Circuit design - temperature controller
预算 £20-250 GBP
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.
