Automatic Plant Waterer

Final Project: Welcome

About

This invention measures the room temperature using a TMP sensor and automatically waters the plant by rotating the servo motor arm at a predetermined interval based on the temperature.

Executive Summary

This automatic plant waterer waters plants at a predetermined interval based on the room temperature. This project was made for my roommate and I as we both are irresponsible at watering our plants frequently but enjoy having them because they look nice. The invention uses a TMP sensor to detect the outside temperature and servo motor to control the arm that lets water flow out. If the room temperature is above 65 degrees fahrenheit, the servo motor will turn to allow water to drip out of the bottle for 10 seconds every four hours. If it is between 50 and 65 degrees, the waterer will water the plants for 10 seconds every 12 hours. If it is less than 50 degrees, the waterer will water the plants for 10 seconds every 36 hours. The idea behind this is that the hotter the room is, the more water the plants will require and thus the more frequently they will be watered. I chose this solution because it only required materials that I already owned, making the budget for this project very low. I did not use outside resources while creating my project. However, after creating it, I looked online and saw that there were many similar projects. Therefore, if I were to redesign this project in the future, I would modify it so that water is pumped up into the basin instead of having an upside-down water basin. Creating this project taught me the importance of thoroughness -- while actually building it there were a lot of moments where I realized I had not thought through exactly what I would need to do, and if I had planned better the process would have been smoother.

Perspective Sketch

My prototype changed a lot since making this perspective sketch, because part of my design rationale changed. When I made the perspective sketch, I still was unsure of how I would get water into the water bath, so I added water bottles and an arm for the servo motor. I made these changes because they simplified my design. I also added a piece of cardboard on the side to hold the servo motor, which I did not draw in the perspective sketch. I did this so that the motor had support and would not fall.
