 How to measure UV Light
 -------------------------------------
 
-UV sensors like the [GUVA-S12SD](https://amzn.to/3jP4JCA) to the left, are Ultraviolet testers and outdoor ultraviolet detectors that use calibrated light sensing algorithms that can calculate UV Index. This type of sensors don't contain an actual UV sensing element, instead they approximate it based on visible & IR light from the sun
+UV sensors like the [GUVA-S12SD](https://amzn.to/3jP4JCA) to the left, are Ultraviolet testers and outdoor ultraviolet detectors that use calibrated light sensing algorithms that can calculate UV Index. This type of sensors don't contain an actual UV sensing element, instead they approximate it based on visible & IR light from the sun. This particular sensor measures ambient ultraviolet intensity in the 200 to 370 nanometer range, including solar ultraviolet UVA, UVB, and UVC light. This UV Sensor also provides a built-in amplifier with adjustable levels
