My new sensor for the Dexcom machine. It is twice as big as the infusion site for the pump and I do hope to get a picture of both things on my abdomen. I will have to keep them more than 5 inches apart though, and I am pretty particular about exactly where I am going to shove the needle in...so maybe a picture, maybe not. The Dex seems to work pretty well though, very interesting!
Ceramic samples: Alumina (two grades); Silicon Nitride; Aluminum Nitride; Boron Nitride. Each sample has a pellet of bismuth in the center.
A sheet of wNode boards. These boards are low priced, ultra low power, sensor transmitters.
You can plug in 4 sensors and the values are automatically transmitted back to the base station every hour.
This light sensor is saving energy in the library entrance since it only turns them on when they are needed.
Sensors are mounted on 2 inch square blocks of wood. The electronic bit on the side is the distance adapter, which interfaces between the actual sensor and the Phidgets interface board. See pingplatform.wordpress.com for more info.
Your monitor isn't dirty. Those flecks are on my D70's sensor. Verified with multiple lenses. Nikon Capture does an impressive job of removing these marks based on a dust off reference photo but I'd rather clean the sensor.
Glad to share first look of our new urinal sensor

This is the first DIY Wii Sensor "bar" that I experimented with. I don't think I'm supposed to end a sentence with the word with. I've done it again.
I figured I should take a couple pictures of this one since it is being disassembled and recycled into another new sensor bar model.
For a first attempt, this one worked rather well, though only having a single LED per side meant that it wasn't very forgiving when you weren't in the center, facing the screen head on.

It's times like these when you kick yourself for forgetting to get a sensor cleaner for the n-teenth time.
Mark (narrowcurves) created Sensor Enclosure in wonderful detail and then uploaded it using 3DVIA Composer. Check out the immaculate board components and wiring! That level of attention to detail makes a big difference when it comes to assembly. Very nice!
Here is where I tape the Fiber Op cable from my Pclix onto my camera. If you haven't guessed the IR sensor is right above the red area of the grip. If you use black tape, more than one strip is necessary to attach the cable to the sensor. The adhesive loses it's stick on particularly hot days.
Eindhoven is leading as one of the top smart cities in the world. Aside from sustainability plans, we lead big data research too. For example the Citybeacons, which offer city info at anyone's fingertips, while continuously watching and sampling the city with cameras and sensors.

Overview
PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. They are small, inexpensive, low-power, easy to use and don't wear out. For that reason they are commonly found in appliances and gadgets used in homes or businesses. They are often referred to as PIR, "Passive Infrared", "Pyroelectric", or "IR motion" sensors.

FAQ
1.How long do motion sensor lights stay on?
Most people set their motion detection lights so they will stay on for about one to two minutes.
2.Do motion sensors save electricity?
Motion sensing switches do have some “phantom” energy use. According to this study, motion sensor switches use about a watt of energy on standby mode (23 hours a day) and 5 watts on active mode (about an hour a day). This trims a bit off of your overall savings.
