Overview
The Inventory Master LoRa WAN parking sensors use an anisotropic magnet resistive sensor to monitor changes in the magnetic field on the parking space and check whether the parking space is occupied or free. It is connected to the gateway or network coordinator by various transmission methods such as LORAWAN and NB-IOT, and then transmitted to the server through 4G or Ethernet.
