Light Sensor Module Technical Data
The light Sensor module is a standard item now. It just provides an illuminance value. It is de-
signed with TPS851. This device enables low power consumption to be achieved.
• Little
fl uctuation in light current and high level of sensitivity
: IL = 37 μ A to 74 μ A @EV = 100 lx using fl uorescent light
: Light current variation width: ×1.67
(When light current classi
fi cation is speci fi ed.)
: Little temperature fl uctuation
• Built-in luminous-ef fi ciency correction function, reduced sensitivity variations due to vari-
ous light sources
: IL (using incandescent light)/IL (using
fl uorescent light) = 1.2 (typ.)
• Low supply voltage, making device suitable for battery-powered equipment: VCC = 2.7
V to 5.5 V
