Night Light

Functions:

Photo Transistor is an electronic component operates in Night Light to percept the intensity of light. It could be used in the control of Night Light reacting with the environmental background. The day arrived at dusk, When Photo Transistor induction to the dark, then open the Night Light; by night to dawn, When photosensitive IC induction to dawn, then Automatically shut off Night Light; The product has realized automatic adjustment, reduce the energy loss...

Testing:

1) The shorter lead is the positive.
2) Current is at 0.3 uA per lux
3) Vcc is at 5v
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.
