基于单片机的室内温度报警装置设计

摘要

本文通过对单片机的室内温度报警装置，使用温度传感器DS18B20采集温度信息，实现检测、显示和监控的功能，并通过语音芯片完成录音报警功能进行分析，然后得到该报警装置具有电路简单、抗干扰能力强、功耗低、可靠性高等优点。%Based on the indoor temperature alarm device of MCU, this paper uses temperature sensor DS18B20 to collect temperature information, to realize the detection, display and control functions, and by the analysis of the completation of recording alarm function by voice chip, concludes that the alarm device has the advantages of simple circuit, strong anti-interference ability, low power consumption and high reliability.
