## Overview

The HiLetgo AM312 Mini Pyroelectric PIR Sensor Module is a compact, energy-efficient motion detector designed for seamless integration into smart devices and security systems. Operating on a low voltage range (2.7-12V) and consuming less than 0.1mA, it reliably senses human movement within a 3-5 meter range and 100° cone angle. Its miniature 10x8mm PCB size makes it ideal for space-constrained projects, while its robust temperature tolerance (-20°C to 60°C) ensures consistent performance across environments.

## Description

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.
