Designing an Engine Oil Temperature Display Gauge Project

[17-CB-002]

Hi Csory,
For this CB1100 "EOT" I am confident that the resistance/voltage look-up table is accurate, so is the circuitry as described in my original posting.

Let's say that one wants to build a simple temp display with a 3 digit temperature reading and we know the following:
The constant supply voltage "VCC" is 5 volts.
The "EOT" reading is between 0.01 to 4.99 volts.
The "EOT" resistance (NTC) is 50 to 16 K Ohms.
We will temporarily back probe at the back of the "EOT" connector.
We may require a 12volt to 5 volt supply.

Note: The IAT (Intake Air temperature) is an identical circuit also.

Can you draw me the diagram & tell me what components are required?
If prototype is successful, we can get more CB1100 owners interested.

I will try to get the necessary components from my local electronic supplier to build one here in Canada.
Your assistance is appreciated.
