"TMPSII" is a car tire pressure detection system application software designed for smartphones. It is suitable for smartphones with Bluetooth 4.0 version. It cooperates with the Bluetooth sensor installed on the car to receive the pressure, temperature, and air leakage of the four tires. The tire pressure and temperature data are monitored in real time when the car is driving. When the data is abnormal, the "smart tire pressure" can be alerted in time to ensure driving safety. 【Precautions】 1. Please make sure that Bluetooth is turned on normally so that "Smart Tire Pressure" can be used normally. 2. The background voice will continue to monitor sudden tire conditions in the background. When switching to the background broadcast, it will consume more power than other operations.
