Connecting Node-RED to Azure IoT Central
Today I want to show how simple it is to connect a temperature/humidity sensor to Azure IoT Central using a Raspberry Pi and Node-RED. As many of you know, Raspberry Pi is a small, single-board computer. Its low cost, low power nature makes it a natural fit for IoT projects. Node-RED is a flow-based, drag and drop programming tool designed for IoT. It enables the creation of robust automation flows in a web browser, simplifying IoT project development. For my example, I’m using a Raspberry Pi 3 Model B and a simple DHT22 temperature and humidity sensor, but it should work with other models of the Pi. If you have a different kind of sensor, you should be able to adapt the guide below to use it, provided you can connect Node-RED to your sensor.
