Review on Efficient Self-Watering For Your Garden With WayinTop'S Automatic Irrigation DIY Kit by Adam Jacobs

First thing to know is that this set of items does not include the microcontroller or instructions (may be available if you contact the company) to build the auto-watering system. This only includes the pumps, sensors, relay board, and tubing. Any Arduino or other microcontroller is sold separately and will need to be programmed to work with this hardware.With that out of the way, if you are in the market for these components, this kit is a great deal and works great! These are the same pumps and sensors you'll find being sold separately at places like Adafruit or Digikey. The relay board isn't really strictly needed for most projects, but feels solid and works great. (I'm going to end up using this for another project that requires controlling higher voltage than the 3-5v motors in this kit).Really, the only negatives with this kit are in the fact that it doesn't include all the components as a stand-alone pack to build the auto-watering system. As long as you know that going into it, this is a great deal!
