基于单片机的轴承温度传感器设计

Design of bearing temperature sensor based on Single-Chip Microcontroller

采用数字温度传感器LM75A配合单片机测温,通信接口使用了RS485芯片,E2PROM 24C02保存传感器的地址和波特率。电路结构紧凑,能够放到普通测温元件的外壳中,构成智能化RS485接口的轴承温度传感器。

Uses digital temperature sensor LM75A and Single-Chip Microcontroller measure temperature, communication Interface uses RS485 chip, address and band rate of the sensor is saved in E2PROM 24C02. The circuit＇s Structure is compact, it can be putted into a shell of normal temperature sensor, composite a intelligent bearing temperature sensor with RS485 interface.
