Abstract
Agricultural greenhouse is the most common form in agricultural production. Because it adopts a variety of control technologies, it can realize the accurate cultivation of various crops and vegetables, better meet people's consumption needs, and adopt greenhouse technology for cultivation. In this context, in order to meet the development requirements of intelligent agriculture, an agricultural greenhouse monitoring system is designed, which can better meet the needs of agricultural production and water conservation.
The system adopts STM32F103 single chip microcomputer as the main controller, and is equipped with sgp30 carbon dioxide sensor, gy-302 light sensor, DHT11 temperature and humidity sensor, oled12864 LCD and isd1820 voice module. In terms of function, it realizes the functions of temperature and humidity detection, carbon dioxide detection and light detection. When the humidity exceeds 40, the voice module will give an alarm, and when the light exceeds 100, the buzzer will give an alarm, And display through OLED liquid crystal.
In this design, the hardware circuit and software program of the system are designed, and the system design function is verified by making physical objects. Through function debugging, the overall design meets the actual design requirements, and can achieve the functions of carbon dioxide detection, temperature and humidity detection and other objectives. The overall system runs stably and has perfect functions, which can improve agricultural production efficiency, and has important commercial application value.
