I am trying to use a light sensor to control a simple circuit: battery, current limiting resistor, LED. How could I use this light sensor http://pewa.panasonic.com/pcsd/product/sens/pdf/ams.pdf without passing the current through it (and thereby cooking it)? Essentially the sensor would act as a good old CdS photo resistor or photo diode.
Battery is 3.7v and supplies 20ma to the LED.
