Piccolo ed efficaci
Articolo che rispecchia quello descritto nella pagina. Da segnalare che la copertura in plastica che si trova nella parte superiore del sensore si stacca dalla sede con facilita' ma basta un po' di colla per ovviare al problema. Rispetto al fratello maggiore HC-SR501, l"AM312 ha un'angolo leggermente piu' stretto ma non di certo funziona male. Molto discreto puo' essere utilizzato in progetti dove lo spazio per l'installazione e' molto ristretto. Non e' possibile tramite hardware o software modificare tempi di funzionamento o sensibilita' o rimanere eccitato in caso di movimento. In pratica tale sensore funziona come un'interruttore...se qualcosa passa davanti lui da il segnale stop...

Perfect operation
Great little PIR sensor, great range and sensitivity. Works as advertised. all three worked.

Simple, easy to use sensor
Perfect for use with Raspberry Pi. Wide input voltage range, no adjustments. Output is always 3 Volts regardless of power supply. These will not directly drive an LED so if testing that way, use a 2222 or similar transistor. Sensitivity is better at 5V or higher than at 3V. All of mine worked right out of the package. I will build something to mess with the cat!

my opinion
This device works perfectly and responds shortly in more or less 2 seconds.
