dc.description.abstractThis master’s thesis presents the first stages of a project which aims to build an accurate and efficient capacitive bee-counter, a device that can count the number of bees entering or exiting a hive. This device has an essential role in protecting this species from hazardous pesticides, but current systems in the market are not convenient due to their lack of accuracy or their unsuitable functionality. First, capacitive sensor development is presented. Taking into account the design constraints of this device and its environment, a capacitive sensor is developed to ensure high precision into the measurements. The study follows testing out the devised capacitor with different Capacitive-to-Digital converters. From this experimentation, the sensor performance is evaluated and a suitable converter is chosen. Employing these elements, a prototype is built to gather data in a real environment. Then, data samplings are performed using the prototype in an apiary. Inspecting the signals collected, conclusions regarding the measurement technique are achieved and series of bees’ behaviours are detected. After this first experimentation, the prototype is upgraded so it can be employed in any hive, improving its design and attaining new information during following testing sessions. Finally, the different signal processing techniques trialled out are described. Their objective was to perform or aid in the bee-counting process. The results of their application are displayed, explaining its dismissal or possible utilization. Later, a suitable methodology for the end product is proposed. Along with its definition, the best results obtained by its implementation employing MATLAB® are presented and pointers for future improvements in its performance are described
