This is a system for humidity and temperature data monitoring. The purpose of the system is to demonstrate the real-time data monitoring and collecting based on client-server architecture. The used sensors are developed at the Laboratory of Embedded Systems (LAB2104) at Technical University. The sensors implements their own WEB based interface for stand alone monitoring. Sample interface of the sensors can be found on the following link: demo sensor. You can find more information about the system at the WEB site of the laboratory. Also you can order hardware modules and sensors from the official production company - Hardware Group Bulgaria.
     The database server is hosted at the server room of the University. The sensors uses DHT22 modules. Communication uses middle gateway using simple PIC based microcontroller. This microcontroller implement algorithm for data analyze. It averages the sampled values by excluding the minimal and maximal values. The other values for specific interval are meaned. Also the controller suppots the XML output for the status variables: XML output
