Small, Accurate, Rugged and Waterproof

Each 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 Connect App

Kestrel Connect is the free app that powers the DROP loggers. With Kestrel Connect 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 or 30 meters) via Bluetooth Low Energy.  Each phone or tablet can connect to up to 8 DROP loggers at the same time and store data logs from many more. 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 Connect 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

DROP Customer Feedback:

The Kestrel DROP D2 and D3 are absolutely the best kept secret in the cigar industry! In the high tech world we live in, I am now able to keep a vigilant eye over my investment by remotely monitoring the environmentals of my humidor via a simple app on my iPhone. Having the ability to set alerts when humidity and temperature drop or go above ideal conditions is invaluable.  This is a MUST HAVE accessory for anyone with a humidor!
