Lascar Electronics' EasyLog brand has extended its reach into the Wi-Fi arena with the launch of its uniquely easy-to-use Wi-Fi temperature and humidity data logger, the EL-WiFi-TH. Designed to allow remote monitoring of the environment in which it is placed, the sensor seamlessly streams data collected back to the PC via a standard Wi-Fi network. Supplied with a free micro USB cable and software, the user connects the sensor to the host PC just once to choose a preferred Wi-Fi network and program the device. Once a Wi-Fi connection is established, users can name the logger, choose sampling and upload rates as well as alarms. Once programmed, the user can detach the unit and locate it anywhere within the range of the Wi-Fi network to record temperature and humidity. The sensor’s display allows users to view the strength of the Wi-Fi signal (assisting the user in optimum sensor placement), the minimum and maximum temp/RH readings and last log. Users can change the settings of any sensor on the system remotely using the supplied control software.
If Wi-Fi connection is lost during the logging process, the unit will automatically begin to store readings in its internal memory, with provision for up to half a million saved on-board. Once the Wi-Fi network is restored, the unit will upload all readings to the PC ensuring no data is lost. Multiple sensors can be set-up on any one system, depending on router type and Wi-Fi network use by other devices, with all devices viewable at the same time on the host PC. Summary data such as sensor name, battery life, alarm status and current connection status are viewable as well as a readout of the sensors’ digital display.
Irrespective of transmission rate chosen, in the event of an alarm being breached the sensor will immediately communicate that alarm situation to the host PC; this is indicated by an audible alert and visual indication within the control software. Users can view logged data in graph format at any time on the PC or export that information to Excel for further analysis if required.
