Universal TPMS Tyre Pressure Monitoring System with External Screw-on Sensor, Solar Panel + USB Charging and IP67 Waterproof

Universal Tyre Pressure Monitoring System with 4 External Sensors

The MT-S4 is a wire-free tyre pressure monitoring system for cars, SUVs, vans and light trucks. Four external screw-on sensors transmit real-time pressure and temperature to a solar-powered dash display, so drivers read live tyre pressure without opening the door of a workshop. Where a simple warning light is not enough, this tyre pressure monitor shows the exact psi of each wheel and sounds an alarm before a slow leak becomes a roadside problem.

Key Features

• Solar powered display - no wiring, no lighter cable; USB charging is provided for winter or indoor use.
• Four external sensors - screw onto the valve stem in under one minute, no tyre removal required.
• Real-time readings - simultaneous pressure and temperature display for all four wheels, refreshed every 5 seconds.
• Four alarm types - low pressure, high pressure, high temperature and fast leak, with audible and flashing warning.
• IP67 waterproof - sensor and display rated for rain, mud and pressure washing, -30 to 85 Celsius degree.
• Two year sensor battery - replaceable CR1632 cell, so no return-to-factory service.

Technical Specifications

Installation

1. Screw each external sensor onto a valve stem and tighten the lock nut with the supplied spanner.
2. Place the solar display on the dashboard or windshield with the anti-slip pad.
3. Power on and pair each sensor in the ID menu, then set the target pressure and alarm thresholds.
4. Charge by sunlight; if the vehicle sits in shade, top up with the USB cable.

FAQ

Q1: Does this tyre pressure monitoring system need professional installation?
No. The external sensors fit standard valve stems and the display needs no wiring, so any driver can install it in minutes.

Q2: Can it work on a 24V truck?
No. The display is charged by solar and USB, independent of the vehicle voltage, so it suits 12V vehicles.

Q3: Will the sensors fit tubeless and tube-type tyres?
External sensors fit standard valve stems on tubeless tyres. For tube-type wheels we recommend the internal sensor kit version.

Q4: What is the MOQ and lead time?
MOQ is 100 sets, stock orders ship in 7-10 working days and bulk production takes 20-25 days.
