“…It is important to point out that in the aforementioned works, the autonomy estimate is not made considering 100% battery charge, it is considered a charge of 60 to 70%. Regarding the degrees of protection of the sensor nodes, several related works do not specify the characteristics of the containers, however in the description of their research, boxes that provide protection to the sensor nodes [12,19,21,24,26]; while most research shows the importance of protecting the elements against environmental factors, which is why the design and 3D printing of waterproof casings that are coupled to the design of the sensor nodes is carried out [22,23,25,27] or these in turn are introduced in housings whose degrees of protection are defined by standard IEC60529 [17,20,28,29]. It can be concluded that all the works put a special emphasis in the development of the protection systems, to guarantee the optimal performance of its components conserving them within the specified characteristics for long periods of time.…”
