Hello,

There are three VDO senders resistive curve as following:

Temp Sender:

[℃]50 80 90 100 110 120 130 140 150
[Ω]322.8 112.5 83 62.2 47.5 36.5 28.9 23.1 18.6

Pressure Sender:
bar0 2.5 5 7.5 10 12.5 15 17.5 20 22.5 25
Ω10 32 53 73 92 109.1 125 143 155 169 184

Fuel Level:
0 1/4 1/2 3/4 1/1
3 45 85 138 180

How can i get [raw ,temp] [raw,pressure],[raw,fuel level] values for the scripting to calucate the real temperature ,pressure and fuel values?

thanks.
Terry

Hello Terry,

To find the raw values that correspond to a resistive value, and by consequence to a pressure, temperature, level, etc, you can use the reistor spreadsheet found here: viewtopic.php?f=5&t=52

Another way is to put a text gauge on a view that shows the raw input value and take samples of the actual resistive values.

Kristian,

I am still confused with this issue,

Could you give me the raw value according to the resistor when you are convenient?

thanks.
Terry

Hello Terry,

The best way to find the raw value is to use a text gauge to show the raw value and take samples using a resistor box.

If you want to calculate the values using the spreadsheet here is an example:

Fuel Level === Resistance === Raw value interpolated from column ADC1(110, 1x)
[0]==============[3]==============[30] 8 + (3-0)*(81-8)/(10-0)
[1/4]===========[45]=============[264] 243 + (45-40)*(284-243)/(50-40)
[1/2]===========[85]=============[397]
[3/4]==========[138]=============[497]
[1]============[180]=============[564]
