This RFID logger is designed for fitting over the mouth of a burrow. It will record the time and date of every visit to the burrow on an SD card, differentiating between entries and exits.

The RFID tag reader is fully integrated, and is only activated when an animal passes through the mouth of the burrow, so each logger can run for months from 5x AA batteries.

These burrow monitors will be available in various sizes, but for now, the internal diameter is 85mm. Please contact us for other sizes.
