Arduino Automatic Smart Plant Watering Kit 2.1
Our Growcube Arduino Automatic Smart Plant Watering Kit is based on Arduino Lenardo which has integrated into the mainboard. We add a RTC to set timing watering and a 0.96 inch OLED 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. Compared with the resistance moisture sensor, the soil moisture sensor is made of a corrosion resistant material, which will provide a long service life. The Smart Watering Kit allows providing all your own smart plant monitoring system with ease of use and unlimited options!
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.
This board is different from the last version, it only can be used for the smart watering system.
