Put this module in a little light-tracking bot project and it worked perfectly at 5V. The TTL output gives nice clean highs and lows even under a desk lamp. So far it's held up great in the 20°C range I've been testing.

The 3-wire hookup was dead simple even for a beginner like me, and the TTL output gave a clean, stable signal every time. I've had it running in my project for two weeks now, and the photosensitive diode responds instantly to light changes.

The 3-wire TTL output made wiring into my project a breeze, and it's been reading consistently at room temperature. For under 10mA draw, this little diode module is a solid little workhorse.
