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.
The LoRa communication capacity of the board opens up a web of possibilities and as a demonstration of how the board works, for today’s tutorial, we are going to build a LoRa Sensor Monitor with a webserver.
The idea behind the project is simple and not so different from the “Introduction to LoRa communication” project we built recently. It comprises two parts; a Transmitter and a Receiver. The transmitter comprises of a TTGO LoRa32 development board along with a BME280 sensor which is used to obtain temperature and humidity parameters from the environment. The data obtained are sent using the LoRa Communication features of the TTGO LoRa32, to the receiver which receives the data and displays it on a webpage via a webserver hosted on the board. By visiting the IP address of the server on any device on the same network as the receiver’s LoRa32 board, users will be able to see the data displayed on a webpage.
At the end of today’s project, you would know how to use both the WiFi and LoRa features of the TTGO LoRa32 board.
