The OM-EL-WiFi-TP sensor measures the temperature of the environment in which the probe is situated. Data is transmitted wirelessly
via a WiFi network to a PC and viewed using a free software package. During conguration 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 (max 120 days at 10 second
sample interval). The range of the sensor can be increased by using WiFi extenders.
The probe can be used in a wide range of temperature situations e.g. manufacturing processes, cold storage and hot storage.
This OM-EL-WiFi-TP is a low powered battery device. When congured using typical sampling periods (e.g. once every 60 seconds) the
sensor will operate for over one year. The battery can then be recharged via a PC or USB +5V wall adapter using the USB lead provided.
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 to Excel. This software will be
available for free from www.omega.com.

EXAMPLE OF UNIT WHILST PHYSICALLY CONNECTED TO PC DURING SET-UP
HARDWARE
• Battery: Rechargeable via USB connection
• Microcontroller: ARM MCU
• 1x micro USB Type B (bottom of unit) for connection of unit to PC via USB cable supplied.
• Removable probe: 50cm, 304 stainless steel end cap, high temperature exible cable with tight bend radius
This sensor stands alone by itself on a horizontal surface and comes with a wall bracket that can be screwed onto a wall or at surface.
The sensor clips into the bracket.
The sensor is supplied with a thermister probe with an attachment so that the probe can be securely xed to at surfaces.
The probe is removable so alternative probes can also be used to meet specic requirements providing they operate within the same
temperature range.
All OM-EL-WiFi-TP sensors are thoroughly tested pre-release but the sensor may experience compatibility issues with certain WiFi networks.
In this instance we recommend the use of network accessories available on the Omega website.

ADDITIONAL FUNCTIONALITY
When the user cycles through to the Recieved Signal Strength Indicator (RSSI) screen the unit automatically transmits a dummy message
every 2 seconds to enable an RSSI reading to be displayed. If there is any outstanding data waiting to be transmitted, this data will be
sent at the same time but if not it’ll just send the dummy message and the next data package will be sent as per the unit conguration.
When on Max or Min screen, holding the button for 3 seconds will clear the stored values.
The sensor can be restarted by holding the button for 10 seconds until the screen blanks and LOW is shown ashing in the top right hand
corner of the display. The sensor will retain all settings but will lose any data that has not been transferred to the PC. The sensor can be
reset to factory state by holding the button for 20 seconds but this will delete all settings and stored data.
Note: neither the restart or the reset will delete data already transferred to your PC.
