Solar LCD Car TPMS SP370 Wireless Tire Pressure Monitoring System with 4 Sensors
Description:
- Tire pressure alarm, wireless transmission; four wheel simultaneous monitoring on the color display
- Prevent problems before they occur: prevent puncture and air leak to balance air pressure, save fuel, and reduce wear
- With 4 external/internal sensors
External sensors
- Easy to install
- The battery life is about two years, and the battery can be replaced (installed on the valve core)
- Anti-corrosion coating on the surface of the casing
- Hexagonal nut anti-theft patent
- Patented silicone integrated molding structure with unique external tire pressure sealing and ventilation to prevent air leakage
Internal sensors
- The battery life is about five years, and the battery can be replaced (replace the original valve core, balance after installation).
- Aeronautical road alloy gas nozzle
- Quality battery
- The casing is made of nylon chemical fiber to prevent corrosion
- An adjustable angle link between the nozzle and the sensor ensures that the angle is adjusted to be flush with the edge of the wheel
- Professional installation is recommended
Tire pressure sensor module working state
Because the tire pressure detection module is powered by battery, the battery life problem becomes a problem that needs to be considered, especially in software design. The low-power algorithm implementation should be carefully designed and can be roughly divided into the following states:
- Storage status: The system is in an unused state and it should enter deep sleep mode
- Transportation status: The detection module has been loaded and is not actually used during transportation.
- Parking status: Activated and started working, but stopped at this time, the speed is 0
- Driving status: Through the acceleration sensor, the speed change is detected, the running state is entered and the tire pressure, tire temperature, speed, etc are detected.
- Low voltage status: If the battery voltage is too low, continuing to work will cause the related functions not to work properly, and a warning will be issued.
- Leakage condition: A tire leak is detected by continuous inspection, and a warning is issued.
Feature:
- High-efficiency solar panel, superior long duration capability
- Large-capacity built-in metal lithium battery
- Accurate monitoring of tire pressure stability values all the way
- High precision LCD display
- Large volume alarm sound alert
- A variety of tire pressure units are available
- Long receiving distance with stable signal
- Support tire position interchange
Function:
Real-time monitoring: The tire's pressure and temperature status can be monitored regardless of whether the vehicle is running or at rest. The tire status is under control.
High pressure/low pressure alarm: When the tire pressure is higher or lower than the set value, the system will give an alarm.
Air leak alarm: The system will give an alarm if a foreign object penetrates into the tire an
