Sunmaphore

Sunmaphore is an equipment designed to measure the "Ultraviolet Index"; a number that indicates the intensity of ultraviolet radiation that is relevant to health. The Measurment is done with UV filters and optical detectors. The Sunmaphore measures the UV index and turns on a colored light. The intensity of the UV radiaciation determines the color of the ligth, according to the suggestion of the World Health Organization (See table below). The purple hue is the most dangerous, while green means no risk. The color can also be used to estimate the maximum exposure to the sun without risk of skin burn.

Description  

The Sunmaphore has two main parts: The head and the viewer module, shown in the figure at right.

1  Head, which is the module that measures the radiation needs to be located in the sun all day.

2 The display module can be on the exterior or interior, in a visible position.

3  The display module must be plugged to the mains 220/110 V AC and automatically shuts down at night.

IMPORTANT. The head has a white teflon dome that should be cleaned periodically to eliminate dust that accumulates. Cleaning can be done with a damp cloth, pressing gently.

5. The Sunmaphore can be installed on a pole, as shown in the photo on the right. The head is located at the top of the pole.
