Intelligent Watering System for Indoor Green Plants
An automatic watering device has been designed to maintain potted plants in an intelligent and reasonable manner,sloving the problems of not being able to water in a timely manner and unable to control the amount of water dur-ing the cultivation process.Using a microcontroller as the internal controller,the device is equipped with environmental pa-rameter detection equipment such as temperature and humidity sensors and liquid level sensors,which can intelligently re-spond to the potential needs of indoor environment and soil.By using PID control algorithm to control the water output of the inlet and outlet pumps,the expected water output is set to SP and the actual water output PV is detected in realtime.By calculating errors and controlling the corresponding relay device based on the control variable U output by the PID con-troller,intelligent control of the automatic watering device is achieved.
