We were inspired by victims of Hurricane Harvey with places such as Puerto Rico, The Bahamas, and Texas in mind. Being able to monitor water temperatures, water level, and provide a mesh network for offline communication/alerts and data analysis is important to assist with disaster recovery as well as monitoring daily environmental factors as well.

What it does

Poseidon's Tridents utilizes a rasberry pi, arduinos, and an ultrasonic sensor to function as a water level sensor, temperature/humidity sensor, and mesh network to provide an internet connection at all times. It then uses serial connection to send the data back to a web site on our data page where it is presented to the user in an easy to read format.

How we built it

We cut pvc pipe and drilled holes to allow the water to easily engulf the pipe. We soldered and put together all the wiring for the arduinos and temperature/humidity sensor. Then we utilized various programming languages to get these devices working and collect the data from them on top of building a website to advertise our project and allow users to view the data.

Challenges we ran into

The temperature/humidity sensor is meant for use in soil. Although this device is made to detect moisture, ironically, it is not waterproof nor quite water resistant. Figuring out the proper wiring for the humidity sensor.

Accomplishments that we're proud of

The two main devices built are both i2c devices, which mainly use sda(serial data) and sck(serial clock) i2c is great for IOT scalability as it allows for an array of multiple slave devices on two sda/sck lines coming from a master device, it can also have multiple masters.

What we learned

If planned well and with good teammates a lot can be done in a short period of time. Especially when we are all heavily involved in learning more and working on innovative tools that could possibly make a difference.

What's next for Poseidon's Tridents

Our current project is a small scale design for demonstration purposes. However, if this were to be applied we would have a water proof casing on the top to protect the hardware, many more devices/sensors, longer pipe, optional solar power, and better material. Another upgrade that could be implemented would be a harmful substance sensor, oxygen sensor, and pH sensor. This would allow us to more accurately pinpoint which aquatic areas are struggling and could lead to quicker prevention of deadzones which along with data collection on air pollution are other possible avenues for utilizing this technology.
