SEM320 UV temperature and humidity sensor is based on the principle that photosensitive elements convert ultraviolet light into measurable electrical signals. The integrated temperature and humidity sensor is integrated into one, and the measurement data is more comprehensive. The outer casing of the product is a wall-mounted high-protection enclosure with IP65 protection against rain and snow.
