A variety of miniature data loggers is proposed to collect physical and environmental information on free ranging animals over long time periods. Recorded parameters may include external or body temperature, diving depth, flight altitude, light level, and/or 3D accelerations.

Extremely low power consumption brings outstanding life time/small and lightweight characteristics.
Various kinds of casing are available for external or implantable use.

The loggers must be returned to ATESYS to retrieve the recorded data.
