day/night sensor

[grounded]

Whats the option for a day/night sensor to be used as a input for a 16f630.
using PBP
this is for a joint hobby project with a out of state friend.
I'm programming the chip he's building the board
I have used the "pot" command with a LDR and cap which has most of the calibration in the program. I added a cal. pot but it has little effect. and I would hate have to mail the chip back and forth to get the cal. were we need it.
I've used a LDR, pot, voltage divider& transistor set up but this project is battery operated and I think it could be hard on battery life.
just wondering if there is a better option.
as always thanks

Look at the Panasonic PNA4603H.

Hi grounded,

Why don't you post your schematic here?

dhouston I did a search for panisonic could not find much.
sayzer here is a schematic
Sorry I'm a not a pro on this just a hobbist.
I guess in a nut shell what I need is a simple,cheap light sensor that has a wide range on the cal. pot, and is easy on the battery.

What do you need besides the PNA4603H data sheet which the first few hundred Google responses point to?

the smarts to understand them
sorry dhouston not trying to be a smart (*&(& . but I'm just a hobbist
I did look at the data sheet but that all greece to me. I'm not even shure what it or does
i need examples, people telling how they work ,why they work what they are.
schematics
sorry
