The TGRF-4600 is a battery powered, radio data logger with a temperature
and relative humidity probe..
The probe supplied with the data logger can be inserted into hard to reach
areas, such as air conditioning vents and wall cavities to record temperature
and relative humidity.
The logger is used as part of a Tinytag Connect system that requires a
receiver and the Connect version of the Tinytag Explorer software.
After the installation of the software and the configuration of the receiver, the
logger is turned on and will establish itself as part of the mesh network the
system creates.
The typical range of the logger on a clear line of sight is 200m.
The logger is then set to record at a user-defined logging interval, anything
from once every 2 minutes to once every 10 days.
The data recorded by the logger is stored on the computer running the system
by a Windows service (called the radio gateway) and this is then viewed
across a LAN or the Internet through the Tinytag Explorer Connect software.
If a logger cannot communicate with the mesh network for any reason, it will
record locally until communications are restored.
The logger can be programmed with alarms. Warning e-mails can be sent
when the limits entered are exceeded.
Data recorded by the system can be viewed as a graph or as a table of
readings. There are also summary views containing information about the
recording run and a daily min/max view.
Data from multiple devices recording at the same time can be combined into a
single graph using Tinytag Explorer Connect.
Data can be exported from the software as a graph image, for use in report
writing, or as a data table, for further analysis in third-party spreadsheet
programs.
How the Logger Works
Logging Interval
2 minutes to 10 days
Off-line storage Capacity*
2 weeks typical, at a 10 minute logging
interval
Data loggers can be set to record in intervals of once every 2 minutes or
greater (by default the logging interval is set to once every 10 minutes).
When radio communications are good, data is transmitted immediately and
stored by the gateway service.
When communications with the gateway service are interrupted, by a power
failure to the computer running the gateway service or an obstacle causing a
blockage in radio communications, data loggers will record locally and then
transmit data when communications are restored.
The off-line storage capacity of a data logger, for any given logging interval, is
stated at the bottom of the configuration page in the Tinytag Explorer Connect
software when the logger is programmed (this will be a minimum of 2 weeks
when set to record at the default 10 minute logging interval).
*The local storage capacity of the logger is an indication of how much data the
unit can record when it is unable to communicate with a receiver.
Alarms
2 fully programmable, latching alarms
Alarm Delay
1 second to 10 days
Loggers can be programmed with alarm limits that will cause warnings to be
shown in Tinytag Explorer Connect and to make the unit's LED flash red.
Two alarm limits can be programmed per channel, allowing upper and lower
boundaries to be set.
Delays can be set on the alarms so that routine tasks, such as restocking a
fridge of freezer, can be performed without causing alarms to be activated.
E-mail warnings can be sent when alarm limits are breached, and these in turn
can be used to send SMS messages using third party messaging services.

The logger uses FSK modulation, with +/-32 kHz deviation.
These frequencies will easily penetrate most internal walls, but the range may
be reduced to between 30% and 80% (however it will sometimes be
increased, maybe up to double the nominal range, due to reflections off walls
and roofs etc.).
Although the radio waves cannot penetrate a metal wall (fridges or corrugated
iron sheds etc.) the signal will often still get through gaps around door seals,
windows and air vents etc.
These frequencies are very slightly absorbed by water. Wet walls are not a
problem, but the signal will not get through a room filled with shelves full of
fruit or bottled water, for example.
The advantage of the mesh network is that loggers in locations with shorter
ranges will often be able to relay data though other loggers that are able to
transmit further.
