If often it happens that you have to travel for 2-3 days. And during that period you cannot water your plants at home, our idea and teachings make you will be able to travel without worrying about them.
Please make sure to work in safe environment (it is electronic!).
Our Automatic Smart Plant Watering Kit for Arduino is based on the KEYESTUDIO PLUS Control Board and Sensor Shield. We add a DS3231 clock module to set timing watering and a I2C LCD display to show the time and the soil moisture status. The kit includes a pump, capacitive soil moisture sensors, water switch to redirect the water to up to 4 plants and pipes for the water to go through.
When you power the board after uploading the Arduino program we attached in the wiki, the board using the 4 soil moisture sensors to determine the soil level in the plant. The board will send the command to the switch to open a specific channel for a specific plant that needs water currently (up to 4 plants at once). Afterward, the board will send the command to turn on the pump and suck water into the switch, the switch will separate the stream and will give just enough water for your plants. Then it will close the pump and the switch and continue to check when does your plant needs water.
