"My grandmother is old, her legs, feet and eyes are not good, and she sometimes wrestles when she goes out, so I designed a smart crutch. It uses photosensitive LED, tracking module, battery box, DuPont wire and other materials. When the tracking module senses that there is an obstacle in front of the crutch, the crutch will vibrate to remind the user; When it gets dark, the photosensitive LED will light up automatically. The elderly, the disabled and outdoor adventures can all be used. " Wang Yuqi, a student at Shahe Primary School in Wanzhou District, said.
Lei, a student of Liyuchi Primary School in Jiangbei District, showed her own intelligent and environmentally friendly home system. He said: "Solar panels absorb light energy and then convert it into electrical energy for storage, supplying power for houses, cars and street lamps. The street lamp has a photosensitive sensor, which will automatically turn off after dawn. The LED light on the roof will light up regularly to remind the height of the aircraft building. The thermal sensor in the house will also trigger a buzzer alarm when it encounters high temperature, which can prevent fires. "
Xing Mian, a student of Bachuan Middle School, directly used the shell of the science box of "Wisdom creates everything", and installed power supply, photosensitive sensor, buzzer module and LED lamp on it to design a set of intelligent door system. He said that he often saw children unable to ring the doorbell because of their height, so he thought of turning the doorknob into a doorbell sensor. The judges and teachers all recognized his design and suggested that he apply for a patent.
