15:30 - 18:00	Ying Wa College	Smart Glass Building	The ‘Smart Glass Building’ uses smart glass instead of curtains to reduce plastic waste and maintenance costs from traditional curtains. It can adjust its transparency to block or allow sunlight depending on the temperature. The key to intelligent dimming glass is to determine the colour-changing time. Photoresistors are too sensitive and can react incorrectly at low luminosity, while detection by solar panels can improve accuracy. The current generated by the solar panel is proportional to the luminosity. When the sunlight hits the solar panel, the current sensor will detect the current value and the micro:bit will check whether it is higher than the upper limit. If the value exceeds, it will send a signal to another micro:bit to control the smart glass to become translucent, then reduce the light entering the room and the temperature rise. It is expected to achieve the effect of energy saving.

They incorporate technology into artificial bird nests, allowing relocating birds to receive better protection and monitoring with minimal interference. The students first collected about the habits, locations, breeding periods and survival needs of this species, then conceived a suitable bird’s nest design based on their problems. In addition to considering the materials and size of the bird’s nest, the design also needs to consider elements such as the location of placement, the research data to be collected and necessary protection functions. At the same time, to prevent hackers from intercepting data for illegal purposes, the plan also needs to introduce network security concepts and set up defences from various aspects such as data transmission and access.
12:15 - 14:15	Caritas Wu Cheng-chung Secondary School	Automatic Home System	This school has designed an automatic home system, hoping to improve the difficulties encountered by subdivided households. The system uses air detection equipment to ventilate air at an appropriate time. When the air quality is detected to drop, the automatic air dredging equipment is activated. The air detection instrument can quantitatively detect the concentration of pollutants through optical characteristics such as reflection or diffraction. After that, it will output the measurement results through the serial port. The principle uses the channel sensor of the LED and the lamp to judge the light transmittance of the particles in the air and know the air quality. When the air detection instrument detects that the air quality has declined, Arduino will judge the air quality, make an analysis, and control the fan blades based on the specified data to dredge the air in the room and reduce the impact on the subdivision households. In addition, to reduce the electricity consumption of subdivided flats, the system uses solar panels as the main energy source of the system. The subdivided flats can install solar panels on the roof. This device can reduce power consumption in subdivided households and reduce environmental damage.
