The characteristic value includes a temperature value of rain water, a refractive index or a pH value, and the like. The control signal may be a signal that controls the motor 4 to start and/or control the motor 4 to turn off. The motor 4 performs a corresponding operation after receiving the control signal. For example, when the motor 4 receives the start control signal, the motor 4 performs a start-up operation, that is, starts working to open the telescopic bracket 3. The telescopic bracket 3 is connected to the motor 4, and the telescopic bracket 3 is controlled to switch between an open state and a collapsed state by the motor 4. The canopy 5 is fixed to the telescopic bracket 3 on. When the telescopic stand 3 is opened, the canopy 4 is opened. When the telescopic support 3 is gathered, the canopy 5 is gathered. The canopy 5 is used to block rain. Normally, when the rainwater monitor 2 detects that the rainwater is acid rain, a control signal for starting the motor 4 is sent to cause the motor 4 to work to open the telescopic bracket 3, thereby opening the canopy 5 to avoid acid rain and rain canopy 5 The soil and plants are in contact with each other to achieve the effect of protecting plants and soil.
