## Description

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

## 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.

## Questions & Answers

**Q: Does this have a delay timer. what i mean is, if i use to light a small led on movement, will it power the led for more than a few seconds ?  thank u.**
A: There’s no delay timer built in to these and the trigger goes off after about 1 or 2 seconds. You could hook up to an arduino or something that could give you delay control. 555 timer perhaps, but this could be over complicating it :-)

**Q: I can’t get this to work.  can i plug direct into a fairy light display or do i need another part to make it work? thanks.**
A: the output is not designed to drive any meaningful current so you must put a high power FET on the output lead to drive low voltage fairy lights or connect as per the product page to an Arduino 2 and then use another output pin from the arduino to a relay board and use the relay contacts to switch the fairy lights. The software will be a straight forward loop to test the IR sensor for a high logic 1 input and then switch on the relay [output 1 to that port pin] else switch off the relay [output 0 to that port pin]. hope this helps Andrew

**Q: Does this pir switch at the same input voltage? ie 12dc in - 12dc out. thanks**
A: As Soon As I put 12v across one it blew. so I will be running them at 5v and using a transistor on the output to switch a 12v relay

**Q: can i make it only output as high if there is motion currently?**
A: sure, that's how it works
