WeatherChimes: An Open IoT Weather Station and Data Sonification System

Area of Science:

• Environmental Science
• Computer Science
• Education Technology

Background:

• Urban populations exhibit significant disconnection from natural environments, relying on remote satellite data for environmental understanding.
• Existing in-situ environmental sensor systems are often costly, proprietary, and lack flexible data access.
• Accessible, location-specific in-situ data is crucial for validating environmental and weather measurements.

Purpose of the Study:

• To introduce WeatherChimes, an open-source, low-cost hardware and software suite for accessible in-situ environmental sensing.
• To enable near real-time access to diverse environmental data (light, temperature, humidity, soil moisture) via WiFi.
• To explore innovative data interaction through sonification and animation for scientific, educational, and artistic applications.

Main Methods:

• Development of an open-source, Arduino-programmable hardware and software suite named WeatherChimes.
• Integration of environmental sensors (light, temperature, humidity, soil moisture) with WiFi connectivity.
• Creation of Internet of Things (IoT) compatible data formats for online access and analysis.
• Implementation of data sonification and animation applications for data interpretation.
• Testing and validation of sensor and data logging performance in laboratory and field settings.

Main Results:

• WeatherChimes provides near real-time access to in-situ environmental sensor data.
• The system successfully transforms environmental data into auditory signals (sonification) and visual animations.
• Lab and field tests confirmed the reliability and performance of the WeatherChimes system.
• The system was successfully applied in an undergraduate classroom and a STEM education workshop.

Conclusions:

• WeatherChimes offers a low-cost, open-source solution for accessible in-situ environmental data collection.
• The platform facilitates novel ways to interact with and understand environmental data, particularly through sonification.
• WeatherChimes has proven effective in educational settings for teaching environmental science and interrelationships.
• The Internet of Things (IoT) integration opens new possibilities for remote collaboration and data-driven environmental engagement.
