Design and Development of a Low-Cost and Portable Meteorological System: MeteoBlue

Systems controlled through measuring physical environmental parameters, such as temperature, humidity and atmospheric pressure, are very important for the automatization of industrial processes, where advances in electronics have played a key role. This paper presents the design and development of a low-cost and efficient tool based on an SHT11 sensor to measure the temperature and humidity of the environment. The system also proposes a wireless connectivity using Bluetooth communication standard, providing a reliable, portable and low-cost tool for an industry where an environmental control is necessary to carry out critical processes.
