It is t e policy of OMEGA Engineering, Inc. to comply wit all worldwide safety and EMC/EMI
regulations t at apply. OMEGA is constantly pursuing certification of its products to t e European New
Approac Directives. OMEGA will add t e CE mark to every appropriate device upon certification.
T e information contained in t is document is believed to be correct, but OMEGA accepts no liability for any
errors it contains, and reserves t e rig t to alter specifications wit out notice.
WARNING: T ese products are not designed for use in, and s ould not be used for, uman applications.

The OM-EL-WiFi-TH sensor measures the temperature and humidity of the environment in which it 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 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 (max 60 days at 10 second
sample interval). The range of the sensor can be increased by using WiFi extenders.
This OM-EL-WiFi-TH 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 battery is safely charged when the unit is operating between 0 to +40°C (+32 to +104°F). It is protected against charging outside this
temperature range. Sensor readings may be inaccurate during battery charging.
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 for free from www.omega.com.

The sensor clips into the bracket.
All OM--EL-WiFi-TH 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.

LCD SCREEN SHOTS
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.
