Bluetooth 4.0 TPMS DescriptionIt 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 Feature1. 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.Technical Parameter1. Operating voltage: 3V 2. Operating currant: 300UA 3.
