Paxcounter is an ESP32 MCU based device for metering passenger flows in realtime. It counts how many mobile devices are around. This gives an estimation how many people are around.
-
Paxcounter detects Wifi and Blue/tooth signals in the air, focusing on mobile devices by evaluating their MAC adresses.
-
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.
-
Data can either be be stored on a local SD-card, transferred to cloud using LoRa WAN network or MQTT over TCP/IP, or transmitted to a local host using serial (SPI) interface.
