What is the difference between external and internal car tire pressure monitors?

[Kristin]

Car tire pressure monitors differ in installation methods between external and internal types: external monitors have sensors installed on the outside of the tires, while internal monitors have sensors installed inside the tires. The functions of tire pressure monitoring are: 1. Preventing accidents; 2. Extending tire service life; 3. Reducing wear on the suspension system. Tire pressure monitoring automatically checks tire pressure in real-time during driving and alerts the driver to leaks or low pressure to ensure driving safety. The working principle involves an internal sensor mounted on the tire hub, which includes a bridge-type electronic pressure sensing device that converts pressure signals into electrical signals and transmits them via a wireless transmitter.
