A live juvenile fish (left) and the previous version of the Sensor Fish (right) are shown side-by-side as they’re exposed to a simulated dam turbine environment. This test helped PNNL researchers correlate the injuries some fish experience with the Sensor Fish’s measurements.

JPGs straight out of camera using Nikon's NATURAL colour profile. The old CCD sensors have been said to be more filmic (if not noisier) and this is the Nikon D60, and Old DSLR which was first announced back in Jan 2008 (a 15 year old camera)

Hi everyone...I was "smart" enough to listen to my friend who mentioned that it would be a good idea to use compressed air to clean the sensor...This is the result...took a snap of a white sheet of paper and noticed this crap was on there!!!
Obviously I went absolutely crazy!!! The stuff wouldn't come off...wouldn't evaporate and I was scared if I left it there too long it would burn a hole through the sensor filter and damage the sensor...so I did the most unspeakable act....

brace yourself...

I TOUCHED THE SENSOR!!!
I took out the softest thing I had at the time - my Spudz lens Cloth (I was out at the time) and wrapped it round the end of a pens ink tube and gently cleared it off...Its still there around the sides but it doesn't show up in pics anymore which is good...thank goodness it didn't scratch it!
No place near here cleans sensors so I just got a proper sensor cleaning kit which should *hopefully* arrive tomorrow morning...will clean it properly then...
Can you feel my pain?!
(Picture is of entire sensor uncropped...thats how bad it was)

Scintillating glass optical fibers are the first viable medium for large-area, solid-state, thermal neutron sensors that have applications in national security, medicine and materials research. Here, ultraviolet-induced fluorescence mimics scintillation.

Optical "Super Sensor" for the Phototrigger. Working in daylight at 30m
using laser pen.
Thanks to William Watling for the idea
T-stuk gebruikt om temperatuursensor met duikhuls in de waterstroom te krijgen. Dat reageert veel directer dan de sensor tegen de leiding monteren.
Er is nog voldoende ruimte tussen huls en binnenwand van de leiding om het water ongehinderd te laten stromen. Zie ook de Note.
RE_BEAM ROBOTS: Taller de construcción de robots
01.03.2014 12:00h - 16:30h
Lugar: Lab (1º planta / 1st Floor)
Taller de iniciación para la construcción de robots capaces de seguir la luz, utilizando en lo posible materiales reciclados (motores y sensores de viejos juguetes, aparatos, etc.) a partir de conceptos que electrónica analógica.
Este es el sensor MiniLink. La cánula va bajo la piel y la parte de atrás se conecta al transmisor que envÃa la señal vÃa radio frecuencia a la Bomba Paradigm Real Time.
Staff from the Center for Operational Oceanographic Products and Services personnel install a microwave radar water level sensor on the Dog River Bridge in Mobile County, Ala. This is one of five stations installed to support the county's storm surge monitoring network established in 2011.

Since the conductor sensors clamp onto the overhead groundwires, the Electric Power Research Institute had to custom design the sensors to fit Western’s lines. (Photo by Ross Clark)
2022 Mickey Leland Research Associate Mychal Amoafo working in the lab with mentor Larry Shadle. Mychal is working on the Advanced Systems Integration Team and his project is Intelligent Sensors for Control. In this research, typical process data is analyzed in real time and used to infer other process factors: information from the associated chemistry and physics that can then be used to improve sensitivity, control, process stability. For example, a flame temperature sensor for the Hyper combustor based upon calculating the adiabatic flame temperature. Once this is calibrated against the process response, then we can determine the real-time equivalence ratios, flows, and heat fluxes. In the thermal energy storage model it will give us the driving force for the energy input and then the wall temperature can be used to characterize the inventory of stored energy. Approaches including PCA (Dynamic or sampled, unsupervised) and neural networks (supervised) will be applied for dimensionality reduction and fault detection. We can force neural networks to do dimensionality reduction by designing encoder (or even an autoencoder) and decoder network. The encoder will reduce the dimensionality and we can analyze this reduced dataset for insight into fault detection. The student may use python to obtain initial results and reproduce in MATLAB if time is still available.
Look what came in the mail today! Don't know if it works, I only got it because it came with an older camera I wanted.
Takes 35mm film, uses two AA batteries, and says "Made in China" on the bottom.
I have been very bored today, so I got out my digital camera to take photos of some film cameras.
IR sensor voor Fischertechnik kogelbaan. De IR sensor kan werken op 5V en op 9V. Hij is niet gevoeilig voor omgevings licht. Zelfs getest in volle zon blijft hij correct werken. Het stroomverbruik door de IR diode is ongeveer 9mA en de load voor de Phototransistor is 5 mA. Burst van kogels worden mooi verwerkt. Ook getest met de TXT Controller Fischertechnik en 9V voeding.

Learned this test from a friend of mine Mr. Wail A. T. Tarabzouni. Here is how you can test your sensor.
use a lens that can give you f22.
here are the steps.
1. put lens to f22
2. aperature mode for normal expsoure
3. defocus the focus in manual focus mode.
4. any wall with uniform color. wave your camera around it during exposure.
as you can see i have lot of spots on the sensor. next step ill be learning how to get that cleaned.
Then, put the cleaner head on the sensor to vertical gently to remove dust.
I was afraid to use it, but it worked great.
