NETVOX Wireless Asset Sensor R313D, The device is a simple positioning function (which can detect the position status of the device), periodically reports RSSI and SNR information to the gateway for processing and can locate the position status of the device according to the reported RSSI and SNR information, and adopts SX1276 wireless communication module

Example Applications

The device is universal an can be used for many applications. Ideally suited for a wide range of applications such as monitor the fixed asset location and avoid the asset being moved out from location. For example:

Schools / Classroom / Reading room / Laboratory / Offices PC room equipment
