How it works

This is the ultimate set-and-forget solution. No need to relocate the logger or connect it to a computer for data reading. The logger remains stationary, transmitting data wirelessly.


Plug in the gateway

Connect the gateway through Ethernet or Wi-Fi to collect data from loggers and transmit it to a server. Each gateway can handle data from 20 monitor tiles within a 100-meter range in ideal conditions.


Place the logger

The compact logger, 6.5 x 4cm x 1cm , fits anywhere like fridges or freezers. Once placed, it sends data to the base station without moving, using a replaceable 12-month battery.
