This is an internal (in-wheel) tire pressure monitoring system for passenger cars, featuring built-in Bluetooth sensors (Bluetooth 5.1) and a solar-powered display unit. The sensors are installed inside the tires for accurate, theft-proof pressure monitoring, with acceleration-triggered transmission and data updates with every tire revolution. The solar display provides auto-positioning, voice alerts, and 24-hour parking monitoring for complete driving safety.

• Internal Bluetooth sensors (installed inside the tires, Bluetooth 5.1 communication, adaptive mounting angle)
• Solar-powered display unit (real-time display, voice broadcast, gravity sensing, 24-hour parking monitoring)
• Mounting accessories (mounting nuts, balance weights, wrench, user manual)

• Features: Auto-positioning, parking (24-hour) monitoring, voice broadcast, gravity sensing

• Bluetooth 5.1 communication: stable, low-power wireless data transmission
• Quick data updates: data refreshes with every tire revolution for real-time accuracy while driving
• Auto-positioning: sensors automatically identify their installation positions — no manual setup required
• Parking monitoring (24 hours): continuous monitoring even when the vehicle is parked; abnormal pressure or slow leaks trigger an alarm in time
• Voice broadcast: clear voice alerts for abnormal pressure or temperature while driving
• Gravity sensing: the display unit automatically adjusts to the vehicle's state for optimal viewing
• Solar power supply: no charging cable or wiring needed — self-powered and maintenance-free

• Theft-proof design: sensors installed inside the tires are protected from theft and external damage
• High accuracy: 0.05 Bar measurement accuracy captures even minor pressure changes
• Wide temperature range: sensors operate at -40~125℃, display unit at -10~85℃
• Bluetooth 5.1: low power consumption with stable, fast data transmission
• Solar-powered display: energy-saving, no wiring, low maintenance
• 24-hour protection: parking monitoring covers the vehicle even when unattended
• Long service life: 3-year design life reduces replacement costs

• Passenger cars: sedans, SUVs, and MPVs — daily tire pressure monitoring
• Highway driving: real-time monitoring at high speeds for blowout prevention
• Aftermarket upgrade: ideal retrofit for vehicles not originally equipped with TPMS
• Family vehicles: 24-hour all-weather protection for commuting and long trips
