Description: This machine can provide a comfortable growth environment for plants. It can monitor the growth progress of plants, automatically recycle rainwater, maintain balanced watering, fertilize, and give plants enough light. It can also avoid forgetting to water, watering too much, lack of nutrients, and so on. Therefore, it is very smart and convenient, and requires almost no human hands.
The Automatic Plant Growth Monitor uses a transparent offset plate with holes as the shell, so it is very ventilated. The black part is the main control board, including the following sensors: moisture sensor, resistive soil moisture sensor, temperature and humidity sensor, analog ambient light sensor, liquid flow sensor, screen (LCD 12864), normally closed water inlet solenoid valve, IoT module, ultrasonic distance sensor. The two ultrasonic distance sensors are installed on the top and rear of the automatic plant growth monitor, and these ultrasonic distance sensors can measure the distance between the plant and the sensors, so that it can judge the size. When the sun sets, the automatic plant growth monitor can automatically turn on the yellow light to imitate the sunlight. When it rains, the monitor will cover the baffle, and the box next to the machine will catch part of the rainwater, and then let the rainwater flow into the bottom of the flower pot when it is time to pour water, and then use the cotton rope to seep the water into the soil. The nutrient solution behind the flower pot will be injected into the soil through the normally closed water inlet solenoid valve and the liquid flow sensor.
