1.1 Project Background
In recent years, the incidence of myopia among children and adolescents in our country has been increasing, and there are always many children who wear glasses at a young age in life. Parents have no restrictions on children's eye time, the impact of electronic products on children's eyes, writing posture, some children hold the pen too low when writing, so that the whole person lies on the table, etc. are important factors that cause children's myopia. Nowadays, many children have developed pseudomyopia, and some children even wear glasses early. Parents are very anxious about this and don't know what to do. The currently designed monitoring system for teenagers can detect the correct sitting posture, real-time detection and display of ambient temperature, humidity, and light intensity, and can automatically adjust the brightness of the light according to the ambient light, turn on the fan when the temperature is too high, turn on the humidifier when the humidity is lower than the threshold, etc. , when there is no one, it will automatically turn off the lights to save power resources.
1.2 Design Requirements
