Device Sensors

You can configure different sensors based on the device model. A single device supports up to five sensors. Once configured, a sensor’s settings can be synchronized with other devices.

General Sensor Configuration

All sensor types require the following basic information.

Parameter	Description
Sensor No.	A unique identifier for the sensor, from 1 to 99.
Sensor Name	A descriptive name, up to 20 characters.
Sensor Type	The type of sensor, such as fuel or temperature. Options vary by device.
Sensor Model	The specific model of the sensor. This is selectable after choosing a sensor type.

After filling in the details, you must click the Send button to set the peripheral ID on the device.

Sensor-Specific Configurations

The following sections detail the parameters for each sensor type.

Fuel Level Sensor

This sensor measures the amount of fuel in a vehicle’s tank.

Model	Measurement Type
MFS-U02-RS242	Liquid Level
MFS-300A-Analog	Voltage
MFS-606S-RS485	Percentage

Fuel Tank Settings

These settings are used to calculate the fuel volume based on the sensor’s readings.

Parameter	Description
Tank Shape	The shape of the fuel tank, either cylindrical or rectangular.
Fuel Type	The type of fuel, such as natural gas, gasoline or diesel.
Tank Height	The height, width, or length of the tank in millimeters.
Top Level	The highest liquid level in the tank in millimeters.
Tank Capacity	The total volume of the tank in liters, estimated from the dimensions.
Maximum Fuel	The user-defined maximum fuel volume in liters.

Calibration Settings

Calibration ensures accurate fuel readings.

Parameter	Description
Calculation Method	Choose from No Calibration (precision 1), Hydraulic Pressure (precision 0.1), or Voltage (precision 0.001).
Calibration Rules	If using hydraulic or voltage methods, you must add at least one calibration rule. This involves adding known quantities of fuel and recording the corresponding sensor values.

Load Sensor

This sensor measures the weight of a vehicle’s cargo.

Model	Measurement Type
MWS-13-Analog	Voltage

Calibration Settings

Parameter	Description
Calculation Method	Voltage (precision 0.001).
Calibration Rules	You must add at least one calibration rule by recording the sensor’s voltage values at different known loads.

Temperature and Humidity Sensor

This sensor monitors environmental conditions.

Model
MHS-7820B-RS232

Tilt Sensor

This sensor detects the angle of an object.

Model
SD23-DA01-R4

Door Sensor

This sensor detects if a door is open or closed.

Model
MBS-086

Calibration Settings

Parameter
MAC Address

CAN Bus Sensor

This sensor reads data from a vehicle’s Controller Area Network (CAN) bus.

Model
MCAN-304

Alcohol Tester Sensor

This sensor measures blood alcohol concentration (BAC).

Model
Breathalyzer‌

Calibration Settings

Parameter	Description
BAC Threshold	Set a value from 0 to 100 (unit: 1mg/100ml). If the measured BAC is equal to or greater than this value, an alert is triggered and recorded in the alcohol tester report.
Current Value	The real-time alcohol sensor sampling data (unit: mg/100ml) can be queried and supports value copying.
IMEI	The unique hardware identifier of the alcohol tester device.
Key	The device authentication key, limited to 20 characters (supports a combination of letters, numbers, and special symbols). This key must be consistent with the configuration in the alcohol tester APP and can be scanned in the settings interface.
