Paxcounter LoRa V2.1_1.6.1 ESP32 433/868/915MHZ 0.96 Inch OLED SD Card

LILYGO® TTGO & Paxcounter Paxcounter is an ESP32 MCU based device for metering paenger 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 adrees. 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 adrees 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/, or transmitted to a local host using serial (SPI) interface.

LoRa V2.1_1.61 compared to LoRa V1.0 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 can enhance signal transmiion.
