Descripción del Proyecto

Hi,

I am looking for a freelancer that is able to design for me a Circuit with the followings functions:

Requirements:

- 6 Analog inputs - 2 Temperature sensors ,1 humidity sensor and 3 variable resistors (designer to choose the values)

-12 Digital inputs (13DI including enable) at 8V to 15V DC

-9 Digital outputs that can drive small electromechanical relays

-One monochrome LCD that can draw a graph of temperature -(designer to choose it)

-There are no dimensions restrictions or specific parts that need to be used

-There are no restrictions on power consumption

-Power supply to be at least in this range - 8V to 15V DC

-Temperature sensors to be able to measure between -40 +70 degree Celsius

-Humidity sensor -no restrictions

-Designer to propose few Temp and Humid sensors

-Main Restriction of this project is that the product to be very very cheap to mass produce

This is the first stage of my project so I need only the Circuit Design, to be able to test it on bread board.

Second Stage will be PCB design, that will be a separate project.
