An example of how a sensor clean should be. This is from a Canon 1D mk2N.
On the left, a dirty sensor. After a thorough clean the image to the right shows that it was successful.

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.

MOC: Sensor GTR. A variation of the theme from my previous Supercar - I wanted to see if I could build something a supercar that looked a bit more like it was meant for the road than for the track. Very happy with the result.
Camera sensor.. this is just a few millimeters across.
Taken with a reversed 50mm prime lens, taped securely to a filter adapter attached to my Canon S70.
My phone died recently. I think the charging circuit quit working, because it would recognize being plugged into power, but the battery never charged. It has since been replaced.
Agfa Optima 500 Sensor
Apotar - Paratic lens f= 42mm, 1:2,8
Auto exposure or B
35mm film
Here some example photos taken with it.
I will be using this camera in week 71 of my 52 film cameras in 52 weeks project:

The first year is documented in this book:
Sensor part of the FreeStyle Libre blood glucose monitoring system. This dedicated sensor is integrated on the main board inside the monitoring system. 42 photos are stacked using Zerene Stacker. The full width of the photo is approx. 15mm.
Camera: Nikon D850, ISO 64. Lens: AF Micro-Nikkor 60mm f/2.8D @ f/11 + 68mm Kenko extension tubes. Manual controlled microrail @ step-size 200um. Natural light.
This light sensor works reasonably well. Goodluckbuy list it as “Electronic Brick Light Sensor Brick Module” (SKU: 75283). That’s right brick is in there twice.
From what I could find I think made by Itead. The A-D switch lets you pick the type of output from the sensor. An analogue voltage or digital high/low. The switch point for digital is adjustable via the pot and the board uses an LM358 op-amp.
Programming and working out how to apply an analogue input value to automatically adjust an output brightness value for my series of 7-segment displays proved annoying and I had little success. I believe a lot more trial and error would be needed to make this and other displays adjust with the brightness of the room. Or perhaps I’m just a bit crap.

The Agfamatic 100 is a viewfinder camera for Pak-Film 126 cassettes. It has an Agfa Colorstar lens with fixed focus and fixed aperture. Two shutter speeds are selectable with the ring around the lens barrel, the scale showing a cloud and a sun symbol. The camera has a single stroke advance lever that advances the film, cocks the Parator shutter and turns the flash cube holder on which magicubes can be fired as flash. On the axis of the advance lever is the red "sensor", the shutter release button hidden under a round piece of red foil. A little black plastic button side on the side unlocks the back door for opening the camera. The back door has a window for making visible the film cassette's exposure counter. The camera has an optical bright frame viewfinder of reverse Galilean type
Arduino Heartbeat sensor circuit soldered together without a board. Later enshrined in electrical tape.

The advance lever double functions as rewind lever, after the rewind button is pressed.
This camera was made in Portugal
Sensors fitted with rubber washers and contour rings, you will need to select the correct contour rings to fit the countour of the bumper when fitting the sensors
Researchers at Pacific Northwest National Laboratory are conducting photo-induced gas-sensing studies to learn about the detection of gases. Shown, a small size vacuum sensor.

Combined acidity/chloride sensor complete with integrated wireless module, allowing the sensor output to be read out on a remote unit. Further size reductions are possible, leading to sweat sensors that are small enough to be integrated into an on-body patch as part of a body area network (BAN), allowing real-time monitoring of dehydration and electrolyte levels, helping people to balance their intake of fluid and salt. This would be especially useful for elderly people suffering from fever and diarrhea whom can become easily dehydrated.

This is an update of the previous picture. After a comment on the Eurobricks forum, this was pointed out to me. Now we see a light value between 0 and 100. the next byte is the color that was detected. So here 3 which corresponds to blue. This value is also shown when your Mindstorms program is active in the Mindstorms status screen on the top.
The official dust-and-oil photo check from the last time. Even less change from June to August than there was from April to June (if anything moved, it's probably because the shot is with a different lens than the ones I took all the others with).
Shutter count 7,166.
Sensor cleaner eyelead I think this one really works, in case you need to clean your sensor I highly recomend this over wet method
