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.

Art of getting into group is something special which is not only practiced by human beings but also by birds and animals in the nature. We get together on various occasions- it might be birthday function, school cultural function, college induction function, office joining function, marriage function etc,. It is not an easy task to assemble people together and make necessary arrangement for the invitees resulting in success of the event. Whichever functions I mentioned before are joyous moments and there is no reason for people not to join the same unless they have other commitments or complain about the organizer.
But there are certain get together which tests the character of the people. A local rowdy element with political backing harassing the people for money and doing illegal business. A person decides to protest against the rowdy and requests the backing of the other like minded people. Now the repercussions of such a protest can be anything as it is surely going to create a discord between rowdy and the protestors. If you don't protest you are surely going to be identified as supporter of acts of rowdy. Though risky it will create a kind of self confidence of treading the right path despite the opposition. Next comes getting together for wrong deeds, a group formed specifically for committing organized crimes like chain snatching, robbery, murders and rapes. They don't practice remorse and only believe in hunting the weak.
Last but not least we get together in the name of caste, religion and language giving life to concept of majority and minority. This group is the most vicious type among all the fore said groupings. Because it directly attacks your freedom to select and deliver. A majority group thinks that it has every right to influence and take decision on behalf of the minority group. Any protesting voice will stifled with its archaic laws. For them maintaining a fake decorum means more than actual problem to be solved. They feel proud of every tom dick and harry who list out vague accomplishments of majority. They defend the undefended and give impetus to forceful implementations.
Breaking the influence of all the wrong groups is possible but influence of the group which feels proud of being a majority is definitely worrisome. Getting into sides just because they are majority, powerful or intimidating is not at all appreciated. Follow the path of good principles, by giving importance to principles we will definitely land up being in the vicinity of good individuals.
As soon as you are born you are categorized. You are categorized as either black or white, next categorization will be as boy or girl, then categorized as high caste or low caste, further categorization of this religion or that religion, next classification as rich or poor, also you are classified based on your education level etc. This list can go on endless. As and when human finds a difference he categorizes and labels them.
As the net of information technology spreads wider new categories are created and new lists are defined. I was just wondering what were these classifications achieving in practical world. First and foremost these lists find the way into admission of kid into a school. The correspondent has a checklist and ticks the same to decide the child he intakes. Next application of this classification would be while securing a job in a company, classification is also used while selecting a bride or bridegroom. So the application of classification is extended throughout the society.
This segregation of person in the society acts as an indicator in deciding how he/she should be routed within the society. But this entire process is hijacked by the narrow minded people who self appoint themselves towards task of protecting the particular category of the people. For example there are women welfare organization to protect the rights of women. child welfare organization to protect the rights to children, language welfare organization, caste welfare organization, religion welfare organization and so on. There is nothing wrong in a person being feminist but when the person begins to put the entire male bastion into the cage of guilt just noting the wrong doings of few then it is absurd. Similarly there is nothing wrong in vouching for your language or religion but when that turns out into an act of creating enemy character and trying to spread quality of hatred, it portrays poor picture.
Recently there is a clamor to appropriate particular land based on language or religion. Such disoriented forces should understand the ability of force in expanding reach of language or religion is very much limited. External people don't shortlist a person based on language or religion but based on their talent and humility. By reading the life styles of great people like Mahatma Gandhiji, it helps you get enlightened to the fact that you are tied with threads of classification by the society to limit your thinking ability. Once you realize this fact, you can untie yourself and feel essence of being HUMANS OF THE UNIVERSE who can think beyond the boundaries of sex, caste, creed, religion to understand that it is only language of LOVE that can upgrade us during our lifetime.
Heated conversation between two people, each one listing the complaints against each other. None of the two knows why are they acting like they are and not sure what is their ultimate conclusive act. Situation is just getting OUT OF CONTROL.
Believe me, there are cent percent chances of we getting ourselves in above situation wherein we would be arguing with the opposite just to satisfy our ego and there is no big outcome to be proud of. Just few days later we try to recollect the incident and we feel absolutely fooled by situational emotion. There is also chance that you don't accept this and be happy with your ego. There is no big loss with this kind of emotional bankruptcy until it is within limits. That is there is no problem while you are walking and you fall down due to loss of control but there is considerable damage you driving a bike at 60kmps and fall down due to loss of control. The big question arises on how to prevent this loss of control in our life. Many will argue that it is an experience which you cannot prevent. Accepted. There might be less chances of preventing the mishap but proper use of safety equipment shall minimize the impact of such mishap. So what is exactly that safety equipment.
Safety equipment is nothing but our belief in truth, non-violence and immunity to negative emotions.
Having mentioned about non-violence, no one has practically demonstrated the benefits of non-violence to the world as been done by our beloved Mahatma Gandhiji. He lived for that, he died for that.
Some people like to argue that non-violence is coward's weapon. A simple analogy would be curing a patient suffering from pain due to unidentified disease. Doctor has two possible ways to cure the disease. One way is to operate the patient which might involve considerable amount of blood loss and damage to internal organs but immediate relief from the pain. There is no guarantee that pain shall not reappear. Second way is to be on a regular medication and following proper diet practice which shall cure the disease gradually and reduce the pain over the period of time. Hence a non-violent person is much stronger than violent person who can endure pain for longer period just to make sure the situation gets cured properly. And we are
celebrating 150 years of Gandhiji and is a best occasion to recall his
unmatched service towards the idea of bloodless force capable of gaining
the attention of power drunk people towards the world of humanity and
equality. The idea of non violent non co operation inspires many around
the world and has instilled the belief that there is a big power which
can traverse the boundaries touched by sticks, guns and bombs. You just
need a backing of convincing ideology, you raise your fist and your
voice. You are the ultimate power in the world which no one can ignore.
Celebrate 150 years of Gandhiji by sharing this post.
