Recently, hardware technology has made feasible a multitude of different types of sensors, and even more impressively the addition of computation power to everyday objects. This new Internet of Things allows us to connect in ways we never before thought possible; importantly, we can now look at soil on farms in more detail than ever before. By combining wireless sensor technology and cloud computing, farmers can unlock data about their fields that will help them produce greater yields and use less water - all from the convenience of their smartphones.
In this talk, we present a data gathering and processing system which utilizes off-the-shelf hardware, and we will discuss the benefits and drawbacks of using retail parts to build a modern IoT system. Specifically, constraints around the sensors will be analyzed, and a novel duty cycling algorithm will be presented for the energy management of the sensors.
