Working voltage: DC 2.7-12V; 2. Static power consumption: <0.1mA; 3. Delay time: 2 seconds; 4. Blocking time: 2 seconds; 5. Trigger mode: repeatable; 6. Sensing range: ≀100 degree cone angle, 3-5 meters; (depending on the specific lens) 7. Working temperature: -20 - +60 Β°C; 8.PCB dimensions: 10mm*8mm; 9. Module lens: small lens; Package Includes: 3* AM312 Mini Pyroelectric PIR Human Sensor Module Review: Perfect operation - Great little PIR sensor, great range and sensitivity. Works as advertised. all three worked. Review: 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! ## Features - Working voltage: DC 2.7-12V. - AM312 Human Sensing Module: Based on passive body infrared technology digital intelligent automatic control products, high sensitivity, reliability, widely used in various types of automatic induction electrical equipment. - Low power consumption and small size for easy embedded installation. - Sensing range: ≀100 degree cone angle, 3-5 meters; (depending on the specific lens) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07RT7MK7C | | Antenna Location | Walkway | | Battery Description | battery not included | | Best Sellers Rank | #32,865 in Electronics ( See Top 100 in Electronics ) #134 in Motion Detectors (Electronics) | | Brand | HiLetgo | | Color | White | | Compatible Devices | Light, Security System | | Customer Reviews | 4.1 out of 5 stars 247 Reviews | | Item Weight | 0.32 Ounces | | Manufacturer | HiLetgo | | Maximum Range | 5 Meters | | Mfr Part Number | 3-01-1511 | | Model Number | 3-01-1511 | | Mounting Type | Tabletop | | Operating Temperature | 140 Degrees Fahrenheit | | Power Source | DC Powered | | Temperature Range | 8E+1 Degrees Celsius | | Upper Temperature Rating | 60 Degrees Celsius | ## Product Details - **Brand:** HiLetgo - **Color:** White - **Item Weight:** 0.32 Ounces - **Maximum Range:** 5 Meters - **Power Source:** DC Powered ## Images ![3pcs AM312 Mini Pyroelectric PIR Human Sensor Module PIR Infrared IR Sensor Body Manual Motion Infrared IR Detector - Image 1](https://m.media-amazon.com/images/I/51a2ZzDrFpL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect operation *by R***D on October 19, 2024* Great little PIR sensor, great range and sensitivity. Works as advertised. all three worked. ### ⭐⭐⭐⭐⭐ Simple, easy to use sensor *by S***S on May 25, 2021* 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! ### ⭐⭐⭐⭐ Functional Detection *by M***. on February 5, 2026* Works Fine. The output pin wouldn't drive my LED bright enough, so just added an external transistor driver as shown. Decent performance for the price. Was able to detect motion (for my application) up to ~8ft, any more than that resulted in inconsistent detection. ## Frequently Bought Together - HiLetgo 3pcs AM312 Mini Pyroelectric PIR Human Sensor Module PIR Infrared IR Sensor Body Manual Motion Infrared IR Detector - HiLetgo 3pcs HC-SR501 PIR Infrared Sensor Human Body Infrared Motion Module for Arduino Raspberry Pi - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/134944430-3pcs-am312-mini-pyroelectric-pir-human-sensor-module-pir-infrared](https://www.desertcart.be/products/134944430-3pcs-am312-mini-pyroelectric-pir-human-sensor-module-pir-infrared) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-07-09*
