Back in 1996 an instrumentation scientist retied as Head of University Sciences & Instrumentation Center (USIC) Punjabi University, Patiala. He being a PhD in Electronics and having vast exposure to various scientific methods and techniques was presented the problem that were faced by a few people then. The problem was about sensing water level in water tank and hence help control water pumps to stop overflows.
Many a people have tried by then and many a circuits were published in popular electronics magazines then (like EFY). But most of the circuits were good enough for science projects only as they lacked on reliability and durability - the two must haves for any product especially of alarm and automation kind.
S. Gurmej Singh, Director of University Sciences & Instrumentation Center, Punjabi University Patiala retired in 1996 and focused on the problem presented to him by his colleague friends. It took almost 5 years to build the water sensing circuits from scratch and field testing. Finally water sensing circuits and water sensors were ready as credible products, to be explored for business potential.
Back in 2001 Punjab homes were replacing motorized gearbox pump sets and jet pumps with submersible pumps. But still there were few buyers for product in interior Punjab as water was not big concern then. So, Tri-city (Chandigarh, Mohali, Panchkula) was selected as test market, as there was more need, willingness and ability to opt for such high quality, as offered by then our brand name "aquasens". The product leaf shows, what was products like then. Tri-city was tried with some out of box advertisement and publicity ideas. The methods and the result makes for our next writing- 2001- 2005 Creating A Part Time Business With Credible Product.
