Sensors are able to measure temperature, humidity, pressure, sound, light, magnetism, acceleration and various chemical properties in their vicinity. This installation illustrates how quickly and efficiently such sensors work.

Self explanatory. Showing that if the camera allows it one can almost fill the entire 4x5" film surface with shots taken with the GFX and then stitch them to a panorama. Something like what happens with the Gigapixel Gigapans.
Here's some before and after shots of my project to clean my sensor. As you can see in the before, it was a flippin' mess. In the after (though dark, sorry dreary day) you can see the lack of dust.
I used a Giottos Rocket Blower, 3 #2 Sensor Swabs and Eclipse liquid from Photographic Solutions, Inc., and the Sensor Brush from Visible Dust.
BTW, #2 sensor swabs don't actually come into contact with the XT's sensor unless you use them vertically. The Sensor Brush does a great job, but you really gotta get it charged up with static. They should make one with fuzzy slippers and carpet.
Balluff's new liquid-based inclination sensors measure the deviation on a horizontal axis of up to 360°. With an extremely high accuracy of 0.1°C, a resolution of 0.01° and a temperature drift of just 0.01% /10K, they are the ideal choice for solar -thermal power plant and renewable energy applications that require angle measurement or constant rotary monitoring.
BSI inclination sensors feature a robust metal housing with an IP 67 enclosure rating that is easily installed into systems with limited space due to their compact housing size. With an expanded temperature range of -40°C to + 85°C, they are ideal for outdoor applications.
The sensor is held in with a black plastic circlip. I'd read somewhere to use a cable tie to pull it out and to avoid losing it in the depths of the engine. In the end mine was quite solid and took quite an attack with a screw driver to get it out and as i'd bought a new one I probably wouldn't have minded if I'd dropped it.
Next I took the electrical connector off which had the usual squeezy bit at the top that clicks over to hold the connector in.
Uh oh - time to get the blower out, I think. These dust spots aren't causing too much of a problem yet,you can't really see them on normal photos, but it's probably time to give it a bit of a clean.
How to see how dirty your camera's sensor is:
1. Take a photo of a clear sky or other blank subject at f22.
2. Open the picture up Photoshop and run Auto-levels
Et voila, you can see just how dirty your sensor has got.

This sensor board dubbed "allinone" sports a nice selection of sensors for a very good price:
HMC5883 Triple Axis Magnetometer
BMA180 Triple Axis Accelerometer
BMP085 Barometric Pressure Sensor
TG3200 Triple-Axis Digital-Output Gyro
I will use this board together with the Seeduino Mega controller I purchased a while ago already. The firmware will likely be MultiWii, as it already supports this IMU. This will replace my current setup (ArduIMU+ v2 flat with a home-grown firmware).
The green thing is a proximity sensor that you'll see on most any thrill ride and in many other applications. A proximity sensor can detect a metal target in their sensing field (usually an inch away or so) using induction. They help the controller know where trains are located, what position the loading gates are in, if the brakes are open or closed, and other operational aspects of a ride.
Testing resolution & sharpness WIDE OPEN at speed boosted F2.0 with Viltrox speed booster on aCanon M50 Mark II. ISO400, hand held. The MC Beroflex 28mm F2.8 is amazingly sharp even wide open, and keeps up extremely well with the modern hi rez sensor. Hurray!!!! I focused on the grapes. Zoom in, and check out how amazing the texture is. ;
The MCA Cat III Workboat, owned by Aspect Land & Hydrographic Surveys Ltd, of Ayrshire.
The 'Marine Sensor' is road towable, and with a small forward cabin, can deploy from a slipway or boat hoist / crane and able to operate a wide variety of sensors.
Her hulls and catamaran configuration lend a fast transit speed and give good directional stability resulting in high quality survey data.

The guy at this table seemed annoyed at my being the "4th person" to ask if these were bend sensors. Can you blame me? Anyway, these were very cool. I could press the tip, of either of the left 2 sensors there (which were made of a very thin layer of something I didn't ask about) and watch the red and blue graph lines raise and lower on the monitor to the left of this image. I pressed smoothly and alternately harder and softer with both fingers and made the graphs dance in offset sine waves. It had a very fine resolution (seemingly far greater than 8-bit), no shivering or jumping, and according to Mr. Angsty, were quite durable, having been tested into the millions of presses, with only a very slight decrease in effectiveness, which is easily recalibrated for. They also had a chair loaded up with these things, through which were we treated to a rainbow display of one guy's buttocks pressures, akin to those seen in this buttocks pressures mapping, from the P.E.R.F.E.C.T. workstation. Oddly, the medical field is their biggest market, where they're used, for example, to test for things like blockages in implants.
Halo SMART Sensor detects signs of cigarette smoking or vaping. These could be in areas where CCTV cameras are prohibited and/or not suitable, but where you want them to make sure individuals are protected and illegal or unwanted behavior is recognized. With Halo SMART Sensor, you will have an auxiliary sensor that could help deliver alerts when students are experiencing bullying. Security Systems Texas could also detect when somebody becomes engaged in a fight. The Halo SMART Sensor can also help identify a wide variety of particles in the air so that it can help to prevent the spread of contagious diseases.
Just another shot of the sensor to let you see were it is. After I got the circlip off it took quite a bit of persuasion and WD40 to get the old one out of its holder. In the end I used a screw driver to prise it out.
After that it was fit the new one, top up the anti freeze and then refit everything.
I then used VCDS to reset the temp error codes
After getting off the bus, I was walking home and was about to round the corner to my apartment and I realized that finally I was out and about during sunset. I metered off the sky and I got this wonderful silhouette when I recomposed on the power/telephone lines.
