The Lascar EL-WIFI-TC sensor measures the temperature of the environment in which the probe is situated. The accuracy of the K type probe supplied is +/-1.5 °C. Data is streamed wirelessly over any WiFi network and can be viewed on a PC using our free software package or on the EasyLog Cloud (due to be released late 2013). During configuration, the ELWIFITC will search for an existing wireless network whilst physically connected to the PC. It can then be placed anywhere within range of the network. If the sensor temporarily loses connectivity with the network, it will log readings until it is able to communicate again with the PC application or cloud service (max 30 days at 10 second sample interval). Logged data is retained if the battery goes flat. Although The Lascar EL-WiFi sensors have an impressive range this can be increased by using WiFi extenders.
