Cambridge CMOS sensors introduces the CCS800 product family of ultra-low power miniature gas sensors
5/23/2014
Cambridge CMOS sensors announces the launch of the CCS800 product family of ultra-low power miniature gas sensors, enabling a new generation of environmental sensor solutions. The CCS800 product family can be used for detecting Ethanol (Alcohol) and hazardous gases such as Carbon Monoxide (CO) and a wide range of Volatile Organic Compounds (VOCs) including Formaldehyde, and is supported in a ultra-compact SMD package.
Our patented CMOS MEMS Micro-hotplate technology provides a unique silicon platform for our CCS800 product family of gas sensors, enabling sensor miniaturisation, significantly lower power consumption, and ultra-fast stabilisation and response times.
The Micro-hotplates are suspended in a high reliability membrane and act as heater elements for a metal oxide (MOX) based sensing material. The material resistance will change due to reactions to selected gases and concentrations at temperatures typically between 200ºC to 400ºC. Through enabling very fast cycle times, advanced temperature modulation techniques can be used to ensure maximum sensitivity, stability and gas selectivity, and to minimise measurement times.
Traditionally, MOX gas sensors are big, expensive, high power consumption and suffer from the following limitations:
Cross Sensitivity - Non-specific and react to a multitude of gases
Drift - Baseline and sensitivity will vary from sensor to sensor and over time
Stabilisation - Time to reach a stable baseline is hours to days
To counter these limitations expensive and frequent calibration is normally required. In addition expensive filters are required to reduce cross sensitivity.
Through our unique technology, the CCS800 product family offers:
Outstanding Miniaturisation - 0.99mm x 2.0mm x 3.0mm SMD package as standard
Ultra-lower power - >95% reduction in power consumption vs traditional MOX gas sensors
Cross Sensitivity and Stabilisation - by enabling very fast cycle times, advanced temperature modulation techniques can be used to ensure maximum sensitivity and stability to a target gas, and minimise measurement times.
This enables the use of our gas sensors in application areas that have not been physically possible before now, such as, smartphones, tablets and wearable devices.
Paul Wilson, Product Marketing Director at Cambridge CMOS sensors said, "Sensors are the fastest growing area of innovation in Smartphones, tablets and accessories. The CCS800 product family is the world's smallest and lowest power MOX gas sensors. They enable compelling use cases for monitoring indoor air quality including Carbon Monoxide (CO) and a wide range of Volatile Organic Compounds (VOCs), protecting you and your family from invisible danger"
Availability
The CCS800 product family is available in three variants, which are sampling now.

The Federal's pistol slid into its holster and his sabre flashed out. He threw its curved point up in a splendid salute. Ferry saluted with his straight blade. Then both swords rang back into their scabbards, and Jewett whirled away toward his column. For a moment we lingered, then faced to the left, trotted, galloped. Over the fence and into the road went he--went I. Down it, as we crossed, the blue column was just moving again. Then the woods on the south swallowed us up. "All right, sir." that before. Meanwhile the parallelism between Thought and Extension was not exhausted by the identification just analysed. Extension was not only a series of movements; it still remained an expression for co-existence and adjacency.412 Spinoza, therefore, felt himself obliged to supply Thought with a correspondingly continuous quality. It is here that his chief originality lies, here that he has been most closely followed by the philosophy of our own time. Mind, he declares, is an attribute everywhere accompanying matter, co-extensive and co-infinite with space. Our own animation is the sum or the resultant of an animation clinging to every particle that enters into the composition of our bodies. When our thoughts are affected by an external impulse, to suppose that this impulse proceeds from anything material is a delusion; it is produced by the mind belonging to the body which acts on our body; although in what sense this process is to be understood remains a mystery. Spinoza has clearly explained the doctrine of animal automatism, and shown it to be perfectly conceivable;569 but he has entirely omitted to explain how the parallel influence of one thought (or feeling) on another is to be understood; for although this too is spoken of as a causal relation, it seems to be quite different from the logical concatenation described as the infinite intellect of God; and to suppose that idea follows from idea like movement from movement would amount to a complete materialisation of mind; while our philosopher would certainly have repudiated Mr. Shadworth Hodgson’s theory, that states of consciousness are only connected through their extended substratum, as the segments of a mosaic picture are held together by the underlying surface of masonry. Nor can we admit that Spinoza entertained the theory, now so popular, according to which extension and consciousness are merely different aspects of a single reality. For this would imply that the substance which they manifest had an existence of its own apart from its attributes; whereas Spinoza makes it consist of the attributes, that is to say, identifies it with their totality. We are forced, then, to conclude that the proposition declaring thought and extension to be the same thing570 has no413 other meaning than that they are connected by the double analogy which we have endeavoured to explain. “Oh, he’s welcome to it,” Sandy cried. “I’ve turned over a new leaf!” “But—are they?” He pulled a wire out a trifle from the sheath. The sergeant spent more time upon the oaths with which he embellished the counter-question as to how he should know anything about it, than would have been consumed in a civil explanation. "Doctor, he can't die. He mustn't die," said Shorty in agony. "The regiment can't spare him. He's the best soldier in it, and he's my pardner." AND ENTERS UPON HIS PARENTAL RELATIONS TO LITTLE PETE SKIDMORE. "Holy smoke, look there," gasped Monty Scruggs, as a company of rebel cavalry came tearing over the hill in front, to the assistance of their comrades. "That's about it," answered Shorty disdainfully. "That's the way with all cavalry, dad-burn 'em. They're like a passel o' fice pups. They're all yelp and bark, and howl and showin' o' teeth. They're jest goin' to tear you to pieces. But when you pick up a stone or a club, or git ready to give 'em a good kick they're gone, the devil knows where. They're only an aggravation. You never kin do nothin' with 'em, and they kin do nothin' with you. I never kin understand why God Almighty wasted his time in makin' cavalry of any kind, Yank or rebel. All our own cavalry's good for is to steal whisky and chickens from honest soldiers of the infantry. The infantry's the only thing. It's like the big dog that comes up without any special remarks, and sets his teeth in the other dog. The thing only ends when one dog or the other is badly whipped and somethin's bin accomplished." "Mmm." Reuben started out of the half-waking state into which he had fallen. It was late in the afternoon, the sunlight had gone, and a wintry twilight crept up the wall. Maude the dairy-woman was looking in at the door. It was about a month subsequent to this, that one morning, as Turner was making the anvil ring with the ponderous strokes of his hammer, two retainers from the castle entered the shed, and delivered an order from De Boteler for his immediate attendance. Wat laid the hammer on the anvil, and, passing the back of his right hand across his forehead, to clear away the large drops that stood there, looked with a kind of smile at the men as he said, HoME泷泽萝拉四部和集下载
