傳感器博覽會：從無線傳感器網(wǎng)絡到數(shù)字溫度傳感器

　　而無線傳感器網(wǎng)絡，能量收集，和MEMS技術(shù)–都具有一定的“哇”的因素–可能獲得最大的關(guān)注，在最近的傳感器博覽會的展覽，你不應該減少更多的商品–的重要性但急需的–部件如數(shù)字溫度傳感器。

　　溫度傳感器變得越來越重要，因為設計師們試圖盡可能多地將它們的組件塞入它們的板上，這通常會導致更高的熱量產(chǎn)生，因此需要大大改進溫度監(jiān)控和管理。

　　因此，當涉及到移動設備的溫度傳感器或者應用程序時，設計者們希望實現(xiàn)更低的功耗、更小的尺寸和更高的精度。

　　While smaller size and lower power requirements are self-explanatory， what is so important about higher accuracy？ Well， according to Analog Devices （ADI）， higher accuracy eliminates the need to average results， delivers faster data measurement， and improves energy efficiency and reliability.

　　For designers looking for extremely high accuracy， ADI has developed two digital temperature sensors that achieve a ±25 °C accuracy over a wide temperature range of -20 ° to +105 °C. ADI says these fully calibrated， 16-bit resolution temperature sensors can “cost-effectively” replace thermistors and resistance temperature detectors.

　　In addition， the high-precision， low-drift ADT7420 and ADT7320 devices offer ±0.5 °C accuracy over a -40 ° to +125 °C temperature range.
