Functions:
Light sensors IC is an electronic component operates in Outdoor Display to percept the intensity of light. It could be used in the control of screen reacting with the environmental background. The internal dark current enables high accuracy over The full temperature range even at low light levels and with the sensitivity near the human eye photopic response

Testing:
1) The shorter lead is the positive.
2) Current is at 1.25uA per lux 3) Vcc is at 12v 4) Current=light intensity x(mA per lux).the output current can be converted to a voltage by connecting it in series with a resistor. 5) The position of installation and reflection of light will affect the ic greatly. 6) This is an analogue device with very linear light response range |
