TEMPERATURE MEASUREMENT SYSTEM FOR HARD DISK DRIVE

摘要

A temperature measurement system for a hard disk drive (HDD) includes a bipolar junction transistor (BJT) set inside the HDD, a temperature sensor, and a baseboard management controller (BMC) connected to the temperature sensor. A base of the BJT is connected to a collector of the BJT. The collector of the BJT is further connected to a first idle pin of a connector of the HDD. An emitter of the BJT is connected to a second idle pin of the connector of the HDD. The temperature sensor is connected to the first and second idle pins of the connector. The temperature sensor senses a voltage difference between the collector and the emitter of the BJT to obtain the temperature of the HDD. The BMC receives the temperature obtained through the temperature sensor.
