Solar Shield
The solar shield is used to protect sensors, typically humidity and
temperature, from direct sunlight. Insert a sensor into one of the two
holes located on the underside of the shield. The shield provides a
friction lock so the sensors will not fall out. The sensors can be
removed by firmly twisting and pulling them out of the solar shield.
