Abstract

This research aims to develop a weather-measuring instrument with sufficiently high observation accuracy at a low cost, even if its durability is not high. The instrument body was constructed using a 3D printer, and inexpensive sensors and microcontrollers were used for the sensor and control unit. For the natural ventilation thermo-hygrometer, the radiation shield was constructed with a 3D printer, and the temperature/humidity and control components were developed cheaply. As a result, the temperature inside the enclosure was easily affected by solar radiation due to the thermal conductivity of the 3D printer filament. For the forced ventilation thermo-hygrometer, a forced ventilation tube was made of a fan and a PVC pipe. As a result, the temperature accuracy became higher, removing the influence of solar radiation sufficiently. The water storage rain gauge was constructed using a load cell sensor and could measure changes in rainfall during rainfall cases. However, its use is currently limited to short-term rainfall events. Therefore, a tipping bucket rain gauge is required to develop for future research.
