Minnow 2.0 can be used for transport applications. Suppose for example you would like to transport some delicate or fragile cargo from one location to another. By attachment of a Minnow 2.0 logger one can record temperature and humidity conditions during the journey. At the destination you can then extract the logged data using a very simple PC application and see graphically or in raw data format the changes in environment over time. With its built in display, Minnow 2.0 can equally be used in-situ - for example in pharmaceutical storage.
Temperature and Humidity Measurement
Minnow 2.0 offers accurate and repeatable logging for temperature and relative humidity. Temperature is measured to an accuracy of /-0.17C over the range 5C to 60C and /-0.9C over the full range -25C to 80C. Relative humidity is measured to an accuracy of /-2.0% over 20% to 80% humidity range and /-5.0% over 0% to 100%. Both temperature and relative humidity are logged at a user configurable logging rate which can be set in a PC application program
NIST Traceable Calibration
Minnow 2.0 offers an optional NIST traceable single point calibration. Once calibrated Minnow 2.0 is accurate to /-0.07C within /-20C of the calibration point.
Minnow 2.0 has a clear LCD display with wide viewing angle, capable of showing temperature with a resolution of 0.01C and relative humidity with a resolution of 0.1%. Use of the display button on the logger will cycle through current, maximum, minimum and average logged values.
When you would like to ensure environmental conditions are kept within particular limits, one can also set operating ranges above or below which light indicators will be activated so that the user can become aware that the environment has gone outside allowed limits. The alarms are also visible on the display.
The Minnow 2.0 logger is equipped with the largest logging memory when compared with other portable logging devices currently available. Minnow 2.0 has provision for 65000 storage items each of which is a time-stamped recording of temperature and humidity.
Minnow 2.0 has been designed with special care to avoid water or dust from entering the logger. Both Minnow 2.0TD (temperature only version) and Minnow 2.0THD (temperature and humidity version) are rated IP-65.
External Sensor Probes
Minnow 2.0 can be used with external sensor probes. Probes can be of temperature only or temperature and humidity types. It is possible to mix and match T/TH sensors and loggers.
Simple to use PC Application
The Minnow 2.0 logger comes with a very easy to use PC application. The application is used for configuration of the logger, extraction of logger data, graphically viewing of logging data, spread sheet analysis of logging data and saving of logging data to file (typically in comma separated value CSV file format) for third party applications such as Microsoft Excel. The graphical user interface is completely intuitive in terms of configuring new devices and extracting logging data from a field device. When the user has multiple devices requiring the same setup then one can preload the application with a logger setup from a saved configuration file to help expedite the process and ensure all loggers get setup identically. The application does not require any driver installations to connect to your logging device. Just download the program from our home page, run it and then plug in you device. As simple as that! Currently the PC application is available for Windows XP, Vista, Windows 7, Windows 8 and Windows 10. It is also supported on Mac.
Minnow 2.0 runs from two CR2032 coin cell batteries available from supermarkets or online battery stores over the internet. The logger can log temperature and relative humidity for up to 2 years.

Frequently Asked Questions:
1. Why should I buy a Senonics Minnow 2.0 Logger?The Senonics Minnow 2.0 Logger has several selling points which set it apart from other loggers:
1) The logger is high accurary at affordable price.
2) The logger has a clear LCD display with 1 digital humidity and 2 digit temperature
3) The logger is water and dust resistant to IP-67
4) The logger has a small compact professional design
5) The logger has a robust construction
6) The logger comes with free intuitive software
2. What is the difference between Minnow 2.0TH and Minnow 2.0T?
The Minnow 2.0TH is a temperature and humidity logger. Minnow 2.0T only logs temperature. Otherwise the loggers have exactly the same features - for example accuracy, logging depth, LCD display, PC Application software etc.
3. What are the maximum logger durations for Minnow 2.0TH and Minnow 2.0T?This will depend on the logging interval:
1 second interval / 10 hours logging
10 seconds interval / 7 days logging
30 seconds interval / 22 days logging
1 minute interval / 45 days logging
10 minutes interval / 1.2 years logging
30 minutes interval / 3.7 years logging
1 hour interval / 7.5 years logging (or until battery is flat)
4. Do we need to by anything other than the Minnow logger?
No! Purchase of the logger includes the logger itself and two coin cell batteries. The software to configure the logger and extract data is free and installed from the Web. There is no special purpose programming pods or cables for our product. Everything is simple.
5. What is the preferred battery to use with my Minnow logger?
The Minnow 2.0 logger runs from two standard coin cell batteries. We recommend a CR2032 240mAH coin cell battery. There are different manufacturers but a good one is Panasonic CR-2032. You can find it easily on the web from different places such as www.digikey.com, www2.mouser.com and probably in your local supermarket. The key thing is to choose a CR2450 battery with high capacity since this will translate into a longer logger battery life.
6. What is the response time for the Minnow 2.0 logger for changes in temperature and humidity?
The Minnow 2.0 logger has high quality sensors and due to careful mechanical design is quite responsive. Usually we see a settling time of about 3 minutes for temperature and humidity changes.
7. How do I know if my logger is logging?
When logging the logger will flash the green status LED every 6 seconds. When the logger finishes logging or is turned off then the status LED is permanently off.
8. Can I synchronise multiple loggers?
Yes! If you use the "Start at Specified Time" mode in the configuration and use the same future time for different loggers then they will all start logging together. Try it.
9. What is the Real Time Logging Mode?
Your Senonics Minnow 2.0 logger can run in a mode where it is connected to the logger and the PC application instructs the logger to collect samples continuously at a desired rate. One can then see the samples collected as a table and graphically (live). This is a mode in addition to the regular logging modes and is a feature not supported by other loggers.
10. What version of Windows is supported?
The logger is a HID USB device which means it needs no special driver installed. It uses the driver included in Windows. Because of this the PC software can run on Windows XP, Vista, Windows 7, Windows 8 and Windows 10 in 32 or 64 bit and can be plugged into any USB port on the PC.
11. What options are there for post processing data from the logger?
The data extracted from the logger can be exported as a comma separated value (CSV) file. This is a standard text file format which can be readily processed by many third party programs such as Microsoft Excel, MatLab etc.
12. My PC does not seem to interpret the Senonics CSV format properly?
The CSV file format made by the Senonics PC application has been made to suite USA comma separated format. Usually this file can be opened directly within Excel.
On some PCs and in some countries this will not be interpreted correctly. Instead use the Senonics PC application to write the file with a .txt extension. Next open Excel and open the .txt file. You will be asked how to interpret the CSV file. Ensure that you select the "comma" delimiting. The file will then be interpreted correctly.
You can also now open the data directly using the open from Excel button.
13. How come I can not log more data after I have connected my logger previously in "scheduled start" mode?
When one has used scheduled start and the logger is then connected, logging will be immediately stopped. One may then retrieve the logged data. Unfortunately in this logging mode there is no way to restart the logging without reconfiguring the logger and therefore wiping the data. So you do not loose data but you can not add to the data.
In both logging on disconnection mode and logging on button press it is possible to restart logging when the logger is disconnected and new data is added to the old.
14. How long does it take to ship my logger once I have placed an order?
We endeavour to have all logger products in stock at all times. We ship with Fedex, DHL or UPS transport and the estimated time is 2 days world-wide.
15. Does Senonics make custom logger products?
Senonics is always keen to learn about customers needs and in some cases there could be a cooperative project which results in a custom logger product or setup. Contact us if you have suggestions to our products or some specific application in mind.
