ITPMS

A lightweight, energy-efficient Improved TPMS with integrated tire wear assistant (ITPMS). Designed for universal compatibility and precision.

🔥 Key Features

• 🏋️ Ultra-Compact Design
  Minimal weight (<30g) ensures compatibility with most tires without affecting balance.

• 📡 Autonomous Operation
  Wakes up via accelerometer motion detection → close to none battery drain when stationary.

• 📊 Fast And Precise
  Uses device computing from sensors such as:

  • Pressure sensor
  • Temperature sensor (built into the MCU)
  • 3-axis accelerometer
  • Hall effect sensor

• 🔋 10-Year Battery Life
  Has low-powered elements and works only while the vehicle is moving.

• 🎯 Hall Effect Initialization
  Quick pairing with magnetic TPMS initializing pen.

🛠 How It Works

Installation & Activation

1. Open remove the tire from the rim.
2. Mount the TPMs on the stem valve inside the tire .
3. Wake & Pair the TPMs with the magnetic TPMS initializing pen.
4. Drive to see the real time pressure and temperature changes.

Data Transmission

Trigger	Action
> 5% pressure deviation from last read	Instant RF alert to ECU
> 5% temperature deviation from last read	Instant RF alert to ECU
10s without any significant changes	Keep-alive ping

🔑 Setup

Assistant

Run this command to download the needed dependencies:

pip install -r .requirements.txt

After that you can run the UI with:

python Assistant/TireAssistantGUI.py

TPMS & TPMs

The software must be flashed on a special TPMs via SPI programmer. From there you have to follow the steps in Installation & Activation an you will be ready to use it.
