The Research of the CO2 Wireless Monitoring System Based on nRF401
As the development of carbon diocide sensors and communication technology, the method for monitoring the concentration of carbon dioxide is more and more advanced, especially the traditonal methods have the disadvantage of the low accuracy and inconvenience on use. This paper puts forward a wireless sensor networks based on nRF401 chip and the method of the signal transmitting. Through the application of wireless technology, the MCU could send the carbon diocide concentration data from the carbon diocide sensor which is based on the NDIR technology to the process module, and the system could achieve the distant measurement of the carbon diocide displayed on the LED. Comparing with wire monitor system, wireless monitor system omits linking lines and it has good application prospect.
