Our Arduino Automatic Smart Plant Watering Kit new version is coming! The smart watering kit is based on Arduino Lenardo which has integrated into the main board. 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 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.
Eliminates the need for messy jumpers and breadboards, connect all sensors and modules with ease!
Integrated Arduino UNO into the main board, program it easily.
Power the board with single 12V power supply directly.
4 interfaces for sensors, one interface for water switch and one interface for motor or pump.
The kit works ok. The pumps relay and moisture sensors all function as advertised.
My kit came with the Crowduino v2.0. I like this board better than the generic Arduino one.
The smart pump shield v1.0 schematics are no where to be found. I've reverse engineered most of it but still have questions that the schematics and layout would/could answer.
The copper plated moisture sensors begin to corrode after some time in moist soil. I'd like to be able to power them off when not sensing. That should be straight forward enough to do. It looks like the power to the sensors has it's own trace, but without disassembling the board I can't tell.. (Posted on 8/26/2018)
