Car TPMS Tire Pressure Monitoring System Wireless Universal TPMS Wireless with Display for Cigarette Plug

TPMS Introductions:
TPMS is short for Tire Pressure Monitoring System. It is an electronic system for monitoring the air pressure in a vehicle tire and automatically transmitting a warning to the driver in the event of an under or over inflated tire.

Features:
1. Stable wireless signal transmission.
2. Blue LCD displayer with cigarette plug.
3. Easy-to-install TPMS, 2 minutes installation.
4. Real-time monitoring tires' pressure and temperature.
5. Sensor with long battery life (>3 yrs) and sensor battery can be easily replaced.
6. Exquisite & compact LCD screen displays pressure and temperature of 4 tires synchronously.

Functions:
Visual and audible warning for abnormal tire pressure and temperature, low pressure alarm, high pressure alarm, air leak alarm, high temperature alarm and sensor failure alarm.

Prevent tire puncture, save fuel, decrease tire wear and improving vehicle handling.

Why need TPMS?
1) Safety
Remind the driver to take measures when tires are in abnormal status to prevent accident.

2) Cost Saving
Help drivers adjust tire pressure to correct, reduce fuel consumption caused by under-inflated tires, reduce tire abrasion to extend tire life

3) Environmental-friendly
Decreases vehicle fuel consumption, less CO2

4) TPMS legislation
TPMS is an vehicle safety product that already legislated to use in US in 2007 and EU in 2012, it will be a global trend and a booming market

Working principles:
The tire pressure monitor system is made up of a CPU (Central Processing Unit) and a group of sensors. Sensors are installed inside four tires to collect the data of tire pressure and tire temperature. The data is then sent through radio electromagnetic wave to the CPU installed in the vehicle.

The tire pressure and temperature information will be displayed in the screen after being processed by the CPU. When scenarios such as tire air leakage, tire pressure too high or too low, tire temperature surpasses the alarm threshold, sensors malfunction happens, the system will alarm drivers by means of beeps and screen graph flashing. By this way, the potential problems of the tire are early warned to keep the driving safer.

Sensor technical parameters:
Working frequency: 433.92MHz
Working voltage: 2.0 ~ 3.6V
Working temperature: -40° C~+125° C
Humidity: 0%~100%
Temperature reading: ± 1° C
Pressure reading: ± 0.1Bar
Working current:
Static state: < 1uA
Emission current: < 10mA

Displayer technical parameters:
Working frequency: 433.92MHz
Working voltage: 9~15V
Working temperature: -20° C~+70° C
Working current:
Static state: < 20mA
Alarm current: < 100mA

Pressure Range of Alarm: 1.6-3.2 Bar

Air pressure Unit Conversion
1 Bar = 14.5 Psi = 100K PA = 1.02 Kgf/cm²

It can monitor the tire status during driving. Displayer will immediately alarm when any of tire is leaking, low pressure, high pressure and high temperature.

Cigarette plug displayer installation:
Plug the monitor in the cigarette lighter socket.

Sensor installation:
1. Screw the sensor onto the valve, and make sure the sensor tight with nut wrench.
2. When the display screen is power on, the TPMS will be ready to use.

During driving, every 2-minute update the data in the displayer, 10 minutes after parking, display keep still, no more data renewal. Also, when the driving speed is over 15 kilometer/hour, the display begin to renew data.
The sensor battery is RC1632 3V lithium battery, the battery's normal life is over 3 years, can be easily replaced and bought in the market.
