It is an ideal IoT platform to connect multiple devices. For the arduino part I used Pub-Sub Client as the MQTT library for arduino (Node-MCU). What makes MQTT faster than say sending HTTP requests with your IoT device is MQTT messages can be as small as 2 bytes, whereas HTTP requires headers which contains a lot of information that other devices might not care about. Arduino UNO not included. This is a very easy way to let the MQTT broker make the last message on a topic to be persistent. You can control your actuators remotely, connect your sensors easily, manage connected devices in real timeand analyze the acquired data over the cloud. Arduino Uno X 2: I used one Arduino Uno as I2C Master and the other as I2C Slave. Note that with MQTT, multiple publishers & subscribers can be using the same Broker/Topic. They also help us to monitor its perfo. So Arduino Mega is linked via W5500 LAN directly to my network router, the Openhab server with running MQTT Broker is also connected to the same network. A flow scheme of this way of transferring data from multiple sensors is shown in Figure 1. Texas Instruments offers a MSP430, MSP432x, TM4C, C2000, CC32xx and CC13xx LaunchPad. c #include <Arduino. I found this to be surprising as there must surely be many instances where one would want to upload data from Arduino to a MQTT broker in a mobile scenario where cellular network is the only option (in place of Ethernet). If you have more than one sensor value that you want to send to ThingSpeak, you can choose to publish multiple values to a channel feed. This project shows how to use MQTT communication protocol with the ESP32 to publish messages and subscribe to topics. I read the datasheet on the HC-SR04s and the Arduino Uno as well, and found that the ultrasonic sensor draws 15mA when active, and the Uno can supply a max of 40mA through each pin and a total of 200mA from all pins.
