Tire pressure monitoring system TPMS+Solar, external sensors

Description

The Vehemo Solar Tire INT4 PM external-sensor tire pressure and temperature monitoring system (TPMS) installs in the car by yourself and shows readings from all 4 wheels simultaneously online. The head unit is powered from the cigarette lighter or a solar panel, and the sensors have an anti-theft system. As soon as a tire's pressure rises or drops by 25% from the standard value, the system alerts the driver with a sound signal. The external sensors require no special installation at a service station.
