This thesis describes the work of two students who designed the control system of a stand-alone water well measuring system, named SubDowser. The project was done by order of a proposal from the start-up company SkyDowser. The total thesis group, consisting of three subgroups, was asked to build a working prototype which could measure the water level, conductivity and temperature within a water well. Subsequently, this data needs to get uploaded to a server located in Delft. When designing the control system clear requirements and interfaces were set. From these demands numerous considerations were taking into account resulting into using two LPC1768 microcontrollers to control the whole system. One stationed underground acting as slave and one stationed above ground acting as master. These two microcontrollers communicate with each other by two differential drivers using the RS-485 standard. The development and implementation of the written programs were done on the mbed IDE, which was provided by the used developers board. From the result can be stated that a decent working prototype has been developed in fulfilment of the requirements. However, there is still room for improvement.
