Teaching telecommunications theory for Engineering Technologies Information students can be viewed as an interesting challenge. This is mainly due to Telecommunications theory which integrates knowledge about two basic sciences: physics and mathematics. The proposal explained in this paper focused on obtaining and deeply understanding the physical concepts related to the theory of telecommunications, rather than memorizing equations, which most of the time would not make sense for students. Engineering students' work focusing on learning the physical and mathematical concepts, was able to design and develop academic tools with two important characteristics for Universities with low budget: easy to use and inexpensive. Therefore, the teaching-learning process is more efficient being adjusted to their endemic circumstances about understanding, knowledge application and few economic resources. Moreover those students were facing less problems understanding and handling the mathematical equations related to the telecommunications theory. Following the proposed procedure, students have designed and built academic tools, such as videos, crosswords, C# applications, graphing on worksheets, and so on. To monitor progress weekly, evaluation was conducted using questionnaires without equations, which were evaluated by the students themselves. Electronic and pedagogical tools were combined to design specific audiovisual aids to facilitate and assure that students were obtaining and retaining those physical and mathematical concepts before starting the equations handling. A comparison was done about groups working under two scenarios: the one described above and the other called in this report "traditional". A drastic difference about student's grades between two groups was observed.

A low cost web solarimetric station tool was developed using an educational solar panel and Arduino microcontroller. Data are shown at Web platform, doing the accessible anywhere anytime, data are also shown at real time. The level of confidence is high due to the proposal was calibrated with specialized equipment to monitoring Irradiance level. The developed web tool performs automatic data acquisition of the open circuit Voltage (V OC ) from the solar panel, as well as temperature level measurement. Low cost microcontroller Arduino is the data acquisition device, it sends V OC measurements obtained from the solar panel, and temperature from a thermocouple. Data are sent by wireless connection into a web data base. After data are obtained, processed and analyzed performing the programmed calculations. Results can be shown in the Web platform as a table or as a graphic, depending on the user requirement, data are updated every fifteen minutes. Historical data are also available on the Web platform with some period of time limitations. Data can be consulted on different Operative System platforms, such as Windows, Android or iOS, it means data can be consulted even in mobile devices. The integration of low cost open source software and hardware tools was successfully done to build an automatic data acquisition system for Irradiance and temperature in-situ of the university campus.
