fifotrack Fuel sensor settings in Uffizio Platform

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

If the fuel tank is irregular size, the fuel level height and the fuel capacity is not linear relationship.

Calibration is needed.

In Uffizio (Trakzee) platform, you can uplaod the calibration file by selecting "Manual" option.

Below is the calibraiton file example:

Full capacity is 135 liters
