com 413101 Visible Light Detector with Analog and Digital Outputs DESCRIPTION The 413101 is a low cost 4-pin visible light sensor, with a current output which is directly proportional to the light level.
It has a built in optical filter to provide a response which is close to the human eye, or “photopic”.
It also has a digital output to provide on/off switching, with hysteresis to prevent flicker.
The output current can be converted to a voltage by connecting it in series with a resistor.
The dynamic range is determined by the external resistor and power supply (e.
g.
10K and 5V gives a range of 0 to over 250 Lux, but can be up to 1000 lux with a 1K resistor).
The internal dark current cancellation enables high accuracy over the full temperature range, even at low light levels.
FEATURES • • • • • • • • • • Near human eye photopic response High IR rejection – integrated optical filter Current output highly linear vs light level 1uA per lux current output External resistor sets linear lux range Temperature stable Integrated high gain photo-current amplifier Dark-current cancellation Digital output for on/off switching Hysteresis to prevent flicker close to switching threshold APPLICATIONS • • • • Dawn/dusk sensing Security lighting Night-lights LCD backlight control 1.
