FreeRTOS_IoT_Arduino-and-NodeMCU

Implementation of FreeRTOS with IOT, using Arduino + transmitter and Nodemcu + Receiver with Wifi connection to publish MQTT message

Using 2 Separate Microcontrollers

1. Arduino Micro (Uno,mini,etc compatible) With 433Mhz Transmitter Module and a Gas sensor as data source

   Read analog voltage of pin A0 in arduino and transmit data using transmitter. Coordinated by FreeRTOS.
   
   

2. NodeMCU / ESP8266 With 433Mhz Receiver

   Receive data from transmitter, and react based on incoming data. In this case we publish MQTT message.
