Design Of Temperature And Humidity Data Acquisition System For Large Data Analysis

In the modern life, temperature and humidity is not only closely related to people’s production and life, but also is the main environment conditions in the chemical and agricultural production. Such as Heilongjiang, it has been many years that which is not to completely solve the food warehouse management, to supply vegetable cultivated by greenhouse, to control the management of farming transportation.Traditional humidity and temperature testing technology, especially for similar agricultural seed storage industry, which has been unable to meet the practical requirements.So how to break through and resolve to collect real-time temperature and humidity values, reading to obtain valid data, improve the management ability is very important.This paper design a wireless temperature and humidity monitoring acquisition system. It use multiple collection points, combine with wireless sensor network technology and increase the storage function. This system consists of two parts: a wireless temperature and humidity acquisition and a wireless receiver control system,which contain data acquisition, wireless data transmission, data storage, display modules. This article uses STC89C52 controls DHT11 sensors to collect data of real-time temperature and humidity. NRF24L01 wireless transmitter module? send out the data that has been gathered, then wireless receives and displays temperature and humidity data through LCD 1602,and AT24C04 store the data. In the end, the design will not only upload the data to the host computer through serial port, but also measured records based on the 4V characteristics of big data. In order to solve the problem of data-loss, this article adds EEPROM especially. Therefore the acquisition system to reach effective storage,guarantee resource acquisition and attain the original intention successfully.
