摘要
本系统选用DS18B20温度传感器采集温度信息,采用STC89C52单片机做为主控芯片,处理并显示实时温度值。当温度超出预设范围便无线报警,可实现远程监控。该系统具有硬件结构简单、成本低廉、灵敏度高等优点。
This system takes advantage of the digital temperature sensor DS1SB20 collecting ambient temperature to single -chip microcomputer of STC89C52 as the core control components and throught digital display of thermomeler temperature. If the temperature is lower than the temperature we setting on wireless alarm device, then realize telecontrol. Therefore, this system has the hardware circuit structure is simple, low cost, high sensitivity and sighifican advantages.
