Paxcounter is an ESP32 MCU-based program for metering passenger flows in real-time. It counts how many mobile devices are around. This gives an estimation of how many people are around.

Paxcounter detects Wifi and Bluetooth signals in the air, focusing on mobile devices by evaluating their MAC addresses.
This project intends to do this without intrusion in privacy: You don't need to track people-owned devices if you just want to count them.

Paxcounter does not persistently store MAC addresses and does no kind of fingerprinting of the scanned devices.
Data can either be stored on a local SD card, transferred to the cloud using LoRa WAN network or MQTT over TCP/IP, or transmitted to a local host using a serial (SPI) interface.
