NIR Spectroscopy and Cobalt Electrochemistry Data set for Estimating Phosphate Concentration in Hydroponic Solution

These data are raw-data used in the development of phosphate sensors for quantitative detection of phosphate ion concentrations in hydroponics nutrient solution. A total of 80 samples were used, of which 56 were used for model development and 24 were used for validation. See below for more details. 1. EMF response data from three cobalt electrodes 2. The intensity value of the sample obtained from the NIR spectrometer (904 nm to 1600 nm
