UV index signal light

UV index signal light Collect solar radiation and convert UV photons within the "skin sensitivity range" into electrical signals that conform to the World Health Organization and US EPA UV Index exposure categories. These exposure categories are determined by UV index signal light When the signal light is operating, the indicator light corresponding to the level of UV radiation received by the sensor will be lit.
The core component of the signal light is the erythema weighted sensor produced by Solar Light. For indoor signal light installations, the sensor can be set remotely, or the sensor can be mounted remotely or directly on the signal light for outdoor installations. Hardware for remote sensor mounting is available, as well as components used to mount the signal light on the wall and on the indicator pole.
On a clear summer day in the western United States, you can experience UV index values up to 10+. In the winter, higher values can be reached as well. That is, for a person with Type II skin, without protection, it can take 10-15 minutes to get burned. In the northwest United States, UV index values can reach 9+ during the summer and 3+ in the winter. These are usually average values.
