Story

In this project, we are using an Ultrasonic sensor to monitor a changing water level, in this case a fishbowl. This is useful as a this is a constant monitoring system for any liquid that undergoes constant changes, which has many applications including water levels in nuclear reactors. The Internet of Things allows this solution to come alive as if the system gets below at or below a critical level a LED light will illuminate. This can be helpful for fish owners because it can be difficult at times to remember to check the water levels which is important to a healthy environment for the fish. our project also has an input so that a fish owner can see exactly when they have fed their fish throughout the day. This is monitored on a graph and lets you know the data was recorded since it will illuminate the onboard led for a few seconds. The solution is unique as this solution is far less expensive others that use the same technology which start around $300.
