  传感器博览会:从无线传感器网络到数字温度传感器

  而无线传感器网络,能量收集,和MEMS技术–都具有一定的“哇”的因素–可能获得最大的关注,在最近的传感器博览会的展览,你不应该减少更多的商品–的重要性但急需的–部件如数字温度传感器。

  温度传感器变得越来越重要,因为设计师们试图尽可能多地将它们的组件塞入它们的板上,这通常会导致更高的热量产生,因此需要大大改进温度监控和管理。

  因此,当涉及到移动设备的温度传感器或者应用程序时,设计者们希望实现更低的功耗、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.
