Tips For Taking Accurate Measurements

When managing a burn site, knowing environmental conditions are within prescription is important for compliance and to ensure a fire doesn’t get out of control.  Gathering sufficient weather data from site visits to make a decision on when to burn can be challenging.  In addition to the full wind and weather readings from a Kestrel weather meter, the new Kestrel DROP data loggers can be left on site recording a history of conditions and trends which can then be viewed on a mobile device and shared via email.

Small, Accurate, Rugged and Waterproof

Each Kestrel Fire Weather DROP measures just 1 x 1.8 x 2.4 inches (24 x 46 mm x 60 mm) and weighs just 1.2 ounces (34 grams).  DROP loggers meet military and international standards for water, dust and shock resistance (IP-67 and MIL-STD-810G) and are conveniently equipped with a sturdy D-ring for hanging wherever needed.

Log, View and Share on the Kestrel LiNK App

Kestrel LiNK is the free app that powers the Fire Weather DROP data logger. With Kestrel LiNK on your smart phone or tablet, you can view real-time readings from any DROP logger within wireless range (up to 100’ or more line of sight) via Bluetooth® low energy. Min/Max/Average readings are clearly displayed and the data log is viewable as a scrolling graph with detailed data for each logged point. The Kestrel LiNK app also allows adjustment of the logging interval and other settings as well as real-time threshold alerts. Readings can be updated as frequently as every 2 seconds and logging time and date are automatically updated whenever connected to your smart device.  You can also send and share real-time and logged environmental data via email, Facebook or Twitter

Requirements:

  • iOS 6 installed iPhone 4s, iPad 3rd generation or iPod Touch 5th generation – or any later iOS or hardware configuration. Will not work on iPhone 4, 3GS or 3G or any earlier iPad or iPod generation.
  • Android 4.3 and higher. Works with most Android devices with Bluetooth Smart®, including Samsung Galaxy, Nexus 4, Motorola Droid and other recent generation phones and tablets.

Airflow of 2.2 mph|1 m/s or greater provides fastest response and reduction of insolation effect. For greatest accuracy, avoid direct sunlight on the temperature sensor and prolonged sunlight exposure to the unit in low airflow conditions. Calibration drift is negligible for the life of the product. For further details, see Battery Operational Temperature Limits.
Relative Humidity 2%RH 0.1 %RH 10 to 90% 25°C noncondensing To achieve stated accuracy, unit must be permitted to equilibrate to external temperature when exposed to large, rapid temperature changes and be kept out of direct sunlight. Calibration drift is typically less than ±0.25% per year.

Response Time & Display Update Display updates every 1 second. After exposure to large environmental changes, all sensors require an equilibration period to reach stated accuracy. Measurements employing RH may require longer periods particularly after prolonged exposure to very high or very low humidity. WBGT requires about 8 minutes to reach 95% accuracy and about 15 minutes to reach 99% accuracy after exposure to large environmental changes.
Data Storage Logged history stored for every measured value. Auto-store interval settable from 2 seconds to 12 hours*, overwrite on or off. D1: >13,000 data points, D2: >7,000 data points, D3: >6,000 data points.

Product Questions

The Stats page shows the data that is currently stored in the logger on the DROP. Currently you need to disconnect and reconnect to acquire more data, so the Refresh is useful only during an active download. You can hit the Refresh button to populate more Stats as they are in the process of being downloaded to the application.

Set the logging rate to the max, 12 hours. You could set the data refresh rate to its max, 1 minute, but that will only have an effect when connected to the DROP. Also if you connect to the DROP in colder weather, this will affect battery life more than in warmer temperatures. If possible, warm up the DROP before doing a data upload to Kestrel LiNK to help with battery life.

This is really just personal preference. If the DROP name is related to its location or purpose, then obviously changing the name would be helpful each time.

Yes. Once you make the settings to the DROP (custom name, logging rate, data refresh rate), those settings stay with the DROP itself. This means that all anyone else would have to do is download the Kestrel LiNK(Formerly Kestrel Connect) app from the iTunes App store and connect to the DROP to access.

To read the data that has been logging on the DROPs, all you have to do is simply connect to the DROP with your iOS or Android device and the data log will be downloaded. You can tell it’s downloading by looking at the DROP’s name near the top of the screen, as you’ll see a spinning graphic and a percentage that changes over time. Once it has reached 100%, you’ll have to navigate to the Stats screen using the menu at the bottom of the app. There you’ll find an Export Data button at the top which you can use to email the data log to yourself and then print it out.

This is dependent on a setting for the DROP in the Manage Data Log section. If you go to Manage->Manage Data Log, you will notice a Wrap Log toggle button. If the Wrap Log toggle button is slid to the right (indicates ON), then the oldest logged data will be overwritten when the data logger is full. If the slide is to the left (indicates OFF), then no more data will be collected when the data logger becomes full.
