![]() ![]() The sensor I’m using in this project is a BME280 made by Bosch which measures 2.5mm square and measures temperature, air pressure and humidity. The Raspberry Pi platform is well supported with sensors allowing for inexpensive development of IoT applications. With a little creativeness this could easily be extended to record other environmental information such as windspeed, rainfall or even air quality. The Raspberry Pi has a good range of hardware extensions (such as GPS units, weather sensors, cameras) and software libraries making it easy to prototype a wide variety of data collection applications.Ī Raspberry Pi can be easily set up as a weather recording station by adding sensors for temperature, humidity, and air pressure. I’m using the Raspberry Pi platform for this blog post series as they are particularly well suited for embedded IoT projects. Having this data written back into a feature service allows for historical analysis to look for changes and patterns over time, but the data can also be used in a control room dashboard where more urgent actions may be required. River monitoring for real-time warnings of flooding events.Environmental monitoring for climate change analysis.There are lots of potential use-cases for this type of sensor data recording and logging such as: This workflow could also be extended to add more weather stations and host their data in the same feature service to build a live weather map. ![]() ![]() Hosting the data in a feature service allows for automatic uploads of weather data, and allows for further analysis of the data over a longer period of time. The libraries used in this article are available on request by emailing this blog, I’ll share how to use the Java Maps SDK to build a simple app that can display and then log weather data gathered from a Raspberry Pi to a feature service. The first blog of the series walked through how to create an inexpensive GPS logger using the Java Maps SDK with a Raspberry Pi. This blog is the second in a series of articles which aims to demonstrate how the beta release of the ArcGIS Maps SDK for Java (with ARM Linux support) can be used for IoT data recording apps. ![]()
