Have you thought about trying out Azure IoT Hub, but don’t have an IoT device? Try the Raspberry Pi Online Simulator. This is what it sounds like, a simulated Raspberry Pi device running a small NodeJS program that sends data to your IoT hub. It sends simulated temperature data using a mock BME280 temperature sensor. All you do is plug in the connection string to your IoT hub and hit ‘Run’. Its even got a little led that blinks when sending data and receiving the callback. Send data with this, and you can view it in near real time using the Device Explorer for IoT Hub Devices. Happy coding!
