It mainly includes main control module, LCD display module, key control module, humidity detection module, water pump module and WI-FI module, which makes the whole system join the Internet of Things to realize full automation. The system can judge the status of the growing environment of green plants through the detection of soil temperature and humidity, that is, water shortage or dehumidification. And the user can manually adjust the threshold range of soil moisture, LCD display screen displays the current soil temperature and humidity information. When the soil moisture is lower than the set threshold, the pump is started to pump water, and when the threshold after watering is within the set humidity range, the watering is stopped. The addition of the WI-FI module tries to connect the whole system with the Internet of Things, which is convenient for users to monitor and operate on the mobile phone.展开更多
