The invention discloses an automatic flower-protection flower pot device comprising a flower pot body used for accommodating a plant, a water inlet pipe arranged on the bottom of the flower pot body, an electric valve arranged on the water inlet pipe, and a control circuit board arranged on the flower pot body. The flower pot body can be placed on an office desk or a windowsill, and is used for beautify the environment. The control circuit board comprises a data transceiver, a power supply circuit, a data storage chip, a communication interface circuit and an electric valve module. A temperature-humidity sensor, a water amount detection circuit, a flow rate detector and a button setting circuit are connected to the input end of the data transceiver. The electric valve module comprises an optocoupler isolation circuit, an electric valve driving circuit, an electric valve opening/closing device and a current detection circuit. The output end of the current detection circuit is connected to the input end of the data transceiver. The device provided by the invention has the advantages of innovative design and simple structure. With the device, the electric valve can be adjusted according to real-time pot soil temperature and humidity conditions, and water can be supplemented. The device has high practicality.
