Nowadays, everyone has a lot of things to do, so their life and work are under great pressure. They need to relax in order to provide better work efficiency. In the office only green plants can relieve their stress. When they see the green plants, they will feel relax and comfortable. But sometimes maybe they will too busy to water the flower, so in order to avoid this situation, we have developed an automatic flower watering kit.
Function
Insert four soil moisture sensors into four plant pots, and put four water pump pipes in the pots. You can see that the LCD1602 display show soil moisture value. If soil is humid enough, the backlight of the LCD1602 display will be turned off after 10 seconds, which can save power. If soil lacks water, the backlight will light up, and water pumps will pump water to pots. After 3 seconds, the relay will be turned off, the water pump will stop pumping, and wait for 5 seconds, then the soil humidity sensor will continue to detect.
