LX1972 Analog Light Sensor ELC1 It does have the RTCThe LX1972 is a low cost silicon light sensor with spectral response that closely emulates the human eye. Patented circuitry produces peak spectral response at 520nm, with IR response less than 5%, of the peak response, above 900nm. The photo sensor is a PIN diode array with a linear, accurate, and very repeatable current transfer function. High gain current mirrors on the chip multiply the PIN diode photo current to a sensitivity level that can be
