Description
AS7331-AQFM is a spectral UVA/B/C sensor. It is a low-power, low-noise integrated UV sensor. The three separated UVA, UVB, and UVC channels convert optical radiation signals via photodiodes to a digital result and realize a continuous or triggered measurement. The irradiance responsivity can be adjusted via Gain, conversion time, and internal clock frequency to affect sensitivity, full-scale range, and LSB. The AS7331 detected amount of radiation in the set Gain and conversion time configuration will be provided as digital counts by the AS7331. The AS7331 offers a range of 12 Gain steps by a factor of two for each step. The conversion time is internally controlled over a wide range of 15 steps by a factor of two for each step. Application includes UV disinfection (water, air, surfaces), UV-curing, phototherapy, analytics, home appliances, and horticulture.
