Detecting spikes with streaming analytics

Stream Analytics is a tool that connects IoT Hub to other resources within Azure using a SQL interface. Stream Analytics moves data from IoT Hub to Cosmos DB, storage blobs, serverless functions, or a number of other scalable options. Streaming analytics has a few functions built-in, and you can create more functions yourself using JavaScript; anomaly detection is one of those functions. In this example, we are going to use Raspberry Pi to stream gyroscope and acceleration data to IoT Hub. Then we'll connect streaming analytics and, using its SQL interface, we will output only the anomalous results.
