摘要
设计了一种低功耗便携式气象仪,该气象检测系统以低功耗MSP430单片机为主控,利用温度传感器、湿度传感器、气压传感器、风速和风向测量模块,进行温度、湿度、气压、风速、风向的测量;通过时钟芯片和12864液晶实现数据的实时显示;通过E2PROM进行数据的实时存储和查询。该气象仪具有小型化、实时化、低功耗和便携式等特点,测试结果表明该气象仪的测量精度可达普通气象测量要求,稳定性好,特别适用于小区域的气候监测。
A low-power portable weather instrument was designed. In this weather detection system, MSP430 MCU is used as master control chip, and temperature sensor, humidity sensor, air pressure sensor, wind speed and direction sensor are uti- lized to measure temperature, humidity, air pressure, wind speed and direction respectively. In order to achieve real-time data display, storage and query, the clock chip, 12864 LCD and EEPROM are used. The weather instrument has the characteristics of miniaturization, real-time, low-power consumption and portable unit. The test results show that its measuring accuracy can meet the requirements of ordinary meteorological measurement, and it has good stability and especially suitable for small region- al climate monitoring.
