|
||||
|
||||
Intention of this project is to do this without intrusion in privacy: You don't need to track people owned devices, if you just want to count them. Therefore, Paxcounter does not persistenly store MAC adresses and does no kind of fingerprinting the scanned devices.
|
||||
|
||||
Bonus of this project is that metered data is transferred via a LoRaWAN network, not via usual GSM/LTE or Wifi uplink.
|
||||
Metered counts are transferred to a server via a LoRaWAN network, and/or a local SPI cable interface.
|
||||
|
||||
You can build this project battery powered and reach a full day uptime with a single 18650 Li-Ion cell.
