Yesterday I was triyng to read the infrared impulses from my electricity meter. The phototransistor I'm using, can see the IR from all the remotes in the house... but doesn't read the blink from the electricity meter. I can see the IR blink of the meter with any camera, is bright and powerful enough. I wonder why the phototransistor doesn't see it?
I'm using this schematic to read the IR beam and, like I said, works with all other IR sources I found around the house:
**broken link removed**
Any ideas?
