Discussion/Conclusions

After a year of hard work we were able to develop a system that accurately monitors a plant's soil moisture content and waters the plant when necessary. Though this was a seemingly simple and straightforward system, it was not without its challenges and pitfalls. We learned a great deal about planning, research, sourcing parts, plant care, software development, soil, hardware design, teamwork, presentation, professionalism, and design implementation.

Our working prototype is a start, but there is more work to be done. There are several future improvements we would like to make as time and budget allow. The first of which would be to make the WASP wireless so that multiple units can be controlled from a single Raspberry Pi. We would also like to improve the overall aesthetic of the watering unit so that it is functional, yet discrete. Finally, we have considered implementing additional sensors for pH, temperature, salinity, and N-P-K levels for a complete soil health profile.
