Deviyon aur Sajjano namaskar

Its my 100th post on my blog and I couldn't ask for something more. Though a lot can be written about my blog journey but less said is more. I would like to thank google for providing the platform for dissemination of my ideas through the virtual space. An interesting insight is that my post about Father of nation, Mahatma Gandhiji has garnered highest views amongst all the post till date. And there are some people trying to convince me that days of Gandhian is over.

 Apart from cherishing the track record, I want to share my point of view about latest buzz in fintech industry known as 'IOT sound box'. Yes, little piece of crap that you find in almost all kirana stores near you. I wonder why would someone like that his/her transaction between giver and taker should be broadcasted on a loud speaker. 

Interesting thing about sound box is that it is available on a monthly rent from fintech companies. Though it saves kirana store owner from hassles of scrolling the smart phone each time to verify payment but that should not be a point of contention to fall back w.r.t. sound box.

 

 

Its easy to figure out a problem but suggesting the alternative is not a child's play. Best alternative would a be paper/ digital audit trail, a technology used in EVM system. Some may argue that we receive receipts on payment through a app, but the primary point would be about acknowledging authority. I mean who is acknowledging your payments, it is definitely not from the receiver of the payments. You continue to be at the mercy of fintech platform providers.

ONLINE TURBIDITY METER

Hi Friends,

Today I am going to share some information about ONLINE TURBIDITY Meter integrated by me. 

Turbidity is the cloudiness or haziness of a fluid caused by large numbers of individual particles that are generally invisible to the naked eye, similar to smoke in air. The measurement of turbidity is a key test of water quality

Turbidity meter measures the quality of solution measured in NTU which stands for  Nephelometric Turbidity Unit. A clean solution will have 0 NTU whereas a contaminated solution will have greater than Zero value proportional to amount of contamination.

A block diagram of Online turbidity meter is as below:


As seen from the diagram, PIC Micro-controller measures the turbidity sensor value using the inbuilt A/D converter and displays the same on the OLED in NTU units. The same value is transmitted to Google spreadsheet using ESP-8266 01 wifi module which makes the project a variant of IOT application.

The demo of the project is as given in the below video. 



This is basically a proof of  concept. The same can be developed into full fledged device for a cost of as low as Rs.4,000/-. Please feel free to contact me if you are looking for a similar device so that I can arrange one for you.
