Tire Pressure Sensors Installation

The tire pressure monitoring system (TPMS) has combined with two parts: sensor emitter and the receiver. Communication between the sensor and receiver is by wireless technology (433.92MHz). The receiver in the system can be our AT09 device or TPxx device, they can be work together or separately as an individual system with the sensor.
Note: the front and the rear truck tire maybe has different type of RIM. Please check the target tire you are going to install the sensor. And chose the suitable type.

Sensors Installation: TS07/09

Step 1: find the valve.


Step 2: remove the valve cap, and install the hex screw of the sensor on the valve.


Step 3: screw the sensor on the valve. And use the hex wrench to lock the sensor by the hex screw.


(Below image suitable for TS09)

Sensors Installation: TP08:

Step 1: dismounting the tire from the RIM.


Step 2: remove the original tire valve stem.


Step 3: Insert the new sensor through the valve stem hole making sure the flat side of the sensor is toward the rim, and then install the screw cap at outside.

Sensors Installation: TS10:

Step 1: dismounting the tire from the RIM, and preparing the sensor. Let metal belt come across the underneath of the sensor.


Step 2: let the metal belt across

TPMS DATA PROTOCOL

Used in RS232 | RS485| CAN| TTL | Bluetooth.
(14 bytes in length. Hex code):
00 00 AA ID ID ID ID pressureValue temperatureValue index and cell voltage CRC BB
00 00: ATA5428 bits check. 2 byte.
AA: start Tag. 1byte.
ID ID ID ID: sensor ID number. 4bytes eg.: AA BB CC DD = 0xAABBCCDD
pressureValue: 2bytes AABB = 0xAABB
temperatureValue:1byte
index and cellVoltage: 2 bytes.
index(0-15 circulate) 4bits
cell voltag 12bits. eg.: AABB: index = 0x0A cell voltag= 0x0ABB
CRC: 1byte,
BB: End Tag 1bytes

Code example in dart:
static STPMSSensor parseDataEx(List listData)
{
  STPMSSensor newData = STPMSSensor();
  int nPressure=0;
  newData.isValid = true;
  newData.strID = listData[0].toRadixString(16) + listData[1].toRadixString(16) + listData[2].toRadixString(16) +   listData[3].toRadixString(16);
  nPressure = listData[4]<< 8 | listData[5];
  if((nPressure>>4) >= 100)
  {
    newData.nPressure = (nPressure>>4) - 100; // unit: kPa
  }
  else{
   newData.nPressure = 0;
  }
   newData.nSerialID = (listData[7] & 0XF0) >> 4 ;
   newData.nBattery = ((listData[7] & 0x0F) <<8 | listData[8]) / 1000 ;
   newData.nCRC=listData[9];
  return newData;
