How to Automate a Haunted House Using Sensors

You've built a creepy haunted house and it's the scariest one around. How do you take it to the next level? Automate it using non-contact infrared photoelectric sensors to control electronic scare devices.

Haunted houses are designed to be very creepy and with enough volunteers, they may be loaded with frights around every corner. What if there are not enough volunteers available to haunt the house? Infrared photoelectric sensors are the perfect device to detect guests and to trigger electronic gadgets, such as noise makers or motorized animatronic characters, giving visitors a scare they won't soon forget.

Sensors are used every day in various industries ranging from food processing to automotive assembly lines. Some of the top commercial haunted houses in the country are now using the very same sensors to automate their haunted attractions, providing a far creepier presentation. Industrial sensors are available to the general public for less money than you might expect, giving the average Joe an opportunity to built a haunted house that rivals even the ones presented by major theme parks.

The easiest type of photoelectric sensor to use in a haunted house attraction is one that uses a mechanical relay switch. This type of sensor is as easy to wire and operate as a light switch. Also be sure that the photoelectric sensors use infrared light and do not display a visible light which would draw attention to them. Arrange the photoelectric sensors across from each other in a hallway or door jamb, or anywhere that a guest will pass between them. The guest will break the infrared beam of light, causing the mechanical relay switch in the photoelectric controller to close, which will provide power to a noise maker or animatronic device. Each time a guest passes the sensors, the same action will occur repeatedly without operator intervention. This allows volunteers in the haunted house to spend time mingling with the guests and not hiding behind walls, just making noise.

How to Detect Visitors in a Driveway Using Infrared Photoelectric Sensors

Sometimes you just need an extra minute to prepare for a guest’s arrival. When the doorbell rings, it’s often too late. Why not install a system that will alert you to the presence of a guest before they ever make it to your door?

Choose a quality set of industrial photoelectric sensors. Infrared photoelectric sensors may be used to detect objects in a number of ways. Mounting the sender and the receiver across from each other is known as a through-beam configuration and provides the strongest beam. Retro-reflective mounting places the sender and the receiver on the same side and bounces the infrared beam off an object when it is in close enough proximity. Diffuse proximity mounting uses the same layout as retro reflective, but also uses a reflector on the side opposite the photo eyes. Any of these three configurations may be used to set up a driveway monitoring system depending on what type of structures are adjacent to the driveway.

Evaluate the best location to mount the sensors. This may be a mailbox, a fence post, a brick building, a bridge, or whatever standing structure happens to be within range of the driveway. If you mount the photoelectric sensors in a through-beam configuration they do not need to be very close to the driveway, whereas the other two options will need to be much closer, depending on the type of photoelectric sensors used, like ten to fifteen feet

Trace a route back to your home for burying the sensor wires, but don't put the wires in the ground yet. Instead, extend the wires back to the house above-the-ground and connect the photo eyes to the appropriate power source or to an external amplifier if the photoelectric system includes one. Connect the output of the sensors to a buzzer or bell with a noise that is distinctly different from the sound that your doorbell or telephone makes so that you can easily distinguish them. Many photoelectric amplifiers include a relay output, so connecting them to a buzzer should be as easy as connecting a mechanical switch. See the manufacturer's website for wiring diagrams.

Test the system using different types of cars and trucks and also people. Adjust the sensitivity of the photoelectric system to the optimum level and mount the photo eyes at the right height from the ground to hit the midsection of most vehicles. When everything is set correctly, bury the conduit containing the wires and do your best to conceal the photo eyes from view. This system will provide a reliable means for detecting guests before they are standing on your doorstep and could also be interfaced with a security camera or lights. The opportunities are unlimited.

How to Know if Your Child Has Albinism

Albinism is a hereditary condition in which the body does not produce enough of the pigment, melanin. There are several degrees of albinism. One type affects the skin, hair, and eyes. Others may not affect all three. For parents who are unsure of what to look for, here are some helpful pointers.

Look for common signs of albinism. When babies are first born, it is difficult if not impossible, to immediately diagnose albinism when one or both parents have a light skin color. It is easier to diagnose in ethnic backgrounds where both parents have normally darker skin. Albinism is a static condition, so it is not crucial to diagnose it early. If a child has albinism, they will always have it, but the condition will not worsen over time. If a baby with albinism has a head full of hair when they are born, many people will quickly notice how light and how beautiful that hair is. In extreme cases, the child's eyes may appear to be pink, but normally, they will be blue or brown.

Watch for rapid back-and-forth eye movement. In the first few months, as your child becomes aware of their surroundings, look for rapid back-and-forth movement of their eyes when they attempt to focus on objects. If you do notice this, the condition is known as nystagmus and it is one indicator of albinism. Also, you may notice that your child tilts their head to the side and looks at things from the corner of their eyes. Talk to your child's pediatrician if you notice these things. They may refer you to a pediatric ophthalmologist for further testing.

Schedule an appointment with a pediatric ophthalmologist. The ophthalmologist will examine the child's eyes and look for things like transillumination of the iris, decreased visual acuity, or sensitivity to light. The true test that will determine the child's vision cannot be done until they are old enough to read an eye chart, but there are tests that may be done when they are very young to find a close estimate. One test uses white rectangular boards with printed lines on one end. The doctor will test the child to see if they notice the lines when the board is suddenly presented.

Have a genetic test done. If each doctor gives a diagnosis of albinism, you can have genetic testing done to confirm their findings. The results of the genetic test will help you to know the best way to care for your child and any precautions that should be taken. If the skin, eyes, and hair are all affected, the child will need very good protection from the sun at all times and limited exposure. Children whose skin is not affected may still have problems with their vision. Reducing glare in the rooms in your home and also in classrooms when they start school will help them to remain comfortable.

Contact organizations who support individuals with albinism and also parents of children with albinism. Do some research and you will find assistance in many areas. The most important thing to do is to treat your child just like any other child because they are just like any other child. Having albinism should not prohibit them from enjoying the same things as everyone else.
