These camera based sensors manufactured by Computer Recognition Systems Inc. are sprouting all over the Royal Borough. The provide supplemental data to the main CCTV system, a system that is shared between local government and the Police. The code on the label suggests that this part of the system belongs to Thames Valley Police.
I have concerns about this, as the system is likely to be disproportionately more effective and useful in tracking unintentional/minor breaches of the law where the number plates are likely to be genuine, for instance slightly exceeding the speed limit or having an incompetent insurer that fails to make timely updates to their database. It's useless against a bunch of violent robbers who have switched stolen cars twice as they flee the scene of the crime, before driving home in their own cars which probably have cloned plates anyway. I don't drive, I just don't like to see my tax money wasted!

5 Lynxmotion Single Line IR sensors provide the input for detecting and tracking the line. Once adjusted these reliably present a logic high when on the line, low when off it.
The VOtect Sensor technology could save lives by detecting potentially explosive mixtures of hydrocarbon vapors in industrial plants, mines, ship bilges, and other areas where humans work. The technology won an R&D 100 Award in 1992.

Yay!! My sensor was getting so dusty...it was driving me nuts!
When cleaning your sensor, do NOT used forced air! You will only be pushing dust particles deeper into your camera and making more of a problem for yourself.
I highly recommend Nicholas of Copper Hill Images well documented method. Take your time and take care and you will be able to do it yourself.

The gauges are large, classic and easy to read (go figure) but the wheel is large and skinny. But isn't that part of the charm?
(Also try it on black.)
The latest version of my wireless temperature sensor using ATtiny84, RFM12B and DS18B20. Sitting on top of a 2 x AAA battery holder. With SD card for scale.
Pegado al riel, cumpliendo una silenciosa pero importante misión, un sensor de señal, detectando movimientos en la vía. Luego veremos que es lo que detectó este aparatito.
note sensor spots on right - the infamous D7000 oil splatter.
more appear with every shoot and the hurricane blower doesn't do squat to remove them. grrrrrrrrrr!!!!!!
Update 10/12: Using the Vdust sensor cleaners with some success.
Have used Vdust Plus and Smear Away kits. Vdust Plus removed most of the spots but two passes with Smear Away does a more effective job. The folks at Visible Dust recommend following up Smear Away with Vdust Plus in case Smear Away leaves any residual streaks but I haven't noticed any.
The oil spots keep reappearing and I have to repeat cleaning frequently. I recommend buying your sensor cleaners in bulk if you're having this problem!!! Doesn't look like Nikon has any intention of resolving this issue.
This prototype is the Urban Sensor Hack challenge entry of IoT Zürich Meetup and MechArtLab Zürich.
The idea was to build "timid sensor objects", a new breed of citizen sensors that try to look uninteresting and only reveal their sensors once in a while to take a measurement, then retract them again, a bit like a snail.
Using this strategy of camouflage, even delicate sensors could reside in places that humans can reach. Compare this to official sensors in the city which are always ruggedised and often placed out of reach to prevent damage.
The result is the "timid sensor egg", made from a tabletop trash bin, an Arduino, a Servo, two multi-colour LEDs, an LDR and a battery holder - all part of the kit. Plus a BlueSmirf Bluetooth module from Sparkfun. The egg measures brightness and talks to the Internet using a Bluetooth to Pachube Android app we built for another project.

This was created for Flaghead Photographic at a recent Triggersmart seminar. The PIR sensor picks up on moving heat signatures so we dropped warmed up vegetables into a nice Thai bowl to demonstrate this function as we couldn't get a wild animal into the studio!
There's a blog about the seminar here - www.dephotographic.com/blog/triggersmart-workshop-decembe...
Valeriy Ivanov, CEE Associate Professor, works to install sensors in the Amazon Rainforest outside of Santarém, Brazil on October 30, 2018.
Ivanov aims to collect water flow data from the trees to build a model that will help us gain an understanding of our push and pull on the region, and how it potentially affects the world’s climate.
