Shop for PIR Sensor Alarms at SpiritShack! We have a wide range of PIR Sensors for ghost hunting. They use infrared light to detect motion and work perfectly in the dark. Our PIR Motion Sensors are slightly different; some come with and without lights and sound. The 360 Motion Tracking Puck, Flux 2, and the Ghostly Music Box are our most popular sensor alarms. The 360 Tracking Puck detects motion from every direction, and the Flux 2 from 2 directions. And the Ghostly Music Box is just one, but when it's triggered, it plays a creepy tune with a red light.

Knowing there are spirits in the house or building your ghost hunting in will ensure you know when it's worth exploring further.
Passive infrared (PIR) technology is used by countless paranormal investigators and there are a few different options to choose from.
Why PIR Sensors Are Popular for Ghost Hunting
PIR sensors work in conjunction with infrared radiation and act as a motion detector. If your paranormal investigative team isn't moving around and a PIR sensor is triggered, it could indicate there's another presence in the room.
PIR sensors are popular among ghost hunters because they work with energy, something spirits are known to manipulate. Using these motion detection tools is one of the easiest ways to prove there may be someone else in a room - someone you cannot see.
PIR sensors will sound an alarm or play music whenever the infrared light is disturbed, making it easy to detect activity. These are also some of the more affordable items you can add to your ghost hunting equipment collection.
Different Types of PIR Sensors
Let's take a look at some of the passive infrared sensors you have to choose from.
Motion tracking puck
This advanced motion detector has a 360° range, increasing your chances of tracking ghosts more accurately. Instead of just being able to track motion in a specific direction, motion is detected all around the tracking puck, allowing you to pinpoint exactly where a ghost may be spending the most time. Ghost hunters can also adjust the distance and sensitivity depending on the area of investigation.
When motion is detected, an alarm will sound and lights will come on, alerting you to a new presence. You can now use other devices such as a spirit box or EVP recorder to speak to the entity. As an added bonus, you can easily recharge the puck with a USB cable or use it with a USB battery pack.
Flux 2 Paranormal Response Device
Along with the Flux 2 having PIR motion capabilities, it can also be used to ask yes or no questions. Once a spirit is in range, you can ask your question. One of the two lights will light up, indicating a yes or no answer. Just remember to explain to any lingering ghosts whether the green or red light indicates yes or no. You will also have the ability to adjust the zone area as well as the sensitivity of the device
Paranormal investigators can also pair this session with an Ovilus if they want to receive more specific answers. Your Ovilus will use a word bank to relay the messages that an entity wants to pass on to you. This is one of the best ways to have an actual conversation with any spirits that may be hanging around.
Music box
If you want to give your investigations an eerie feel, consider using a ghostly music box to detect PIR motion. This popular ghost hunting tool is triggered whenever a ghost moves in front of it, causing it to play a spooky melody.
You can use this music box at any time of the day or night. However, make sure that you calibrate it ahead of time to ensure you aren't getting any false alarms. Should the music box keep triggering, you'll have more proof that an entity is present and can ask the necessary questions. This is the ideal time to use another device to begin the communication process.
Motion activated PIR sensor
This particular device is popular among ghost hunters and homeowners alike. If you've ever had a sneaky suspicion that your house might be haunted, this motion detector can help you prove it.
This motion activated PIR sensor is ideal for detecting PIR motion in larger areas - you can even use it outside thanks to the 7 to 10-metre range. The moment something moves within the sensor's 110-degree scanning area, it will sound a shrill alarm for 20 seconds, so there's very little chance you will miss it.
The alarm works with batteries and is easy to install, so anyone can use it. It also comes with a remote, so you can switch it off without waiting for the alarm to stop.
If you want even more proof of your ghostly encounter, try placing a camera in the area. A camera with night vision capabilities is highly recommended as it will increase your chances of capturing clear footage.
Para4ce PMB Poltertune
Another excellent PIR motion detector device is the Para4ce PMB Poltertune. It's small, light, affordable, and very accurate - so, it's no wonder it's widely used within the ghost hunting community. It's even used by famous ghost hunters like Zak Bagans.
This device works similarly to the music box. The minute an entity is within a 1–2-metre range, a red light will flash, and a spooky tune will begin to play. This is another device that will need to be calibrated before use.
PIR motion triggered sensor light
When your ghost hunting in the dark, it helps to have a PIR motion detector that incorporates lights. This PIR motion triggered sensor light will alert you to paranormal activity any time motion is detected, with the light staying on for 12 seconds.
This sensor light has a 120-degree motion-sensing area and can detect paranormal entities within a 4.9-metre range. Just be sure to bring some extra batteries along in case your set runs out.
Asking any spirits to activate the light to indicate their presence is a good way to start your investigation.
Spotting False Alarms
Even though a PIR motion detector can be an accurate ghost hunting tool, you will need to be aware of false alarms.
Your motion detector is highly sensitive to your environment, so it's important to be aware of your surroundings so that you know which alarm is real and which one might be false.
Make sure you aren't placing your motion detector near any open windows or heating systems that emit steam as this could trigger it. You also want to be sure that your team isn't walking in front of your sensors.
It really helps to place cameras in front of or around your motion detector sensors. This way, you can analyse whether an alarm is real or not. It also increases your chances of capturing ghostly footage that you can share with others.
Conclusion
If you're just getting started as a paranormal investigator, a PIR motion sensor is a great addition to your ghost hunting kit. They're affordable, easy to use and can bring your attention to any spirits that may want to communicate.
If possible, add different types of motion detectors to your investigation to see what works best. It will also give you a greater chance of catching paranormal activity.

What is a PIR motion sensor alarm?
A PIR sensor is known as a Passive Infrared sensor. It's often linked to an alarm that uses infrared radiation to detect movement within its range. The technology is used in security systems to detect intruders. But it may also be used in ghost hunting to detect paranormal activity.

How does a PIR alarm work?
A PIR sensor detects changes in the infrared radiation in its environment. When a person or object moves within the sensor's range, it detects and triggers the change in infrared radiation. Once triggered, a flashing light and or siren may activate. In ghost hunting, the idea is that the alarm will be triggered by a ghost or other paranormal entity moving within the sensor's range.

Can PIR sensor alarms detect ghosts?
The effectiveness of PIR motion alarms in detecting ghosts is a subject of debate. Sceptics argue that there is no scientific evidence to support the idea. And that ghosts don't emit or disturb infrared radiation. While believers claim that they have had experiences that suggest otherwise. It may depend on the user's beliefs and personal experiences.

How do you use a PIR sensor alarm for ghost hunting?
To use a PIR alarm for ghost hunting, you would set it up in a location that is believed to be haunted. And wait for paranormal activity to trigger the alarm. Some ghost hunters may use multiple PIR sensor alarms placed throughout a location. By using multiple sensors, you can detect movement from different spots at the same time.

Are PIR motion sensors dangerous for ghost hunters?
PIR motion sensor alarms are generally safe to use for ghost hunting. They do not emit harmful radiation or pose any significant physical danger. But it's vital to use them responsibly and with caution. They may startle or scare people who are unaware that they are being used.
