無線感測(cè)器已變得越來越普及，短期內(nèi)其開發(fā)和部署數(shù)量將急遽增加。而無線通訊技術(shù)的突飛猛進(jìn)，也使得智慧型網(wǎng)路中的無線感測(cè)器能夠緊密互連。此外，系統(tǒng)單晶片(SoC)的密度不斷提高，讓各式各樣的多功能、小尺寸無線感測(cè)器系統(tǒng)相繼問市。儘管如此，工程師仍面臨一個(gè)重大的挑戰(zhàn)：即電源消耗。

多遠(yuǎn)程二極管溫度傳感器-Design Considerations for pc thermal management Multiple RDTS (remote diode temperature sensing) provides the most accurate method of sensing an IC’s junction temperature. It overcomes thermal gradient and placement issues encountered when trying to place external sensors. PCB component count decreases when using a device that provides multiple inputs.Better temperature sensing improves product performance and reliability. Disk drive data integrity suffers at elevated temperatures. IBM published an article stating that a 5°C rise in operating temperature causes a 15% increase in the drive’s failure rate. The overall performance of a system can be improved by providing a more accurate temperature measurement of the most critical devices allowing them to run just a few degrees hotter.The LM83 directly senses its own temperature and the temperature of three external PN junctions. One is dedicated to the CPU of choice, the other two go to other parts of your system that need thermal monitoring such as the disk drive or graphics chip. The SMBus-compatible LM83 supports SMBus timeout and logic levels. The LM83 has two interrupt outputs; one for user-programmable limits and WATCHDOG capability (INT), the other is a Critical Temperature Alarm output (T_CRIT_A) for system power supply shutdown.
