UV-Ultravoilet Ray Detection Sensor Module

Automatic UV (Ultra violet) Ray Detection Sensor Modules

UV-Ultraviolet Ray Detection Sensor Modules are designed to measure ultraviolet (UV) radiation intensity in the environment. These sensors are widely used in weather monitoring, industrial safety, UV index measurement, flame detection, and medical applications. They can detect different UV wavelength ranges, from UVA (320–400nm) to UVB (280–320nm) and UVC (100–280nm), depending on the module type.
