Project Description:
*******
So far I have used LoRa Transceiver modules with Arduino, Nodemcu ESP8266, and STM32 controller boards. Today, for the first time I am going to use these Long Range LoRa SX1278 Transceiver modules with ESP32 controller boards.
As you know ESP32 is much more powerful than the ESP8266 and Arduino. It is even faster than the Raspberry Pi Pico and STM32. And as you might know, ESP32 has onboard WiFi and Bluetooth and this is what makes the ESP32 much more popular than all the other controller boards.
So, in today’s episode, you will learn how to make a Long range wireless Home automation system using ESP32 WiFi + Bluetooth modules, LoRa SX1278 Transceiver modules, 12V SPDT type relays, 110/220Vac Bulbs, and some switches.
In this project, I am using two ESP32 modules, one as the sender and the other one as the receiver. I have connected everything as per the circuit diagrams which I will explain in a minute.
You might have noticed, that I am using two different versions of the ESP32 WiFi + Bluetooth modules. I could use the similar ESP32 modules, but the reason I am using different versions is that to explain it doesn’t matter which one of these you use; the code is going to work just fine.
If you want to use 110/220Vac supply, you must not forget to use protective gloves, because 110/220Vac can prove fatal. So, as far as possible you must ensure the presence of a friend or any companion while working on such projects. When the AC supply is ON, do not touch the relay contacts. Now, let’s go ahead and kick off our practical demonstration.
