It Consumer device 2 is easy to operate via a simple I C command. Industrial and medical application VEML3235SL incorporates a photodiode, amplifiers, and analog circuits in a single chip. The best spectral sensitivity Computing, and industrial devices and displays is used to closely capture real human eye responses. AMBIENT LIGHT FUNCTION VEML3235SL has excellent temperature compensation and the robust refresh rate setting does not need an external High ALS sensitivity with minimum detectable intensity of RC low pass filter. Software shutdown mode is provided, 0.0021 lux/cnt supports low transmittance lens design which reduces power consumption to be less than 1 A. Excellent temperature compensation VEML3235SLs operating voltage ranges from 2.6 V to High dynamic detection resolution 3.6 V. VEML3235SL can detect a wide range of ambient light power.
