Raspberry Pi Talking to ESP8266 over WiFi using MQTT. MQTT. MQTT is a machine-to-machine (M2M) data transfer protocol . MQTT was created with the goal of collecting data from many devices and then transporting that data to the IT infrastructure. It is lightweight, and therefore ideal for remote monitoring, especially in M2M connections that require a small code footprint or where network bandwidth is limited Here are the steps at a glance you need to follow in order to send sensor data from Arduino to Raspberry Pi. Initiate serial communication on your microcontroller setup (or Arduino). Physically connect Arduino and Raspberry Pi using a USB cable. Initiate I2C on your Raspberry Pi. Create a Python code base to receive sensor data coming from Arduino and a way to display the input. Run the code.

To send data to ThingSpeak, we need an unique API key, which we will use later in our python code to upload our CPU data to ThingSpeak Website. Click on API Keys button to get your unique API key for uploading your CPU data. Now copy your Write API Key. We will use this API key in our code.

The big advantage is that the built-in wifi adapters (for example in the Raspberry Pi or in the ESP8266) are used for the internet connection. More accessories and complicated wiring is not necessary! This makes it possible to send the data via the local network or the Internet. In detail, the transfer consists of three different components: Publisher: Sends messages. Broker: Forwards messages. Data acquisition is important to further do analysis. ThingSpeak allows us to send the data and display it in the graph. For the student, the best thing is, it also offer a free account for you to try. So in this tutorial, I will share with you how to send sensor's data to ThingSpeak using Raspberry Pi. You may need to refer the following.

For this project, we wanted to transfer data from sources such as a PC or a Raspberry Pi to the ESP8266 using UDP protocol. The data can be information or something more substantial, such as commands to control the ESP8266's GPIOs. We accumulated a few code examples from various sources and came up with a simple code that sends a ASCII text to the ESP8266 from a PC and then an. To establish serial communication between Raspberry Pi and Arduino, simply connect them with a suitable USB cable. In our case, we use a Raspberry Pi 3B+ and an Arduino UNO. So we need a USBA Male to USB B Male cable. It is also possible to create serial communication by using the Rx/Tx pins of both components I need to send temperature readings that have been stored in my raspberry pi as an xls file, to my website. after that on the server side, the other team is resposible to parse that data using PHP or whatever. my responsibility is to make a python script that will send this data to the server
