Meituan helmet has built-in sensors and smart chips, which can sense whether the helmet is worn on the head. When the helmet is worn correctly, the sensor will sense the contact of the head, thus confirming the wearing state.
Cyclists need to use App scan code to bind one by one in order to turn on the smart helmet detection function and collision detection function, thus solving the problem of "wearing or not wearing" the helmet in reality. The rider App can display real-time wearing status and record helmet wearing data.
