Tire Pressure Monitoring Sensors: How Do They Work?

Share Now on:

Gauging the pressure of each individual tire is necessary for your safety and your car’s performance – but not convenient at all. Luckily, TREEL’s tire pressure monitoring sensors make it easy for you to maintain the correct tire pressure for your vehicle.
Tire pressure monitoring sensors are tiny programmable electronic devices. TPMS placed in a pressurized pocket made by the car’s wheel and tire. They regularly record and monitor the tire air pressure so you can fill your tires up to the exact PSI.
The TREEL Personal tire care solution comes with a box of tire sensors with pre-assigned positions, so you know which sensor goes where. They pair with ​the intuitive TREEL CARE app, which displays real-time tire pressure metrics. Moreover, the app provides a bird’ eye view​ of your driving, insurance reminders, average fuel consumption​, and other parameters.

Are you interested in installing these sensors for your vehicle? Here’s all you need to know about tire pressure sensors and how they function.

How and Under What Circumstances Do These Sensors Issue a Warning Sign?

A TPMS alerts the driver when the tire pressure in one or more tires plummets below 25% of the recommended pressure levels. Here’s how TREEL’s TPMS technology works –

  1. The inbuilt smart sensors spot a variation in tire pressure or temperature.
  2. TREEL CARE app receives a wireless signal.
  3. The system displays an alert immediately on the screen.
  4. You can now inflate your tires to the correct pressure.

You can find the inflation pressure recommendations as well as the average tire width for different vehicle types on TREEL’s website.

How Are These Sensors Powered?

Tire pressure monitoring sensors by TREEL draw power from batteries. These batteries can last at least five years, however, as per usage, the battery life can vary. After the battery wears out, the entire sensor gets swapped out for a new one.


How Do These Sensors Work?

There exist two types of tire pressure sensors in a typical TPMS setup:

  • Direct TPMS.
  • Indirect TPMS

Direct TPMS

Direct TPMS employs individual sensors inside each tire or a full-size spare to deliver information to a central control module.
The direct TPMS system analyzes the received information. The system transmits issues with the tires to the vehicle’s information system or low-pressure light. The information is in form of a radio signal.
Since most manufacturers install the direct TPMS sensor inside the tire, replacing it gets laborious, and the user must have the entire sensor replaced.
The sensor stem and the sensor are susceptible to damage when the tire hits a curb or the vehicle meets with an accident. It must get recalibrated into the control module to ensure recognition by the vehicle’s computer every time on sensor replacement.

Indirect TPMS

Indirect TPMS does not rely on pressure sensors to monitor tire pressure. The sensors instead review wheel speed sensor data to calculate the tire size based on its rotation speed. A small tire rotates faster than a larger one, and an underinflated tire gets reduced in size than a properly inflated one.

However, this approach demands relatively greater attention.

For instance, a driver fills the tires up and checks the tire pressure before heading out on a trip. An indirect system requires resetting it every time the tires are inflated. Otherwise, will register them as a potential hazard. If you do not reset the system, it will record larger tires and might inform the driver of overinflation.

Final Words

With technological advances in the automobile sector, it has become feasible to monitor tire pressure and other parameters in real-time. Pressure sensors constantly monitor tire pressure and notify the driver of any irregularities.
There exist two types of tire pressure sensors, and you can pick either of them at your convenience. However, it is imperative that you only prefer intellectual and reliable TMPS providers like TREEL. A TREEL Sensor offers state-of-the-art features to ensure maximum safety when driving.
