WSN-based Indoor Temperature And Humidity Acquisition System Design And Implementation

Environmental conditions of temperature and humidity indicators are important in many industrial settings parameters,development of reliable and practical monitoring system for temperature and humidity it is very important.Usually,the use of cable networks to monitor temperature and humidity,trouble with the wiring,equipment,free mobility is not strong. Existing wireless network systems,have the shortcoming of network instability,high transport cost.Wireless Sensor Networks,with self-organizing,rapidly deployable,highly shielded, unattended,etc.With the development of RF technology,integrated circuit technology,the realization of wireless communication have become increasingly vulnerable,data transfer rate is also getting faster and faster,and gradually reach a level comparable with the wired network level.In this paper,based on the WSN technology,wireless temperature and humidity monitoring program,do not have to the laying of cables,can save cost and time.Moreover, Changes in temperature and humidity measurement sensor node locations and increase or decrease in the number of sensor nodes are very convenient.Temperature and humidity used in the design of wireless sensor networks need to place the site of measurement sensor node, Monitoring Center by the acquisition of network data management and analysis,Monitoring Center by the acquisition of network data management and analysis.The wireless sensor network of temperature and humidity data will be transmitted to the base station of WSN, through the broadband transmission is sent to the mainframe data center,with rapid movement,and stable and reliable,good features such as maintainability,It can be expected, WSN has brought to mankind incalculable benefits.
