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 addresses.
-
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 persistently store MAC addresses and does no kind of fingerprinting of 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.
