The OM-EL-WiFi-T-PLUS sensor measures the temperature of the environment in which it is situated. This high accuracy version is accurate
to ±0.1˚C. Data is streamed wirelessly over any WiFi network and can be viewed on a PC using our free software package or on the
OM-EL-WiFi-Cloud*. During conguration, the sensor will search for an existing wireless network while 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 120 days at 10 second sample interval). Although the
OM-EL-WiFi sensors have an impressive range, this can be increased by using WiFi extenders.

PHYSICAL DIMENSIONS
All dimensions in millimetres (inches)
The OM-EL-WiFi-T-PLUS is a low powered battery device. When congured using typical transmission periods (e.g. once every 5 minutes) the
sensor will operate for over 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 congured, historic data can be viewed via the graphing tool or exported into Excel. This software is
available to download for free from www.omega.com.
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.
