OpenIoTwx: A Low-Cost, Modular Platform for Real-Time Environmental Monitoring

Recorded Talk

Real-time and scalable environmental data is critical for weather monitoring, scientific research, and community decision-making, especially in cities affected by extreme heat and other weather hazards. Local microclimate measurements also complement remote sensing data by providing detailed, ground-level conditions in real-time. However, many commercial weather stations are expensive, difficult to customize, or require technical skills to assemble and operate. OpenIoTwx addresses these challenges through a low-cost, modular, and community-focused environmental monitoring platform. The system collects sensor measurements and transmits them in real time through an Internet of Things architecture. Its modular design allows users to add or replace sensors based on local needs without rebuilding the entire station. During this project, we improved the user experience for setting up new IoT devices by developing a simple web-based flashing and configuration wizard. This reduces the number of technical steps needed to prepare, configure, and connect a device. We also added an integrated 3D-printed globe thermometer for estimating Mean Radiant Temperature, which represents the combined radiative effects of the sun, sky, buildings, and surrounding surfaces on human thermal exposure. In addition, we expanded the platform to support a broader range of third-party environmental sensors, making it easier to add new measurement capabilities for research and community needs. These improvements make OpenIoTwx easier to build, configure, expand, and maintain. The platform can support researchers, educators, and communities that need affordable and accessible environmental data without requiring specialized engineering experience. It can also help communities better understand local heat exposure and other environmental conditions.
