When you power the board after uploading the Arduino program we attached in the wiki, the board using the 4 soil moisture sensors to dentermine the soil level in the plant.The board will send command to the switch to open specific channel for specific plant that needs water currently (up to 4 plants at once).
Afterwards, the board will send 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. It's possible to make it even smarter with light sensor so for example the plant will not be watered at night or with rain sensor so if it's raining, don't water the plant as well. The smart watering kit is based on Crowduino Smart pump shield which is included as well with the kit.
The Smart Pump Shield is a brand new one-of-a-kind shield that allows to build projects with ease and elimate the need of jumpers, breadboards, mess and complexity. The smart pump shield, orignally developed for smart watering kit allows to connect multiple sensors including humidity sensor, light sensor, rain sensor and soil moiusture sensors. it provides 5 relays that can be controlled seperately by pins or by integrating the interfaces. 4 relays can control 4 channels water switch directly and the 5th relay can control a pump, all by crowduino interfaces for ease of use and less complexity. The board also provides 12v input that split between the board and the arduino, providing the arduino 5v input, that eliminates the need of another seperated power adapters.
The shield can be used for versious projects including but not limited to smart watering system, smart home, vending and drinking machine, cocktail mixer and so on.
Features
Eliminates the need for messy jumpers and breadboards, connect all sensors and modules with ease!
Integrated Arduino UNO into the mainboard, program it easily.
Power the board with a single 12V power supply directly.
4 interfaces for sensors, one interface for water switch and one interface for motor or pump.
