2 Product Introduction

2.1 Product Overview

High land surface temperature and ambient temperature could be the cause of a flat tire. When a tire is abnormal,

if you know the tire's condition in advance, you can take measures in a timely manner and thus prevent accidents.

A tire pressure sensor is used to monitor vehicle tires in real time and helps warn drivers of abnormal condition.

After it is installed on the position where tire's valve stem locates, tire pressure data will be sent to the tracker via

wireless transmitter and then is displayed on the MS03 platform or app. When the tire pressure is too low or a tire

leaks air, an alert will be generated.

2.2 Product Functions

 Monitor tire pressure and temperature in real time.

 Set the thresholds of tire pressure and temperature alerts.

 Fast air leak alert

 Radio Frequency (RF) transmission

 Smart sleep

2.4 Smart Sleep Mode

When a tire pressure sensor works normally, tire pressure data will be updated every 5 minutes by default. This

helps save power. Tire pressure data will be uploaded immediately once an alert is generated.

Each tire pressure sensor has an internal vibration module. When the sensor detects that a vehicle does not move

for 15 consecutive minutes, it will enter smart sleep mode automatically and tire pressure data will not be updated.

MEITRACK Tire Pressure Sensor User Guide

To connect the tire pressure receiver to the T333/T1, a 4-pin to 8-pin cable is required.

Plug the receiver into the 4-pin interface of the cable and plug the T333/T1 into the other side of the cable, as

shown in the following figure.

Note: Ensure that the T333/T1 is always supplied with power.

4.2 Installing a Repeater

A repeater can be installed into a truck with multiple containers.

When the tire pressure receiver cannot receive data from tire pressure sensors, you can install a repeater in the

middle of a truck to extend transmissions so that the signal can cover longer distances. Besides, you must connect

an external power supply (12 V) to the repeater.

5 Configuration

5.1 Obtaining Tire Pressure Sensor's ID

Each sensor has a unique ID number.

For example, the following tire pressure sensor's ID number is 528501, displayed on the surface of the sensor.

MEITRACK Tire Pressure Sensor User Guide

5.2 Configuring Tire Pressure Sensors by Meitrack Manager

Perform the following steps to configure tire pressure sensors:

1. Connect the tracker to a computer by USB cable and run Meitrack Manager. On the page that is displayed,

click the Tire Pressure tab.

2. On the Tire Pressure tab page, select tires to be bound, and enter the ID numbers of the corresponding tire

pressure sensors.

If you want to unbind a tire and tire pressure sensor, delete the tire pressure sensor's ID number.

3. Set the thresholds of high pressure, low pressure, and high temperature alerts, as shown in the following

figure.

You can set alert thresholds based on the type and condition of vehicles. The tire pressure of large trucks is

7–12 bar, while the tire pressure of private cars is 2.2–2.5 bar. In high temperature environments, if you drive

a vehicle for a long time, the tire temperature can reach more than 80°C . As the outside air temperature

increases, the tire pressure will increase.

Use a large vehicle as an example. Bind four tires to four tire pressure sensors, set the high pressure thresholds to

12 bar and low pressure thresholds to 7 bar, and set the high temperature threshold to 85°C , as shown in the

previous figure.

Note: If the tire pressure receiver is not installed properly, you will fail to configure tire pressure sensors.

5.3 Configuring Tire Pressure Sensors by MS03 Platform

Before configuring tire pressure sensors, you should:

1. Set the server IP address and port on Meitrack Manager.

2. Ensure that the tracker is online on the MS03 tracking platform.

Perform the following steps to configure tire pressure sensors:

1. On the main interface, choose Management.

2. On the Management window that is displayed, select Parameter settings from Use Normal. The Parameter

settings window will be displayed.

3. Select a tracker and click the Tire pressure tab.

4. On the Tire pressure tab page, select tires to be bound, and enter the ID numbers of the corresponding tire

pressure sensors.

If you want to unbind a tire and tire pressure sensor, delete the tire pressure sensor's ID number.

As shown in the previous figure, four tires have bound to four tire pressure sensors. You can move the horizontal

scroll bar to bind the tires of four trailers.

5. Click the Tire alarm tab. On the tab page that is displayed, set the thresholds of high pressure, low pressure,

and high temperature alerts, as shown in the following figure.

Note: If you use Meitrack Manager to configure tire pressure sensors, you must connect the tracker to a computer

by USB cable. If you use the MS03 platform, you must ensure that the tracker is online. However, the two

configuration methods are nearly the same.

5.4 Configuring Tire Pressure Sensors by MS03 App

5.4.1 Obtaining MS03 App

Scan the following QR code to download the MS03 app.

6 Data Querying

6.1 Querying Tire Pressure Data by MS03 Platform

On the main interface, choose Reports > Historical data.

When a tracker is online, you can query related historical data as follows.

Besides the high pressure, low pressure, and high temperature alerts, there are the following alerts:

 When the decrease rate of tire pressure exceeds 0.2 bar/s, a fast air leak alert will be generated.

 When the decrease rate of tire pressure is between 0.05 bar/s and 0.2 bar/s, a slow air leak alert will be

generated.

 When the increase rate of tire pressure exceeds 0.2 bar/s, a tire inflation alert will be generated.

 When tire pressure sensor's power is too low, a low power alert will be generated. Please replace the battery

with a new one.

You can also view tire pressure data on the graphical interface.

1. On the main interface, choose Reports > Event Report. On the Event report page that is displayed, select a

tracker and event, set query time and click . Then select a report and double-click it.

2. On the page that is displayed, a red area indicates that an alert is generated, and a black area indicates no

alert is generated.

3. Move the mouse to a red area, the alert details will be displayed.

6.2 Querying Tire Pressure Data by MS03 App

1. On the main interface, choose Reports > History.

MEITRACK Tire Pressure Sensor User Guide

2. On the page that is displayed, enter the IMEI number, device name or user name, set the query time, and

click Confirm. The History page will be displayed.

3. On the History page that is displayed, click Check. The Tire detail page will be displayed.
