It's times like these when you kick yourself for forgetting to get a sensor cleaner for the n-teenth time.
Sensores de fibra ótica são utilizados em vários tipos equipamentos de comunicação e interligados a plataformas conectadas, como instrumentos médicos de ressonância magnética.
I've added the white box to hide the private parts, as I couldn't set the photo to restricted since I'm not a premium member.
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.

New sensor arrangement. Having sensors in all four corners didn't get me all that much data, so here they are at 6" intervals along the radius of the pile.
What the piss happened to my sensor?! This has never happened before. I bought a cleaning kit and cleaned it myself. It took ages though. I hope this never happens again!
Our unique light sensor measures the intensity of the room's light and automatically calibrates the brightness of the image on the screen. In a sun-filled environment, the picture grows even brighter, and in dim surroundings, intensity is reduced. So now you're saving energy on a bright screen when it isn't needed. You're enjoying the best picture possible with a TV that's aware of its surroundings.
The resistivity of the water after filtration can be measured in the hundreds of MΩ—very close to theoretically perfect resistance for water. This machine records with two probes, just like a normal DMM.
