The Confederation Mall has used Gyro Tech doors since the mid-90s. This mall specifically uses the GT 300. For such old doors, they use fairly new sensors... except for the sensor on this door.

The thing on the right is the sensor, it measures amps coming into your home to calculate watts.
The thing on the left is like a little NSA spy living in your home. It sends measurements for logging in Efergy's web site and opens a huge security gap in your local area network.
Update:
The system was working fine for the first six hours, and then stopped working altogether. Talking with Efergy it seems the problem happens when the hub receives a different IP on the local network. Apparently, the transmitter is paired to the hub via the hub's LAN IP. When the hub's LAN IP changes, you have to call in and push the transmitter button when they tell you to.
The solution is to assign a fixed IP to the hub's MAC address in your router.

When I picked up my 20D I thought it's care would be similar to that of my Panasonic FZ20. Keep it in a case... don't drop it, etc. Hmph.
Then in the last couple weeks I noticed some specks on my shots, and at first it wasn't a big deal, but as I've been looking for deeper depth of field these specks showed up more often. What was it? I started reading numerous posts on flickr about DUST being on an SLR's sensor. How to avoid it, what precautions to take - and then the discussion of CLEANING IT.
I took the camera in to have it's sensor cleaned. Hey - I don't want to scratch the thing that picks up light. $35, picked it up the next day and took some shots. Brought it right back and asked them to do it again. Took three times more in their shop before I left happier. Took some more shots and I was back to reading about the infamous and near fatal task of CLEANING YOUR OWN SENSOR.
If you want an opinion on anything you will find it with photography. If you want even more energetic 'chit chat' do a search on SENSOR DUST.
I thought about it and have read quite a bit on it - the sensor on the 20D's sensor has a protective filter on it. It's made of glass to according to numerous reads. I even found a page discussing how to replace this filter with another for infrared photography. This delicate little sensor, with a hardness of glass became less and less of a holy grail.
PLUS, I NEVER READ ANY POST FROM ANYONE THAT ACTUALLY SCRATCHED their sensor - just that it would cost an arm & leg to repair/replace.
I went with the Visible Dust product based on some discussions and a quick read on Luminous Landscapes.
I used a pure white image in photoshop as my subject to find the dust. Set the aperature to f/22 on my 50mm and snapped away.
First attempt at cleaning: No change.
Second attempt: Some dust gone, some dust either moved or added.
Third attempt: Dust gone to my satisfaction, at least at 10PM at night. I found that holding the brush at less of an angle and closer to 90 degrees worked better.
So, just some food for thought from an amateur photography hobbiest. If you're not comfortable in doing it then don't, but... So far so good here.
Sensor Module – Cambridge Graphene Centre/University of Cambridge (UK), Novalia (UK)
A multifunctional printed graphene circuit with breath sensor, touch sensors and strain sensors turns a pipe into a musical instrument. Printed graphene sensors can make everyday devices multifunctional. Simple, low-cost printed circuits will add functionality to a range of everyday items for smart interactivity.

Want to start playing with sensors, but don't know where to start? This kit includes a sensor for just about every job. With everything included in this kit, you'll be able to sense acceleration, distance, compass heading, vibration, humidity, movement, ambient light, temperature, and more! These are our favorite sensors from each category.
This is the hole where the wheel speed sensor plugs in. There are little teeth back there that, I guess, it can magnetically "feel" flying past it as the wheel turns.
I had to make a bracket to hold the speedo sensor that is rigid to hold the sensor 2mm from the gearbox flange lobes.I started with these two pieces of steel strip that I then welded together.
Aleta móvil situada en el borde de ataque del ala que cuando el ángulo de ataque es muy elevado la incidencia del aire sobre ella la desplaza hacia arriba, produciendo un contacto eléctrico que activa una luz roja y un zumbador de alarma en la cabina.
The U-shaped bracket includes an air pressure sensor that senses when the belt is displaced into this area. The sanding belt MUST be positioned into the U-shaped bracket when it’s threaded onto the machine - failure to position the belt Into the U-shaped bracket will destroy the belt when first powered on. This air pressure sensor then activates the tracking system which pivots the upper roller sending the belt in the opposite direction. If the air pressure sensor on this mechanism is too low, it will not sense the belt moving into this area, and the result will be the belt continues sideways into the U-shaped bracket tearing the belt.
You can see the sensor on the wall. The five-legged starfish really gets going when movement is detected, and the screen comes alive, too.
