IoT Garden – Data Visualization

IoT Garden – Data Visualization

Here comes the last part of “IoT Garden” series where I’ll demonstrate how to quickly visualize data gathered from various sensors. Now for my project I wanted to visualize temperature, humidity and soil moisture collected from my garden. In last post we saw way to bring collected data upto AWS IoT over MQTT Topic called “garden/data”. In this post, I’ll walk you through how different AWS services will help us visualize this data! Amazon CloudWatch Custom Metric In order to…

IoT Garden – Data processing

IoT Garden – Data processing

In my last post we talked about making sensor data usable by making it available over network for anyone else to consume. In this post, lets take this concept further and see how do we connect this data with cloud IoT providers. Main requirement here is to be able to plot sensor data over time, see how it changes with environment changing around it and then finally use gathered data to predict future values.¬†For now lets only focus on part…

IoT Garden – Data Acquisition

IoT Garden – Data Acquisition

In this post, we’ll concentrate on getting data from sensors and making it available for anyone else to consume. In my case, I used sensors with Node MCU board from Amica. Node MCU Node MCU is a low cost micro-controller chip with built in Wifi. This unit basically runs on ESP8266 chip which has built in Wifi. Total storage available on chip is 4 MB so your compiled code can be as large as 4 MB. This simple board has…
