基于MSP430F149的温湿度传感器DHT21（又名AM2301）控制程序。 说明：空闲时单片机处于LPM3,若串口收到有效命令唤醒单片机开启采集，温湿度值以字符形式发送到串口，用串口调试助手即可观察。-Temperature and humidity sensors based on MSP430F149 DHT21 (also known as AM2301) control procedures. Note: when the MCU is in idle LPM3, if the

该驱动程序，是am2301和bmp180的驱动程序以检测大气的温湿度(Atmospheric pressure, temperature and humidity are detected)
