TPMS Realtime Car Tire 4 Solar Sensors Wireless Tyre Pressure Monitoring
Description:
1. 6 Alarm Modes: In order to protect the safety of driver and passengers, the TPMS tire pressure monitoring system can immediately monitor tire leakage / excessive air pressure / high temperature. With six alert modes, you can take care of your driving safety anytime, anywhere. And it is suitable for passenger cars, off-road vehicles, utility vehicles, people carriers, SUVs, people carriers and trucks.
2. Solar or USB charging: The tire pressure monitoring system receiver itself has a solar panel and a large capacity 450mAh lithium battery. The sensor battery of a car tire pressure monitoring system can last for 2 years, and both solar and usb can be recharged, so there is no need to replace the sensor battery first. The cigars box is not in the way, so it can be used normally in sunny or rainy weather.
3. Easy to install: the external TPMS buzzer sounds by sensing the temperature and pressure of four tires simultaneously. The tire pressure monitoring sensor has an IP67 rating, so there is no need to worry about driving the car under high pressure, and it is protected from rain and moisture. Know the tire pressure and tire temperature without wiring. The sensor is locked with a nut to prevent theft, so you can use the circuit with confidence!
4. Automatic vibration detection: When the engine starts, the tire pressure monitoring system detects the vibration and starts automatically. If the tire pressure monitor sensor does not detect vibration, the display will automatically enter standby mode to save power. After the product is opened, there is no need to close the product when not in use, it will automatically turn on when the car vibrates. After manually turning off the product, you must manually start it to use it.
5. Quick tip: 1. When the tire pressure monitoring system sensor does not work or the screen is off, please check whether the device has sufficient power and can be charged directly by USB. . 2. If you feel that the reading is not accurate, first check if the external sensor has power, then replace the battery of the internal button of the sensor to test.
Feature:
?…External sensor
1.Easy to install.
2.The battery life is about 2 years, and the battery can be replaced (installed in the valve core)
3.Anti-corrosion coating on the housing surface.
4.Varnished hexagonal anti-theft nut.
5.Integrated molding structure with exclusive patented silicone sealant and external tire pressure ventilation to prevent air leakage.
?…Function:
1.Real-time monitoring: Tire pressure and temperature status can be monitored whether the vehicle is running or at rest. The condition of the tires is under control.
2.High pressure / low pressure alarm: When the tire pressure is higher or lower than the set value, the system will give an alarm.
3.Air Leak Alarm: The system will give an alarm if any foreign object enters the tire and generates a leak.
4.High temperature alarm: when the tire temperature exceeds 80 ° C, the system will give an alarm.
5.Ultra-low power consumption: Extremely optimized working mode, the system battery life is up to 5 years.
6.Tire pressure sensor module operating status:
7.As the tire pressure sensing module is battery powered, the problem of battery life becomes an issue that must be considered, especially in software design. The low power implementation algorithm should be carefully designed and can be divided into the following states:
-Store State: The system is in an unused state and should go into deep sleep mode
-Transport Status: The detection module has been charged and is not actually used during transport.
-Staging state: activated carbon and started working, but stopped at this time, the speed is 0.
-Driving state: Through the acceleration sensor, the gear change is detected, the working state is entered and the tire pressure, tire temperature, speed, etc. are detected.
-Low voltage state: If the battery voltage is too low, continuing to work will cause related functions not to work properly, and a warning will be issued.
-Removal Condition: A tire leak is detected by continuous inspection, and a warning is issued.
