[Tire Pressure Monitoring System (TPMS)](https://en.wikipedia.org/wiki/Tire-pressure_monitoring_system) operate in the ISM Licence free bands. In USA and most of the world they use 315MHz, in Europe the frequency is 433.92MHz. The TPMS App work well with many common standards used in the automotive industry particularly from [Schrader TPMS sensors.](https://www.schradertpms.com), and this seems a common standard used in the automotive industry.
The TPMS App display is configured to display the decoded data received from the tire pressure sensors. The interval of the data being sent by each tire varies from every few seconds to minutes depending on the car and sensors, often triggered by wheel movement or rapid pressure changes. Most Schrader sensors can also be triggered to transmit data using a TPMS test tool (which transmits a signal on 125 kHz).
