Operating between 2.7V and 12V, it features a 100Β° sensing cone with a 3-5 meter range and smart repeat triggering that extends output during continuous motion. Ideal for Arduino projects, security systems, and industrial automation, it comes with 5 sensors and a 15-pin Dupont wire for quick setup. ## Description Description: AM312 body sensors modules: A passive body based on the digital intelligent infrared technology, Automatic control products. High sensitivity, high reliability. Widely used in various auto-sensing electrical equipment. Features: - Immunity enhancement, internal use of digital signal processing, direct high-low output. - Repeatable trigger: the sensor output high after, the delay period, If there is human activity in its sensing range, the output will remain high until the people left after the delay, It becomes low (i.e. Sensor module detects the human body every activity will be automatically extended a period of time delay, and to the last activity time as the starting point of the delay time). Specification: 1. Working voltage: DC 2.7-12V 2. Static power consumption: less than 0.1mA 3. Delay time: 2 seconds 4. The blocking time: 2 seconds 5. Trigger: can be repeated 6. Sensing range: ≀100 degree cone angle, 3-5 m; (required depending on the lens) 7. Working temperature: -20 - + 60 ℃ 8. PCB Dimensions: 10mm x 8mm 9. Total size: Approx. 12mm x 25 mm 10. Module Lens: Small lens Package Included: 5 x Mini IR Infrared Pyroelectric PIR Body Motion Human Sensor Detector Module 1 x 15Pin Dupont Wire Female to Male Review: PIR's for any project - Great use for any project. I use these to know when my mail was delivered. This PIR detects the mailman and sends me a text to my phone along with a picture of my mail. Additionally with a ESP32 and Single 18650 battery cell in a 3d printed box. The ESP32 goes into deep sleep between messages and the PIR wakes it up. Just one of many uses for these devices. Review: All it needs is an actual data sheet from the manufacturer. - This compact pir module is working perfectly for the physical intrusion detection, alert, and interaction system I am building for a server room. I am currently running it at 5v. It would be nice to have a data sheet so I can determine the effect of modifying the voltages and amps supplied to the module. I have posted a picture of the arduino sketch I am using to determine how long the output pin remains high after detecting movement. If you can see the picture, feel free to use the code. Change the pin to the one you are using. ## Features - It is a digital intelligent automatic control product based on passive human body infrared technology. It has high sensitivity and high reliability and is widely used in various automatic induction electrical equipment. - Immunity enhancement, internal use of digital signal processing, direct high-low output - Low power consumption and small size for easy embedded installation. - Repeatable trigger mode: After the high level of the sense output, during the delay time period, if the human body is active in its sensing range, its output will remain high until the delay after the person leaves, Low level (i.e.: the sensing module automatically delays a delay period after each activity of the human body, and the last active time is the starting point of the delay time). - Widely applications: Security Products, the human body sensors toys, the human body sensor lighting, industrial automation and control, etc. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07XF62F9J | | Antenna Location | Security systems, Automated lighting, Toys, Industrial automation and control | | Battery Description | Battery not included | | Best Sellers Rank | #82,622 in Electronics ( See Top 100 in Electronics ) #330 in Motion Detectors (Electronics) | | Brand | DAOKI | | Color | AM312 | | Compatible Devices | Security systems, Industrial automation systems | | Customer Reviews | 4.3 out of 5 stars 73 Reviews | | Item Weight | 1.59 Ounces | | Manufacturer | DAOKI | | Maximum Range | 5 Meters | | Mfr Part Number | GR-US-026 | | Model Number | GR-US-026 | | Mounting Type | Embedded | | Operating Temperature | 60 Degrees Celsius | | Power Source | DC Powered | | UPC | 886769928096 | | Unit Count | 5.0 Count | ## Product Details - **Brand:** DAOKI - **Color:** AM312 - **Power Source:** DC Powered - **Item Weight:** 1.59 Ounces - **Maximum Range:** 5 Meters ## Images ![DAOKI 5PACK IR Human Sensor AM312 Mini Detector Module HC-SR312 Pyroelectric Infrared PIR Motion Automatic Detector DC 2.7 to 12V for Arduino 2 A1U2 with Dupont Wire - Image 1](https://m.media-amazon.com/images/I/61+Fzh6Qq6L.jpg) ![DAOKI 5PACK IR Human Sensor AM312 Mini Detector Module HC-SR312 Pyroelectric Infrared PIR Motion Automatic Detector DC 2.7 to 12V for Arduino 2 A1U2 with Dupont Wire - Image 2](https://m.media-amazon.com/images/I/51ohjqZiNOL.jpg) ![DAOKI 5PACK IR Human Sensor AM312 Mini Detector Module HC-SR312 Pyroelectric Infrared PIR Motion Automatic Detector DC 2.7 to 12V for Arduino 2 A1U2 with Dupont Wire - Image 3](https://m.media-amazon.com/images/I/51mqdfisNWL.jpg) ![DAOKI 5PACK IR Human Sensor AM312 Mini Detector Module HC-SR312 Pyroelectric Infrared PIR Motion Automatic Detector DC 2.7 to 12V for Arduino 2 A1U2 with Dupont Wire - Image 4](https://m.media-amazon.com/images/I/51xl3KazLUL.jpg) ![DAOKI 5PACK IR Human Sensor AM312 Mini Detector Module HC-SR312 Pyroelectric Infrared PIR Motion Automatic Detector DC 2.7 to 12V for Arduino 2 A1U2 with Dupont Wire - Image 5](https://m.media-amazon.com/images/I/61KUt-s5sWL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ PIR's for any project *by D***C on January 29, 2024* Great use for any project.

I am currently running it at 5v. It would be nice to have a data sheet so I can determine the effect of modifying the voltages and amps supplied to the module.

Change the pin to the one you are using. ### ⭐⭐⭐⭐ Works fine, though you may need spares *by T***K on August 25, 2023* I'm using these with ESPHome for some custom motion sensors I'm building. One was DOA straight out of the bag and ended up smoking when connected to 5v, but the next two were fine. It's worth noting you can't calibrate these, which may be an issue depending on the application, and it's possible the 90Β° angled pins might not be ideal. If you get this, be sure you have a spare or two for cases like these. ## Frequently Bought Together - DAOKI 5PACK IR Human Sensor AM312 Mini Detector Module HC-SR312 Pyroelectric Infrared PIR Motion Automatic Detector DC 2.7 to 12V for Arduino 2 A1U2 with Dupont Wire - 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 - Arduino Nano [A000005] – Compact ATmega328P Microcontroller with 22 Digital I/O Pins, 8 Analog Inputs, USB Connectivity, and Arduino IDE Compatibility for Prototyping and DIY 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.at/products/172637660-daoki-5pack-ir-human-sensor-am312-mini-detector-module-hc](https://www.desertcart.at/products/172637660-daoki-5pack-ir-human-sensor-am312-mini-detector-module-hc) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-06-04*
