Lego Weather Station - IoT concepts

Former Member

This Lego Weather Station is an exercise in IoT concepts using an Arduino (Cactus Micro Rev2) which has a built-in ESP8266 WiFi module. It then sends the sensor data using MQTT to a Mosca MQTT broker. A Node-RED client subscribes to the data feed, stores it into a MongoDB and then visualizes it with a Google Chart. The blog article is more about the journey than just the destination image . This is one of many cool projects in the Internet of Lego city, which examines all sorts of interesting embedded, NodeJS and IoT concepts using Lego.  Full Story: Weather Station – DHT11, MQTT, Node-RED, Google Chart, Oh My! | Internet of Lego

    Cool, thanks for the feedback. I'm always experimenting with IoT tech and related hardware/software. Why not have some fun with LEGO at the same time?! If you have any ideas, I'm all ears. My next project is going to be a Train station that switches the track based on the Transport for London API and also publish the next trains on an OLED screen. Data is already being sent via MQTT and or PubNub via my NodeJS/Node-RED apps, just need to build the interface.
