LoRa32 V2.1_1.6

• Paxcounter is an ESP32 MCU-based program 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 Bluetooth 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.
• 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.

• Disaster.radio is an off-grid, solar-powered, long-range mesh network built on free, open source software and affordable hardware.
• Designed to be open, distributed, and decentralized, disaster.radio is currently in the prototype/development phase.
