Intro, Waiting platform, appliance monitor, weighing machine and Current Sensor
IOT Current Sensor, MQTT Base station and The Raspberry Pi Rover
Prelude My previous post was a textual summary of work done and I just could not shrink it more. In this post I continue by providing demo videos for the project. I try to explain the working and internals without actually tearing down the modules. For that most of my posts in the past have been short in ...
Project Goals and problem statement
System Block Diagram
Modules - Functionality & Applications & Advantages
Module I. The waiting platform- Forget not anything outside the fridge.
Module II. IOT Weighing Machine- Forget not to get a refill LPG cylinder
Module III: IOT Current Sensor- Forget not any of the lights in the house.
Module IV: IOT Appliance Monitor- Forget not the AirConditioner left On
MET MQTT Station
Public Display of Data
Introduction The requirement for this module was to have a weather station that would transmit weather data over the internet to OpenHAB. Why the internet? because we can and because what would an IOT solution be without the Internet. Hence there was a lot to be done. The Sensors The ideas was to keep things in budget and use scrap parts to build a Weather station. I did get some of it workin ...
The Center Piece
IOT Weighing Machine
Arduino MQTT Control with RF receiver.
The Center Piece A lot has happened in the last few weeks and I have not been able to post due to issue. The center piece is the RPi which is now a headless system where I had previously put up this... Which has now been replaced.... I wanted to be portable so that if need be I can work with it as well. Als ...
Current System Design
RPi and OpenHAB
The Waiting Platform
IOT Weighing Machine
Arduino MQTT Control
Abstract I have managed to pull everything together and have put the system into final testing mode. As of today, the whole system is functional and I am in debugging mode. It will run 24x7 like a good system should and it will be used to tackle our problems in re ...
This is a late weekly update and there are many reasons for it which include some urgent work on my PhD research as well a a cold a have. Anyways progress has been kinda up and down where some modules have been completely tested and other have been modified. The EnOceans sensors are very easy to customize and I added another simple application around one so that adds to the total module count. I have also revamped the OpenHAB casing and it looks... different I will be posting pics very ...
The decision - which RF technology is better- AM Modules? XBEE? nRF? Wifi? Bluetooth? TI CCxxx modules?
MET system, CC3200 and MQTT:
IOT Weighing Machine: A Low Power Sensor Network using the CC2500
Step 1. Testing the load cell.
Step 2: Prototype and test
Step 3: Spec and Write the Code
Step 4: Test the code... on the RPi
Step 5: Power analysis... featuring the Tek Scope.
Step 5: OpenHAB integration. The serial binding
The design challenge decision
Problem 1. A household problem of leaving things out of the fridge.
Problem 2: A problem of re-ordering gas cylinders
Problem 3: The Power Meter.
Problem 4:IOT MET system
Problem 5: Window monitor
Problem 6: Controlling the AC remotely
Problem 7: The RPi Rover

Introduction I have been working with MQTT for some time now, especially after a demo by Benjamin Kabe of the Eclipse Foundation on Paho, LWM2M and the related. MQTT offers a light communication method for connected devices. In my project, I have an architecture where the Raspberry Pi acts as an aggregation point for all the local data. This has two advantages. All the local traffic stays local. This means that my home automation system will never be responsible for excessive internet tra ...

EnOcean Modules and Things other than Temperature
Introduction The raspberry pi does not have the conventional x86 architecture for a processor. Instead it has an ARM processor running at 400MHz. Now this means that even though you are running Linux and even though you can compile the same program us ...
Introduction My quadcopter was supposed to take first flight this weekend but since it is now a 'minion battle royale', I thought I would kick it up a notch. Batman was abducted from my workbench and now Pikachu is sitting there alone. I thought Minion Dave would make an excellent addition and hence I am doing this post today instead of tomorrow morning in the hopes that I get a friend for poor pikachu. I received the Scope and the extra RPi B+ AND an additional EnOcean Kit AND the ...
At this point pretty much everyone has explained what they intend to do. I was waiting for parts to be delivered so that I can be sure that I have the resources to actually build my project. I started by building small parts of each module which I had proposed and made sure it was doable. Next I ordered parts and my design went through some changes. Lastly I made a final call on the design and I am going to stick to it. So here is the final design. At this point I understand that its a bit much ...
Introduction I am waiting for my stuff to get delivered which are basically parts and parts. One of features of my design is that the raspberry pi center piece is portable, ie it can be moved from one location of the house to the other. For this I needed to add a battery backup which was shown in my previous posts. In my recent experiments, I found that the Raspberry Pi was rebooting unexpectedly. It turns out that one of the connectors was defective. Still this left me with the question that i ...
As I wait for the parts to be delivered, I started work on the case for the RPi. This is the center piece for my demo and with my limited carpentry skills, I set out to make a box. I usually start by making a 3D to scale model in Sketchup so I know exactly what I want. If it seems awkward, I change it. Here is a simple mockup that took 5 minutes! Next is basically me cutting and scraping and gluing.
Right now I have a Lipo Rider Pro which allows me to make my sys ...
Introduction In my last post, I discussed how to get OpenHAB up and running. For the "Forget me not" Design Challenge, one of the sponsors is EnOcean and they were gracious enough to supply us with a basic kit and EnOcean Pi. This is a brief write up of what "I think" is happening. If someone knows something I don't, please feel free to comment and I will be more than happy to make corrections. EnOcean Pack The EnOcean Sensors are Energy harvesting modules. This means that ...
