Our inspiration came from a need to come up with a solution to combat climate change due to global warming.
What it does
We've created a soil moisture sensor that can be place within the soil to detect levels of moisture. It has an LED indicator that would allow users to know when to water their plants or crops. If the soil is too dry, the LED glows red, if it is time to water, the LED glows orange. Soil that has enough water would be indicated by a green LED. Too much water would glow blue.
How we built it
We used an Arduino M0 pro micro controller board with a moisture sensor and a single RGB LED. Coded in the Arduino IDE, using C-plusplus we have the sensor return an output to indicate the level of moisture from 1-750. We've set the LED to glow certain colors based on a range of moisture levels.
Challenges we ran into
Implementing WiFi connectivity, due to limited time of this hackathon we were unable to implement an automatic alert system to send an SMS text to users if their soil was too dry or too moist.
Accomplishments that we're proud of
We've created something that actually works and is feasible to bring to market that does help with water conservation.
What we learned
We learned that an idea can be effective even though it may seem simple. Utilizing what we have and coming up with a viable product for consumers has taught us how to work together in a team.
What's next for Soil Moisture Sensor
Connecting it to WiFi and having multiple sensors over a large plot of land or acre and giving the user an idea of where there is too much moisture or where a certain patch of land needs watering.
