Abstract According to the requirements for the multi-channel temperature and humidity acquisition,a temperature and humidity acquisition system with HMP155A sensor is introduced by using a low power consumption single chip MCU MSP430F149 as the core processor.The system design scheme,A/D converter,temperature-humidity acquisition and multiplex signal controller are focused introduced.The software design flow of the system is described in detail.The experimental results show that the system design is reasonable,reliable and stable.
