Send Sensor's Data to ThingSpeak Using Raspberry Pi

Introduction

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 tutorial to get familiar with other IoT platforms.
