To add sensors do next:

1. Go to Settings menu located in top panel,

2. Choose object and click on edit object button.

3. In Edit object window go to Sensors tab.

4. In left bottom corner press button.

5. Sensor properties window will appear.

Important! Refer to sensor parameters section for more details.

Sensor

• Name - sensor name.

• Type - sensor type that is suitable for the specific task. Note: for correct sensor type refer to GPS device user manual.

  • Digital input - displays device sensor value 1 or 0 (enables input fields to enter sensor state text).

  • Digital output - displays device sensor value 1 or 0 (enables input fields to enter sensor state text).

  • Driver assign - this sensor type allows to receive string from RFID or iButton devices. Received string will be checked in system. As a result, information will be seen, which driver is using vehicle. Note: Auto assign must be set in object settings.

  • Engine hours - receives engine hours value.

  • Fuel level - this option requires to specify result type (value or percentage) depending on device information result. For more details refer to GPS device user manual.

  • Fuel consumption - receives total fuel consumption or consumption between two points.

  • Ignition (ACC) - displays device sensor value 1 or 0 (enables input fields to enter sensor state text).

  • Odometer - receives total odometer or odometer between two points.

  • Passenger assign - this sensor type allows to receive string from RFID or iButton devices. Received string will be checked in system. As a result, information will be seen, which passenger is using vehicle. Note: Auto assign must be set in object settings.

  • Temperature - receives temperature value.

  • Trailer assign - this sensor type allows to receive string from RFID or iButton devices. Received string will be checked in system. As a result, information will be seen, which trailer is connected to vehicle. Note: Auto assign must be set in object settings.

  • Custom - allows to enter any necessary sensor information. For more details refer to GPS device user manual.

• Parameter - sensor parameter, refer to sensor parameters section for more details.

• Data list - sensor will be shown in popups on map.

• Popup - sensor will be shown in object details panel.

Result

• Type - option depends on chosen sensor type.

  • Logic - allows to enter text depending on sensor value.

  • Value - this option requires to specify result units of measurement (for example: kg, liters...) and formula (if applicable).

  • Percentage - this option requires to specify result lowest and highest values.

  • Absolute - total value.

  • Relative - value between location points.

• Units of measurement - value depending on sensor type (example: liters, gallons, volts...)

• If sensor "1" (text) - allows to show custom text if result value is 1 (example: if sensor is used to monitor engine state, than if engine is running, text could be ON).

• If sensor "0" (text) - allows to show custom text if result value is 0 (example: if sensor is used to monitor engine state, than if engine is not running, text could be OFF).

• Formula - in some cases need to perform device result calculations to get precise value. Note: for more details refer to your GPS device user manual. In formula field you can multiply, divide, add, subtract, use brackets. X means value which was sent by device.

Depending on sensor and result type parameters you will be able to enter lowest and highest values. This option allows to configure value range. Example: if need to monitor vehicle fuel level and GPS device is sending volts instead of real capacity, we need to know voltage of empty and full fuel tank (example: empty tank: 3 volts, full tank: 10 volts, according to these values: lowest value: 3, highest value: 10).

• Lowest value - lowest sensor value.

• Highest value - highest sensor value.

• Ignore if ignition is off - in some cases this solves fuel level drops when vehicle is not running.

Calibration

This section can be used with Fuel level, Temperature and Custom sensor type. Calibration allows you to set precise parameters of the sensor. Widely used to calculate fuel tank readings or convert sensor voltage to temperature values.

Example 1: Fuel tank

Different places Inside of the fuel tank may be wider or narrower and to get more accurate data you should use calibration.

In order to perform a more precise measurement of fuel tank, it is necessary to measure fuel tank sensor voltage width different fuel level. The system allows you to set up to 50 points, the more points you specify, the more accurate readings you will get.

Directions: Drain the fuel tank, write down the fuel sensor voltage readings, fill the tank with 5 liters/gallons of fuel, make a note of the fuel sensor voltage readings and so on until the tank is full.

Program will calculate fuel amount according to fuel sensor values.

Example of fuel sensor results:

• Empty tank - 2 volts

• 5 liters tank - 3 volts

• 10 liters - 4 volts

• 15 liters - 5 volts

• ...

• 60 liters - 14 volts

Follow these steps to enter data correctly:

• Choose sensor type: Fuel level

• Choose result type: Value

• Enter units of measurement: liters or gallons

• In calibration X field: 2

• In calibration Y field: 0

• Click add button

• In calibration X field: 3

• In calibration Y field: 5

• Click add button

• In calibration X field: 4

• In calibration Y field: 10

• Click add button

• ...

• Save sensor

Example 2: Temperature sensor

If temperature sensor sends volts instead of temperature values, then it is possible to convert results.

In this case we need to know temperature sensor voltage at its lowest and highest states.

• -40 degrees - 3 volts

• 40 degrees - 7 volts

Program will calculate exact temperature according to set values.

Follow these steps to enter data correctly:

• Choose sensor type: Temperature or Custom

• Choose result type: Value

• Enter units of measurement: (according to example, you should use degrees)

• In calibration X field: 3

• In calibration Y field: -40

• Click add button

• In calibration X field: 7

• In calibration Y field: 40

• Click add button

• Save sensor

Dictionary

Dictionary allows to assign text to particular parameter value. Text will be visible in object details panel and popup which appears on map.
