Water quality prediction system using formulas in HTML

So this was a project done by me it's genuinely a mix of hardware and software stuffs. So this project basically predicts water quality with few important inputs like TDS, ORP, pH, and a swimming pool testing strip where it goes through certain formulas ad predicts multiple outputs which has been formatted and made sure that it's very much accurate by calibrating it with CBPC ( Central Board of Pollution Control) also i almost was able to publish it to IJEAST ( International Journal of Engineering Applied Science) but could pay the cost of publishing but got accepted
