The number of connected devices continues to increase day-by-day. With the availability of low-cost hardware like sensors, microcontrollers, and single board computers, we’ve seen a large increase in the smart devices being deployed around us. Whether it is a dishwasher or a car, we can find sensors everywhere, and these IoT devices are getting smarter because of cloud service providers like IBM.
This tutorial is a step-by-step guide that helps you create a simple IoT system that can make use of readily available components like cloud services and a smartphone. We will be using an Android smartphone and its accelerometer sensor which will be acting as a sensor node. We will get and send that sensor data over the MQTT communication protocol to a Node-RED dashboard for analysis and visualization.
