TTGO ESP32 LoRa32 V2.1 1.6.1 433/868/915MHZ OLED 0.96Inch SD Card BT WIFI Module. Product Description TTGO ESP32-Paxcounter LoRa32 V2.1 1.6.1 Version 433/868/915MHZ LoRa ESP-32 OLED 0.96 Inch SD Card BT WIFI Module
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 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.
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 LoRaWAN network or MQTT over TCP/IP, or transmitted to a local host using serial (SPI) interface.
At the TTGO LoRa V2.1_1.61 ,we add the SMA and TP4054 to the board,which make it can do more things.In terms of the power switch, we have changed the switching interaction mode. The added SMA antenna can enhance signal transmission.
