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 d...
