Moreover, it seemed to me practically, the data wirelessly via the enclosed USB - collect radio stick.
But the seemingly good concept has unfortunately but a few flaws ...
Benefits:
=========
- Large memory:
Memory for 50000 measurements enabling it to sign many sensors over a long period.
- Accurate Sensors:
In the apparatus as well as the wireless sensors I have found a maximum deviation of 0.5 ° C and 4% RH.
Which is great for devices in this price range. Previously, there was the opportunity to sensors
calibrate. That's when IT + no longer necessary (but also no longer possible).
- Fast measurements:
Unlike other reviews I did not win the impression that the measurements were sluggish.
In my opinion, the measured values are noticeably faster than its predecessor.
- The dew point is logged with:
Important and useful if you want to monitor the ventilation behavior in all seasons.
- Alarm with external interface:
In addition to the acoustic alarm, an external alarm device to be connected via a 3.5mm jack.
- CSV file:
The logged readings can be saved as a CSV file and open so directly in Excel and to chart.
You just have to make sure that is the failure of a sensor "---" in the table.
This "---" you have to first replace with "0", then it works without any problems with Excel
- Reading via radio:
One no longer needs to connect via cable to your PC to read the records the device.
The range of the radio link with the supplied USB - stick is approximately 6-10m in the house through walls.
- Wireless sensors IT + with 868 MHz:
Easy to install and can be named.
Even following a battery replacement at the base station or the radio sensor, the connection remains active!
- Beautiful keyboard, simple operation:
A large number smoother buttons and a clear, successful display, make on - site operation
and the teach-in new sensors to a pleasant breeze.
Disadvantages:
==========
- Radio transmission can not be initiated by the PC:
That which initially presents itself as a great advantage, namely the wireless readout of the unit by radio, has a great hook.
Although one does not need a cable, but the unit must always install the "USB" - press button.
so the logger must be always available to start a reading.
Time at the office "so just" see what values were measured in the bedroom, thereby making it impossible.
The connection is quite slow. Can read all 50000 data for more than 1 hour take !.
- Range of 868 MHz wireless sensors deficient:
Unlike the old 433 MHz - 868 MHz wireless sensors, the new sensors have only a very modest range.
Walking in the open field about 25m, but in the house, especially if metal in the area (kitchen, hobby room, etc.),
If the range of the radio sensors in places under 5m!
For example, I easily with the old 433 MHz sensors can measure through a closed garage door.
With the new 868Mhz sensors that is totally impossible.
The indication '100m range "is a joke.
- Primitive Software:
The "KlimaLogg PRO" software V1.2.0, which can be downloaded from the homepage TFA is quite primitive.
At best suited to export a record as CSV and to give the sensors name.
It is particularly annoying that we basically never know, if you read the data straight from the device or deletes,
or if you only work on the PC.
TIP: Always look in the lower STATUS BAR !!
Here is to be hoped that in the future a little more comfortable TFA software - versions provides.
Conclusion:
======
Who wants to have an easy to use and quite accurate climate logger at an affordable price,
can access. But not too many "great" of the IT + - Features promise these are so far only rudimentary.
However, devices (30.3015) but significantly better served - Who needs greater distances even under unfavorable circumstances, which is the older, somewhat expensive 433 MHz!
