The Internet of Things (IoT) enables various applications by providing means to capture environmental effects and possibly control some part of the environment. This is also true for different Smart Farming applications and as a result various systems are available. However, when designing a measurement campaign for a certain task, it becomes obvious that the current products lack flexibility to build the best solution using a single system. This concerns available communication options but also the option to add further sensors for specific tasks. In this paper, we present a modular platform for IoT nodes that can be configured as needed for different applications. We first present our concept and then highlight the ability to use different communication options, power options and the ability to integrate further sensors via adaptation modules. In addition, we show two example use cases that, based on the state of the art, would require multiple parallel systems.
