Review on Waveshare Digital LTR390-UV Ultraviolet Sensor (C) Ultraviolet Ray Sensing Ambient Light Intensity Measuring Direct UV Index Value Output I2C Bus by Andy Cornelison
Works great: Bulbs
I used this to test a couple of UV bulbs I bought to kill COVID-19 viruses. It turned out that several lamps sold as UV lamps were just normal black lamps and did not emit UV-C at all. To measure UVC, connect it to a 5V DC power supply and a digital meter. They aim the ultraviolet light directly at the sensor. Then cover the sensor with glass and measure again. If your light source is UVC, there will be a large voltage drop when measuring light through glass. Because glass blocks UV rays.
