The tire pressure monitoring system (TPMS) monitors the air pressure and temperature of all tires in real time through tire pressure monitoring sensors. It uses a wireless transmitter to send information such as pressure and temperature from inside the tire to the central receiver module, and then displays the data such as air pressure and temperature of each tire, and promptly issues alarms for abnormal conditions such as low pressure, high pressure, and rapid air leakage.
The development trend of TPMS sensor module technology is to develop the transmitter module towards high integration, singularization, and wireless passiveness. With the market demand for high IC integration and high reliability of TPMS products, there are already smart sensor modules that combine the sensors and MCUs required to test various physical quantities. In the next few years, we will develop modules that include three-in-one RF transmitter chips and four-in-one modules that use mechanical energy for self-power supply. By then, the tire pressure monitoring transmitter will only consist of one module and one antenna, and the customer's secondary design will become very simple.
