Use a DROP Anywhere livestock are housed- 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.

DROPs Are Powered by the Kestrel LiNK App

Kestrel LiNK is the free app that powers the DROP loggers. 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.  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 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.
