How to Make a Smart Buoy for Water Quality #CitizenScience #Arduino #DIY #science #water #STEM
High school students are stepping up the game nowadays doing tech projects that target real life problems. According to Hackaday, Bergen County Academies in Hackensack, New Jersey is doing some innovative work with its own Mechatronics Research Lab. Students there decided to explore the health of the Hackensack River by creating Intellibuoy, a system that uses PVC pipes, Arduinos and sensors to capture data above and underwater.
Specifically, two Arduino Unos power weather monitoring near the top of the unit, including wind direction, wind speed and rainfall. The Arduinos also power some sensors below, including temperature, oxygen saturation, turbidity and pH. Apparently the team has also created another version of this unit using an Arduino Mega, so it looks like they are already working on simplicity. You can check out the documentation of this project on Instructables, and hopefully there will be an update once a field test is performed in the river. What will boats think of this floating LED beacon, and what does the Hackensack River look like in numbers?
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
