![]() ![]() Our Node-RED environment is ready to get started, but before, we have to create an Azure IoT Central Application and a template for the device data. Go to settings, on the top-right menu, palette, install and search for node-red-node-pi-sense-hat and node-red-contrib-azure-iot-central ![]() Install the Sense HAT node and the Connector for IoT Central, as for any node. In my case I’m connected using VNC to Raspberry and I can browse on 127.0.0.1:1888. If you haven’t done before you can update your Node-RED installation and then you can launch node-RED, as usual, from the browser. If you have never used it, you can find a getting started at the official Raspberry Pi web site. We will use Sense HAT to get temperature, humidity, pression and in a future post the LED matrix. The Sense HAT is an add-on board for Raspberry Pi comprising of a 8×8 RGB LED matrix, a five-button joystick and the following sensors: Gyroscope, Accelerometer, Magnetometer, Temperature, Barometric pressure and Humidity. In a previous post I gave an introduction to the Node-RED connector for IoT Central and because I have been asked to provide more examples with a real device, I have decided to use a Raspberry PI (in my case Pi 2 Model B) with Sense HAT, that allows your Raspberry Pi to sense the world around it. ![]()
