- Page 2 Description The UVA sensor is an ultraviolet light sensor, which primarily responds to UVA radiation (approx. 320 to 390 nm). The UVA sensor is built around a broadband UV sensitive silicon photodiode. The diode produces a current proportional to the UV intensity. A wavelength selective filter limits light striking the diode to only the UVA region.
- Page 3 multiplying the UVB sensor reading by a factor of 40 index-cm /mW, but this is only an estimate. The UVA sensor reading cannot be used to estimate UV index. Examples of experiments • Measure the UV intensity as a function of time throughout the day. Do you need to worry about sunscreen at 8:00 in the morning? •...
