AT-100 microCache Logger

The new Apogee AT-100 microCache (µCache) Bluetooth Micro Logger connects directly to several Apogee sensors. Features live meter mode, stand-alone datalogging, and graphing using our free Apogee Connect App for iOS and Android.

The AT-100 is a ruggedized, battery-powered, Bluetooth® Low Energy, single-sensor datalogging device that currently interfaces with Apogee’s quantum sensor line, with other Apogee sensors coming soon. When used as a standalone field-logging device, the unit features enough memory to store 9 months of one minute data using the internal battery. Data can be viewed on your mobile device using our free Apogee Connect App software for iOS and Android devices, with a Wifi gateway coming soon. Apogee Connect features live meter mode, real-time graphing, and the ability to send datasets to your computer via email.
