In the next slide, we will give you a brief introduction about them.

Components Requirements to create Arduino Interface LM35 MQTT Using UART -

ARDUINO UNO

Arduino/Genuino Uno is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button.

ETHERNET SHIELD

The Arduino Ethernet Shield 2 allows an Arduino Board to connect to the Internet. It is based on the Wiznet W5500 Ethernet chip. The Wiznet W5500 provides a network (IP) stack capable of both TCP and UDP.

HC-05(2No)

HC-05 module is an easy to use Bluetooth SPP (Serial Port Protocol) module, designed for transparent wireless serial connection setup.

LM-35 (Temp Sensor)

The LM35 series are precision integrated-circuit temperature devices with an output voltage linearly-proportional to the Centigrade temperature.

Here we are implementing a Master-Slave Communication between two Arduino Uno Board with HC-05(Bluetooth) and Sending orreceiving data to and from an MQTT Client.

Here we are using Ethernet Shield to Communicate with MQTT Broker Adafruit and interface out Board with it. Here we are also using two additional libraries of Adafruit (Link is given below).
