Title The Design of Temperature and Humidity Monitoring System Based on MSP430 and NRF24L01

Abstract

Temperature and humidity are important parameters in environmental measuring through the ages. A large number of cables are needed in the traditional temperature and humidity test, especially those are controlled through the long distance. The cable wiring is complicated and is susceptible to corrosion and other effects. As a result, the presence of the temperature and humidity detection based on wireless sensor technology solved the problem very well.

The paper emphatically introduces the design and analysis of the temperature and humidity detection system, analyzes the working principle of temperature and humidity sensor module, uses MSP430 MCU for data acquisition and wireless sensing technology for data transceiver and realizes the visualization of the results finally. On this basis, the paper introduces the structural health monitoring briefly and the basic principle of piezoelectric sensor, designs a charge amplifier to enlarge the output of the piezoelectric sensor. At the same it is completes the experiment of piezoelectric sensor of temperature by using the temperature and humidity measurement system and the influence of temperature on piezoelectric sensor is finally validated.
