Marine Litter Detective

Do you know where marine litter comes from?  A lot of litter generated on land actually ends up in the ocean, but how? WWF-Hong Kong, in cooperation with MakerBay, has designed a tracking device to simulate how litter enters the sea through storm drains and rivers, and is working with students from 11 schools to trace the journey of litter. This helps us understand the source of marine litter in Hong Kong and solve the problem together. If you find this device washed onto the shore, please pick it up and contact WWF (pyeung@wwf.org.hk) for collection. This project is sponsored by the Environment and Conservation Fund and the Environmental Campaign Committee of Hong Kong SAR Government.

Data visualisation

Student Drifters

We have been very impressed with the work of Student Drifters, a research based program and we are learning a lot from them, principally about from their

Software server side

Server

We are using a simple MySQL Server to collect the data via ftp/http request. We are currently using a PHP script to extract the data and prepare it for data visualisation via a Json, or CSV file.

Software on device

Device

On the device we are using the Arduino IDE: https://www.arduino.cc/en/main/software

Electronics

Electonics

The devices are equipped with a 3.3V Arduino Pro Mini

Casing

We are trying to get our electronics as “eco” as possible, so the housing of our electronics is mainly composed of
