ESP32 LoRa Sensor Monitoring with Web Server (Long Range Communication)

ESP32 LoRa Sensor Monitoring with Web Server (Long Range Communication)

I’m a big fan of the ESP32 boards because of the number of communication options they managed to squeeze on the board, but I became more impressed recently when I came across the TTGO LoRa32 development boards which adds LoRa to the onboard communication features of the ESP32.

Introduction to LoRa – Send data between two Arduino using LoRa

Introduction to LoRa – Send data between two Arduino using LoRa

Selecting the right communication protocol is an important part of any IoT project as not being able to communicate with the server/device cloud quickly takes away the “I” in IoT and could lead to the ultimate failure of the project.

Video Streaming Server on ESP32-CAM

Video Streaming Server on ESP32-CAM

A while back, I noticed an ESP32 based Camera board called the ESP32-CAM on LCSC.com, and planned on getting one to play with but didn’t get the chance until recently when I saw a tutorial by Rui Santos based on the board.
