Abstract:The urban heat island effect is responsible for higher temperatures in urban areas than in rural areas nearby. With most of the worlds population living in urban areas the high temperatures in these areas are a concern for public health. The municipality of Enschede is concerned of this issue and therefore interested in the magnitude of the urban heat island in Enschede. At the end of last year, the concept of monitoring the urban heat island effect with autonomous sensor nodes was proven to be effective. The goal of this project was to improve the design of the sensor node, so it would be able to give a better image of the urban heat island effect of Enschede. To achieve this goal the phenomenon of the urban heat island and its drivers were researched and with the help of the stakeholders, requirements were setup. A system to meet these requirements was designed using an adapted version of the cyclic design model. Three generations of prototypes were building to evaluate the functionality and accuracy of the design. The results from these prototypes were analysed using data from one of the weather stations of the faculty ITC and used to improve the next prototype. This resulted in a sensor node which measures air temperature, humidity and wind speed with an accuracy relevant for gaining information about the magnitude of the urban heat island effect in Enschede and which can withstand the climatological conditions in Enschede. This node is autonomous as it generates its own power and sends data wirelessly over the LoRaWAN network. This gives a huge freedom of placement as it does not need any infrastructural changes before it can be placed. Next to this, the sensor node is relatively cheap and easy to manufacture. Allowing for a flexible system which can be adapted and expanded with relative ease.
