Connect with Car original Fuel meter

Fuel level sensors supplied by us are resistance-type sensors with output

resistance: 0-200Ω(ohm).

For the circuit shown on the right picture, if VCC is 12V, R should be

200Ω(ohm) and if VCC is 24V then R should be 600Ω(ohm) to make the

input range to AD1 or AD2 is 0-6V.

Below formula is for calculating the fuel percentage left for this fuel level

sensor:

Percentage Left =AD value/(1024*2-AD value)*100%

Note: The value must be converted into decimal, for example, 0x0267 is

615 in decimal

Output Control

(Immediate)

Command: W******,020,P,F

Description: Send this command to control the Output of KM-2012

Note:

P=1, Output1

F=0, to close the output (open drain);

F=1, to open the output (low voltage).

Example: W000000,020,1,1
