With such a configuration, the weather sensor 300 is wrapped through the protective cap 250 to protect the weather sensor, and water does not directly contact the humidity sensor 312 used for the weather sensor when measuring humidity. While it is possible to prevent errors that may occur, there is an advantage in that the response speed of the weather observation sensor 300 can be increased by allowing external air to circulate well into the protective cap through the vent 252 .

However, the protective cap 250 must be maintained at all times in a state exposed to the sun at 100%, and must also withstand heavy rain and heavy snow. Therefore, the protective cap 250 must have high water pressure resistance, and long life can be achieved only when it has resistance to ultraviolet rays, heat resistance, and cold resistance. If this is not the case, it must be replaced every time, and it takes too much replacement cost, replacement manpower, and replacement work time for maintenance rather than installation, resulting in great loss.

In addition, the pyrometric acid is added to contribute to softening so as not to be easily broken by suppressing heat shrinkage and securing tensile strength and flexural strength.

In addition, the 6-bromohexanoic acid is added to prevent moisture absorption and penetration of oxygen to prevent cracks and breakage of the coating layer to prevent deterioration. And, the polyamide-amine is added to maintain heat resistance and cold resistance.

In addition, the oxycarboxylate is added to enhance bonding strength by reducing voids due to adsorption between resin particles during mixing, and to increase heat resistance and cold resistance. In addition, the PEBAX (Polyether-block-amide) has a small change in hardness even at low temperatures, excellent fatigue resistance, and excellent molding processability due to its small specific gravity, as well as low hygroscopicity, bending fatigue resistance, weather resistance, flexibility, and creep resistance.
