Good IR sensor, watch out for input voltage

Good IR sensor and good price for 5. Packaged well, all 5 work. Jumpers in the high/low settings and additional links to documents here would help earn a fifth star. The best documents I've found are by googling "Henrysbench HC-SR501 Arduino Tutorial and Guide" (Revain won't let me post a direct link). Two things worth noting: - Without changing jumper settings, they are set to high (repeating) mode - Running them even A BIT below 5V can result in repeated false alarms (i.e. "blink" on/off on the output signal).

Impressive
