Among them, the model of the control chip 1 is STC89C52; the model of the temperature and humidity sensor is DHT11;

The control chip 1 processes the information of the temperature and humidity sensor 2, the soil humidity sensor 6 and the photosensitive module 4, drives the motor 3 and the relay 5 to work; when the humidity of the flowerpot 12 corresponding to the soil humidity sensor 6 is lower than the preset value, the control chip connected to it The pin of 1 outputs a low level, and the control chip 1 drives the servo 7 to rotate to the flowerpot 12 where the humidity is lower than the preset value according to the rotation angle set when the pin is low;

The control chip 1 turns on the power supply to the water pump 8 through the control relay 5, and the control relay 5 turns off the power supply to the water pump 8;

The photosensitive module 4 detects the intensity of light, and the resistance value corresponding to the light intensity is preset in the program of the control chip 1. When the light intensity sensed by the photosensitive module 4 is small and the corresponding resistance value is greater than the preset value, a high level is output , when the light intensity sensed by the photosensitive module 4 is relatively large and the corresponding resistance value is less than a preset value, a low level is output;

The temperature and humidity sensor 2 detects the temperature in the air;

Soil moisture sensor 6 detects the humidity in the soil in real time;

The motor 3 is installed on the front two wheels on the car body 10 respectively, and is connected with the output end of the control chip 1 by two wires respectively, when these two output ends all send 10 signals, the car body 10 advances; When both output terminals send a 01 signal, the vehicle body 10 moves backward; when the left output terminal sends a 01 signal and the right output terminal sends a 10 signal, the vehicle body 10 turns left; when the left output terminal sends a 10 signal, and the right output terminal sends a 01 signal , the car body 10 turns right;

The line tracking module 13 includes five pairs of infrared tubes installed side by side. The infrared tubes include an infrared emitting tube and an infrared receiving tube. The infrared emitting tube sends infrared rays, and the black lines on the ground reflect infrared signals to the infrared receiving tube. The tube sends the signal to the control chip 1.

Figure 3 is a flow chart of the robot, and the workflow of the robot is as follows:

The number of flower pots in this embodiment is 3. Put the soil into the flower pots. The program in the control chip 1 sets the position of the middle flower pot as the origin position, and the positions of the flower pots on both sides are positive and negative relative to the origin position. 30 ° position; set a black line on the ground; put the soil moisture sensor 6 into the soil corresponding to each flowerpot 12, preset the time of entering and leaving the room in the control chip 1, and the car body 10 will follow the preset time. Time moves outside the room or in the room along the black lines on the ground by the line tracking module 13. During the outside of the room, when the humidity of the soil of any flowerpot 12 is detected by the soil humidity sensor 6, it is higher than the preset value of the control chip 1. When setting the value, the water outlet 9 is at the origin position; when the soil humidity sensor 6 detects that the humidity of the soil in any flowerpot 12 is lower than the preset value of the control chip 1, the control chip 1 controls the steering gear 7 on the rotating plate to turn The direction of the flowerpot corresponding to the low-humidity soil, the water pump 8 installed on the rotating plate drives the water outlet 9 as the rotating plate rotates from the origin position to the direction of the flowerpot corresponding to the low-humidity soil, the control chip 1 controls the relay 5 to guide Through, the water pump 8 is energized, and the water pump 8 extracts water from the pool through the water outlet 9, and the water outlet 9 sprays water on the soil in the flower pot with low humidity, and the soil humidity sensor 6 continues to monitor the humidity in the soil. When the soil thermometer 6 detects When the humidity of the received soil is higher than the preset value in the control chip 1, the control chip 1 controls the relay 5 to disconnect, the water pump 8 stops pumping water, and the water outlet 9 returns to the original position; Low situation, then first the humidity of the flowerpot that needs water spraying is brought up to preset value, then water outlet 9 is rotated to the origin position, then rotates to other flowerpots with low humidity to spray water to it; photosensitive module 4 detects light When the light intensity is lower than the preset value, when the photosensitive module 4 outputs a high level, the car body 10 does not move; when the light intensity is higher than the preset value, when the photosensitive module 4 outputs a low level, the control chip 1 controls The motor 3 drives the car body 10 to move into the room along the black line, so as to avoid the plants planted in the flower pot 12 from dehydrating too much and withering; when the temperature and humidity sensor 2 detects that the air temperature is higher than the preset value during the period outside the room, The control chip 1 controls the motor 3 to drive the car body 10 to move into the room along the black lines, so as to prevent the plants planted in the flower pots 12 from losing too much water and withering. If any index of light intensity and air temperature exceeds the preset value, the control chip 1 controls the motor 3 to drive the car body to move into the room.

Embodiment 2: the soil is replaced by a sponge, the number of flowerpots 12 is 4, the program setting origin position in the control chip 1 is the midpoint position of the tray, and the first flowerpot is placed 30° to the right from the origin position, The second flowerpot is placed at 60° to the right, the third flowerpot is placed at 30° to the left, and the fourth flowerpot is placed at 60° to the left; other features are the same as in Embodiment 1.
