The 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*. During configuration, the sensor 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 EL-WiFi sensors have an impressive range this can be increased by using WiFi
The EL-WiFi-TC is a low powered battery device. When configured using typical transmission periods (e.g. once
every hour) the sensor will operate for up to one year (at room temperature). The battery can then be recharged via a
PC or USB +5V wall adapter using the USB lead provided or can be permanently powered by the USB wall adapter.
The software installed on the PC will allow set-up, data logging and data review. Set-up features will include sensor
name, °C/°F, sample rate, and high/low alarms. Once configured, historic data can be viewed via the graphing tool or
exported into Excel. This software is available to download for free from www.congnghethongminh.vn.
The sensor is a freestanding unit, however, it can be attached to a wall or vertical surface using the bracket and screws/
sticky pad provided.
It is supplied with a thermocouple probe with an attachment so that it can be securely fixed to flat surfaces. It is perfect
for a wide range of temperature monitoring situations e.g. manufacturing processes, cold/hot storage and laboratory
conditions. The probe is removable so alternatives can also be used to meet specific requirements providing they
operate within the same temperature range. The EL-WiFi-TC supports J, K, N and T thermocouple probes.
