Learn about how to build IoT solutions for digital agriculture with this 4-part series, part of our IoT for Beginners live streams.
In this episode, Jim looks at migrating from an MQTT broker to a free tier of Azure IoT Hub, making the device more secure and the solution more reliable and scalable. He migrates his Python code running on a Raspberry Pi from using MQTT to using the Azure IoT Device Python package, to send telemetry with soil moisture data, and respond to direct methods to control the relay.

At Microsoft we have built IoT For Beginners, a free, open source, 24-lesson curriculum to teach you all about the Internet of Things. In this series we work through the second project in the curriculum all about digital agriculture, building on the lessons from the previous series.
