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.
