Description

      The 413101 is used widely, the following is its 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". The 413101 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 of the 413101 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.
      The 413101 is a very good product. If you want to use it you must learn about it rightly. Here you can know that the 413101 has ten features. Please pay attention to them. The first feature of the 413101 is that it is near human eye photopic response. The second is high IR rejection integrated optical filter. The third is current output highly linear vs light level. The fourth is that it is 1uA per lux current output. The fifth is external resistor sets linear lux range. The sixth is that it has temperature stable. The seventh is that it has integrated high gain photo-current amplifier. The eighth is that it has dark-current cancellation. The ninth is that 413101 has digital output for on/off switching. The tenth is that the hysteresis to prevent flicker is close to switching threshold.
      The important features of the 413101 make it has many useful applications. Here give you four applications. The first is that the 413101 can applied in dawn or dusk sensing. The second is security lighting. The next application is night-lights. The third is LCD backlight control.
      There are also some functional descriptions about the 413101. The primary function of the 413101 is to convert light to an output current at ADJ pin. The source current from the ADJ pin is proportional to the illumination on the device, at approximately 1uA per Lux. The 413101 has additional circuits to provide a digital ON/OFF output at the DIG_OUT pin in response to the voltage at the ADJ pin. The current out of the ADJ pin will normally be converted to a voltage by a resistor between ADJ and ground. A 10K resistor would provide a 10mV/lux output voltage at the ADJ pin.
