TSL230R Light to Frequency Converter


Vendor's Description: 


This thing is one of the most acurate light sensors I've seen.  You configure it by making pins 1 and 2 high or low to control it's sensitivity and make pins 7 and 8 high or low for the divider to make it pretty much able to speak to any microprocessor.

 Pin1|Pin2  sensitivity

0        0     off

0        1     x1

1        0     x10

1        1     x100

 

pin7|pin8   divider

0       0       1

0       1       2

1       0       10

1       1       100

You can just ground all these pins you plan on having off. Also, pin 3 is it's "output enable" pin that can just be grounded.

Supply 3.3V - 5V to pin5 , and your digital output is pin6.  On the 28X1 digital input, you can just do a count on a pin in a specified type slot and drop it in a word variable.

Very acurate device, but maybee too many pins to worry about.

What is up or down, do you mean high or low?

 

i guess he meant high or low as you can see from the tables, what else could have he meant? :=)

You could use it to detect AC light or to communicate with another robot using visible light (maybe), that's all i can think of!

You can also use it to detect micro changes in light by placing your finger on it and pointing an led at the tip of your finger.  This will show your pulse...
You should be able to do that with most light sensors although some will need amplification. This chip just has the amplifier buit in.
Yes, i meant voltage or no voltage on those pins.
