The user-friendly log-EZ can be easily used to measure and record temperature and humidity in various places such as homes and office buildings. It is possible to manage data recorded by multiple log-EZ units, that are placed in distant rooms, via one computer. Also, wireless communication makes data transmission easy and simple with no need for cables or gathering the log-EZ units to collect data.
Simple and Easy Data Collection via Wireless Communication
Download recorded temperature and humidity data from the log-EZ to your PC via wireless communication.
Data recorded by the log-EZ can be downloaded to a PC on which the dedicated software "log-EZ for Windows" has been installed. The wireless communication function releases you from the burden of physically gathering the data loggers to check or collect data, or connecting the logger to your PC with a USB cable. Also, data recorded by multiple log-EZ units can be viewed via one computer which has the Wireless Dongle connected to it.
Easy Checking of Data in Graph Form
View current readings and previously recorded data in graph form.
Temperature and humidity data measured and recorded by the log-EZ can be monitored in a graph on a PC in which the software "log-EZ for Windows" has been installed.
While the following window remains open and in view, the graph will be refreshed at the set interval. The current readings, today's high and low readings will also be refreshed along with the graph. This refresh interval setting can be changed freely between one and sixty minutes.
Automatically Download Recorded Data
If the installed "log-EZ for Windows" stays on your PC as a resident software, it automatically downloads recorded data from the log-EZ at a set time of day (at 12:00 by default).
Recorded data can also be downloaded manually for a specified number of days (from one to ten days) before the current time.
Data downloaded to your PC can then be viewed in graph form for the selected Remote Unit and period of recording.
After viewing the graph, it is also possible to save data as text (CSV format) for use with common spreadsheet software.
Printing the Recorded Data
By clicking the [Print Preview] Menu from the above window, you can print the currently displayed graph from your printer.
Temperature and humidity monitoring and management across multiple rooms in a house with up to 16 log-EZ units
It is possible to manage a total of 16 log-EZ units with one computer to which the Wireless Dongle is connected. Furthermore, setting up Repeater(s) will help to expand the wireless communication range, enabling the viewing of temperature and humidity measurement in distant rooms.
What are “Base Units”, “Remote Units” and “Repeaters”?
When explaining about wireless communication, the log-EZ is referred to as a "Remote Unit" and the Wireless Dongle for connecting to a PC as a "Base Unit". A "Repeater" is defined as a device that is placed in the wireless communication system to relay communication between a Base Unit and a Remote Unit.
* The dongle can be used both as a Base Unit and a Repeater, but it does not have a measuring function.
Adding or deleting Remote Units and Repeaters can be carried out from PC, therefore it is easy to increase measuring points. There is no need to make settings on the Remote Units and Repeaters themselves.
By setting the Wireless Dongle or a log-EZ as a Repeater, it is possible to extend the wireless communication range.
Communication Route Figure
By assigning names to each Remote Unit and Repeater in the communication route (such as "stairs" or "1F lobby" as below), it is easy to manage multiple units by location or number.
