无线温湿度数据采集板的设计

Design of Wireless Temperature and Humidity Data Collection System

介绍了一种以16位超低功耗控制器MSP430F149为核心的温室温湿度数据采集板设计方案,该采集板采用已校准数字信号输出的温湿度复合传感器DHT11,将采集到数据在液晶显示屏上显示,同时按固定协议通过ZigBee模块发送给路由节点,再由路由节点通过GPRS或者以太网传送给主机,以便随时查看温室环境的数据信息。

This paper introduces the design of temperature and humidity data collection system based on 16-bit low power consumption microcontroller MSP430F 149.The calibrated digital signal output temperature and humidity detector DHT11 is used in the sensor.It collects temperature and humidity data displayed on the LCD in real-time,which according to the fixed agreement is sent to the routing node by ZigBee technology,then to client by GPRS technology or Ethemet technology,in order to check the greenhouse environment data information at any time.
