基于红外技术的新型温湿度监控系统

摘要

文章利用半导体制冷技术并结合丙烯酸类树脂高分子材料吸湿特件,针对较小空间设计了一款新型温湿度监控系统,并采用红外遥控方式以方便用户的使用;该系统以SHT75高精度温湿度传感器为敏感元件和LPC1111单片机为控制核心元件,特氟隆耐高温屏蔽信号线的运用和采用不锈钢烧结网防护进气口,巧妙的软件编程和电路设计,使其能在恶劣条件下使用;文章详细叙述系统中温湿度控制环节设计方案、具体硬件电路与软件流程,以及相关测试,测试结果表明,系统运行稳定;该系统成本较低,生产工艺和制造设备简单,安全可靠,操作方便.%semiconductor refrigerant technique is applied. Which is combined with moisture absorption characteristic of acrylic resin . In the light of the smaller space, the paper presents the new temperature and humidity control system which apply infared techonology to enjoy the convenience of use . The system consists of the high - precision temperature and humidity sensor SHT75, the control core LPC1111, TELFON shielded cables with high temperature resistance and a stainless steel sintered protect wire mesh for air inlet, along with ingenious design of programming and circuit. Those ensure that the device can be applied in adverse environmental conditions. The article introduces the design of temperature and humidity control, specific hardware circuit . Software process and correlation test. Test results show that it runs stable . This system design with low cost, simple production process and manufacturing equipment > safe and easy to operate.
