The log-EZ represents a simple and easy to use solution for measuring and recording temperature and humidity at homes or office buildings. These units feature wireless communication interface, enabling simple and easy data transfer to the PC, via "log-EZ for Windows" software. The wireless functionality completely dispenses with manual gathering of data loggers, or use of USB cable for data transfer. A single PC can be easily used to combine and view data obtained from multiple loggers, if it is connected to the Wireless Dongle. Additionally, the "log-EZ for Windows" software allows current measured and recorded temperature and humidity data to be easily viewed in graph form.
