This UV Sensor is used for detecting the intensity of incident ultraviolet (UV) radiation. This form of electromagnetic radiation has shorter wavelengths than visible radiation. This module is based on the sensor UVM-30A, which has a wide spectral range of 200nm–370nm. The module outputs electrical signal which varies with the UV intensity. Application:- Suitable for UV Index Monitoring, DIY projects, UV-A Lamp Monitoring, Gardening, Environmental monitoring, Uv tester, uv index instrument, outdoor uv monitoring equipment, sterilization lamp, flame detection.
