Sensing range: ≤100 degree cone angle, 3-5 meters; (depending on the specific lens) 7. Working temperature: -20 - +60 °C; 8.PCB dimensions: 10mm*8mm; 9. Module lens: small lens; Package Includes: 3* AM312 Mini Pyroelectric PIR Human Sensor Module

Review: 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...
Review: Ok - Los usé con Arduino. Funcionan bien y tienen buen rango.
