Pollution Sensors...
Overview
The following is a lesson to help my students develop a plan or ways to find pollution in the ocean to help the environment.
Design Challenge Title: Ocean Health Monitor
Author(s): Bill Traphagen
| Background and Question/Challenge: Ocean Health Monitor I micro:bitMicrobit Increase scientific knowledge,develop research capacity and transfer marine technology, taking into account the Intergovernmental Oceanographic Commission Criteria and Guidelines on the Transfer of Marine Technology, in order to improve ocean health and to enhance the contribution of marine biodiversity to the development of developing countries, in particular small island developing states and least-developed countries. Make working prototypes of wireless sensors which could be used to monitor the environment at sea, including waves and weather and learn about how real-world sensors are connected through gateways to the internet. | |
| SDG Goal: Ensure availability and sustainable management of water and sanitation for all. | Why is this challenge relevant to students? One in three people live without sanitation. This is causing unnecessary disease and death. Although huge strides have been made with access to clean drinking water, lack of sanitation is undermining these advances. If we provide affordable equipment and education in hygiene practices, we can stop this senseless suffering and loss of life. |
Constraints/Criteria: Design and create a floating sensor node using a micro:bitThe beacon must transmit sensor data to a gateway micro:bit every 10 secondsThe beacon must also transmit its unique ID number (there will be lots of nodes!)The gateway micro:bit must be able to show the data on its LED screen
