When we take the subway or bus, many passengers always swarm in it when it has not parked yet, which is very unsafe. In this regard, we have designed a color-changing warning light.
It is connected to the arrival information of vehicles. Built-in piezoelectric power generator can aggregate every small force by pedaling of a great flow of people.
When passengers step on the warning light line, the pressure sensor in the light line will receive the signal and the red light will be on with a sound. The simple and direct way can better warn people to avoid security risks and protect the safety of passengers.
