The final outcome is a device that can silently monitor the plant and let the user know when they need to add water. During normal operation, while the plant is properly watered, the device sees the resistance is below its threshold so it does not send a text message, it only lights a soft green light. It is constantly checking if the resistance level has changed, but each day it checks to see if it needs to send a text message to alert the user. If the resistance level changes, the green light shuts off and a red light appears. The user also gets a text message saying “Water your plant soon!” The next steps for this product would be to build a housing that can hide the electronics, and develop a power source. In this case, a solar cell could be an easy power source since the plant relies on sun and if the code was tweaked to only check once per day to save power.
Is this a good/useful/informative piece of content to include in the project? Have your say!
