Configuring sensors

Who can do it: Service provider
Where: Wialon Platform Studio

On the Sensors tab, you can configure how the platform interprets and processes data from your devices.

Sensors represent various telemetry data transmitted in device messages, such as speed, temperature, voltage and others. Configured sensors can transmit parameter values or calculation results using parameters. Depending on the data transmitted, sensors are divided into the following types:

• Acceleration: Measures the rate of change in velocity (in m/s2 or G).
• Alarm trigger: Check the alarm status (Triggered or normal)
• Battery level: Measures the tracker battery charge (in % or kWh)
• Cargo door open: Monitors the cargo door (Open or Closed)
• Door open: Monitors the door (Open or Closed)
• Driver identification: Registers the driver ID using RFID or iButton.
• Engine hours counter: Tracks the total duration the engine has been running.
• Engine temperature: Monitors the engine coolant temperature (in °C or °F).
• Fuel consumption: Measures the consumed fuel over time (in L or L/100km).
• Fuel volume: Monitors the fuel amount in the tank (in L). If your vehicle has more than one tank, you can configure a separate value for each tank using the Multiple option in the sensor template.
• Ignition: Monitors the status of the vehicle’s ignition (On or Off).
• Load weight: Measures the weight (kg or tonnes)
• Mileage counter: Tracks the total distance traveled by the vehicle.
• Private use: Monitors the status of a privacy switch or flag (On or Off).
• Refrigerator temperature: Monitors the internal temperature of a refrigeration unit (in °C or °F).
• RPM: Monitors the engine revolutions per minute.
• Seatbelt: Monitors the seatbelt status (Fastened or Unfastened).
• Tyre pressure: Measures the tyre pressure (PSI or kPa)
• Voltage: Measures the electrical system voltage in volts (V).

You can’t create new sensor types.

Each sensor type displays current value and shows a graph illustrating recent readings. This visual representation provides a quick overview of the sensor activity.

To configure a sensor, create a template within a predefined sensor type.

Sensor templates are reusable detailed configuration of telemetry parameters and formatting rules. They let you save and reuse different configurations, for example, for various device models.

To manage the device telemetry data using the Sensors tab:

1. Select a Sensor type to define which telemetry data you want to track for a specific vehicle.
2. Create a Sensor template for this sensor type to define how to calculate and format that data, using a specific formula and unit of measurement.

1. In Wialon Platform Studio, go to the Customers tab.
2. Select the customer whose devices you want to configure.
3. Navigate to the Devices tab.
4. Select a specific device from the list.
5. Click on the Sensors tab.
6. On the Sensors tab, select a sensor from the list of default sensor types, such as Engine temperature, Ignition, Refrigerator temperature. For example, Engine temperature.

The Settings panel on the right will become active, allowing you to create a sensor template for the Engine temperature sensor.

Sensor templates are reusable configurations that ensure consistency across multiple devices of the same model. You can either use an existing template or create a new one.

To select a sensor template:

1. In the Settings section, locate the Sensor template dropdown menu.
2. Click the dropdown to see a list of existing templates.
3. Select an existing template if it matches your needs.

If necessary, you can edit the existing template parameters and click Save. The changes to the template will be applied for all the customer devices.
