This example is based on fifotrack S20 model.
All S/A series vehicle GPS tracker models' AD1 are the same way.
Analog input 1 (AD1) connected with AS10 capacitive fuel sensor
Fuel tank type: regular size shape (irregular size fuel tank is another way)
Full fuel capacity: 75 liters
Step 1: Find the object, double click, click "sensors" and configure
Connection Type: AD input1
Connected Sensor: Fuel Level
Click "Calibration" for next step
Step 2: Fill the Calibrtion menu
Sensor output unit: choose "voltage"
Conversion factor: always is "1"
Tank Capacity: fill the actual fuel tank full capacity, unit is liter. In this case is 75 liters
Below three lines are always same constant value
Empty Tank Reading: 0
Half Tank Reading: 2.048
Full Tank Reading: 4.096
Background knowledge: the fuel sensor's output voltage is 0-5V, but the GPS tracker device converts the voltage 0-5V to 0-4096 and uploads it to the platform. Uffizio treat this 0-4096 AD value as direct voltage 0-4.096V
After settings check the result
