A remote monitoring system of temperature and humidity based on OneNet cloud service platform

As the development of economic and technology, Internet of Things (IOT) has become an important part of strategic emerging industries, this paper takes into account, small equipment, large coverage area, network data security, low power consumption and so on, A remote monitoring system of temperature and humidity based on OneNet cloud service platform is proposed. The STM32F103RCT6 of ARM Cortex-M3 kernel is adopted as the main controller, SIM800C communication module based on authorized frequency band GSM/GPRS cellular communication technology is used, Combining digital temperature and humidity sensor SHT20, real-time and accurate data acquisition is achieved. At the same time, data is uploaded to the Internet of things OneNet cloud service platform through the EDP protocol. Equipped with WEB services and terminals APP can look at temperature, humidity and power voltage data at anytime, anywhere on the computer, mobile phones and other mobile devices. In order to make users obtain the threshold data information in time, the development adds the trigger function in the cloud server, it makes the product more convenient and intelligent.
