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…

IoT Garden – The Architecture

IoT Garden – The Architecture

I can see that my last post was on 12th June so it has taken quite some time for me to finally get Phase 1 of this project to completion. Now, I plan on writing close to 4-5 posts entirely on this phase 1 for Garden IoT. Before we jump right in I’ll start with 100 ft view of how does this look like and what’s involved in this project. Following diagram gives good idea about what’s involved in project,…

New beginning … IoT Garden

New beginning … IoT Garden

The Background I’ve been away from the writing scene for far too long. I thought to myself now if I don’t start on this now, I never will! So here it is me trying to get out of my default “procrastination mode” and write something up useful (maybe!). I have couple of things to write about but let me start by writing about something I am recently working on as hobby project. I had a technical event in my company…

Go with Atom for Go-Lang

Go with Atom for Go-Lang

Recently I became docker advocate for out teams here in Pune, if you are thinking what does it actually mean, well I have to ramble about how cool docker is and how can we use it for our advantage till person / team across me says “Alright ! We get it, docker is awesome, lets use it” 🙂 One curious thing that I found while my travels through dockerized world of container as service is docker is written in new language around…

Laziness pays off !

Laziness pays off !

I think software engineers are supposed to be lazy as far as development is concerned. Confused ? Let me explain, software engineers are supposed to write good reusable code so that they won’t have to write same thing over and over again, hence be lazy ! I know this sounds funny, but recently while working on my own project as described in my previous post, I had a chance of being “lazy” so I wanted to share the experience on…

Opening Act

Opening Act

It has always been really hard for me to think of something really nice as opening act, this time I have deliberately tried not to think of anything for opening act, instead let me directly jump into who I am and what am I doing here without wasting your time ! I am Sid, working professional (!) for an MNC company in security domain. Like 10% other ppl of my experience, I am not too happy with limited things I…
