send this low level of tank the the controller stops functioning.
- A feedback from this pump is sent to the controller whether it is working or not

this is how it works. So what I want is which µcontroller to use and what all include in this PCB.

All well. At least I think I can conklude that you're about to find an apropriate µ-controller.

I think most µ-controller can be used for that task. Have you considering using a PLS for your task?

Hi
you may use an AVR from atmel havin ADCs

Hi guys....

Thanks for your replies. The problem is not only the µcontroller but how to interface the inputs and outputs to the µcontroller, because I have to make a PCB. Like the connection of 2 analog input signals to µcontroller. Do I need any regulators or any converters between inputs/outputs and µcontroller.

Interface depends on the µ-controller's output characteristics.

Use an AD-converter or chose an µ-controller with analog input.

You might need regulators, but again it all depends on µ-controller and characteristics of the other components around.
