Bluetooth 4.0 low energy TPMS description:
It was designed as a direct tire pressure monitoring system, namely, installing pressure and temperature sensor on the tire, then displaying the real-time data on phone (Android , IOS, IPad) through Bluetooth connection, And it will alarm when the tire pressure and temperature is abnormal.
APP Program Feature:
1. Quick leak alarming：when pressure leaks over 5kpa within 5 seconds, it will start up quick leak alarming and appear a “leak” icon.
2. Slow leak alarming：when tire pressure is lower than the limited pressure, it will start up slow leak alarming and appear a ”low pressure” icon.
3. High pressure alarming：when pressure is over the limited tire pressure, it will start up high pressure alarming
4. Low pressure alarming：when pressure is lower than the limited tire pressure, it will start up low pressure alarming
5. High temperature alarming：When tire temperature is over the limited temperature, it will start up high temperature alarming
6. No signal alarming：when cannot receive signal in a certain period of time, it will start up no signal alarming
7. Low battery power alarming：When battery is lower than the setting data, it will start up low battery power alarming
