The Minnow 1.0 is the most compact logger offering from Senonics measuring.


The Minnow 1.0 is commonly used in transport applications including but not limited to transport of:

  • SENSITIVE/FRAGILE ITEMS
  • FOOD
  • ANIMAL/LIVESTOCK
  • PLANTS
  • CHEMICAL
  • MEDICINES OR ORGANS

 

 

 

Suppose for example you would like to transport some delicate or fragile cargo from one location to another. By attachment of a Minnow 1.0 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.


Temperature and Humidity Measurement 

The Minnow 1.0 offers accurate and repeatable logging for temperature and relative humidity. Temperature is measured to an accuracy of /--0.3C over the range 5C to 60C and /--2.0C over the full range --30C to 80C. Relative humidity is measured to an accuracy of /--2.0% over 20% to 80% humidity range and /--4.0% 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 

The Minnow 1.0 is available with an optional NIST traceable single point calibration at any temperature between 15C and 35C or 0C. Once calibrated the Minnow 1.0 is accurate to /-- 0.1C within /-- 20C of the calibration point.  

Alarms 

When you would like to guarantee that items are transported within particular environmental limits then one can also set operating ranges above or below which light indicators will be activated so that the user can become aware that the desired transportation conditions have been exceeded.  

         

Logging Storage 

The Minnow logger is equipped with the largest logging memory when compared with comparable portable logging devices currently available. The Minnow logger has provision for an impressive 65520 storage items each of which is a time-stamped recording of temperature and humidity. 

Device ID & Data Security 

The Minnow1.0 logger enables each device to have a 16 character name. This can be helpful when the user has multiple logging devices and one would like to distinguish between them for example based on location. Logging data may also be password protected so that data may only be retrieved from the device by supplying a user supplied password. 

Long Battery Life 

The Minnow 1.0 logger runs from a single CR2450 coin cell better available from supermarkets or online battery stores over the internet. The logger can log temperature and relative humidity for up to 4 years. 

Simple to use PC Application 

The Minnow 1.0 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. 

  

Look and Feel 

The Minnow 1.0 logger design is compact, elegant and simple. Care has been taken to ensure the design is stylish and only makes available buttons, indicators and connectors which are intuitive and uncomplicated. The Minnow 1.0 has a handy key ring attachment for easy transportation. 

Moisture Resistance 

Every logger circuit board assembly is epoxy coated to protect the device from wet and condensing enviroments.

NIST Calibration 

The Minnow 1.0 is available with an optional NIST traceable single point calibration at any temperature between
15C and 35C or 0C. Once calibrated the Minnow is accurate to /-- 0.1C within /-- 20C of the calibration point.
Documentation will be provided that traces the calibration back to a NIST tested reference thermostat.

Senonics designs and manufactures it's own thermoelectric reference chambers that are stable to /-- 0.03C
over four hour time period. Every calibrated logger is tested at the desired temperature for four hours to
determine its offset from the reference temperature. Once the difference is determined an offset is applied
to the logger and then the logger is retested to verify it's performance. All test results are documented
in the NIST report.  

Senonics guarantees the accuracy of the Minnow for one year from the date of calibration. 

 

Frequently Asked Questions: 


1. Why should I buy a Senonics Minnow 1.0 Logger?

The Senonics Minnow 1.0 has five selling points which sets it apart from other loggers:
   1) The logger is likely the most compact temperature humidity logger around (35mm x 60mm x 15mm)
   2) The logger is low cost (only US$79 per unit)
   3) The logger has free software for configuration and data extraction
   4) The logger requires no special programming pods - just a standard USB cable
   5) The logger has a logging depth which surpasses rival loggers - 65520 sample depth (temp, humidity pair) 

 

2. Do we need to by anything other than the Minnow 1.0 logger?

No! Purchase of the logger includes the logger itself, a USB cable and a coin cell battery. 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.
 

3. What is the preferred battery to use with my Minnow 1.0 logger?

We recommend a CR2450 620mAH Coin cell battery. There are different manufacturers but a good one is Panasonic CR-2450/G1AN. You can find it easily on the web from different places such as www.digikey.com, www2.mouser.comand 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.
 

4. What is the response time for the Minnow 1.0 logger for changes in temperature and humidity?

The Minnow 1.0 has high quality sensors and due to careful mechanical design is quite responsive. Usually we see a settling time of about 4 minutes for temperature and humidity changes.
 

5. 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.
 

6. 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.
 

7. What is the password protection feature?

Your Minnow 1.0 has an optional password protection. If you enable this then the user must enter a password before you can see the data from the PC application. This is meant for applications where you want a restriction that only certain users to get access to the logged data.
 

8. What is the Real Time Logging Mode?

Your Senonics Minnow 1.0 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.
 

9. 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.

10. 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.
 

11. 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.
 

12. 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.
