1. はじめに
The wiiyii M4 Heads-Up Display (HUD) is an OBD2 system speedometer designed to project essential driving data onto your vehicle's windshield. This technology aims to enhance driving safety by allowing drivers to view information such as vehicle speed, water temperature, and voltage without diverting their gaze from the road.
The M4 HUD features a high-brightness LED display with an integrated light-sensing sensor for automatic brightness adjustment, ensuring clear visibility in various lighting conditions. It also includes multiple alarm functions for overspeed, water temperature, voltage, and fatigue driving.
