I used arduino to run my dfrobot turbidity sensor. Unfortunately, the sensor only reads in volts but i need to run it as ntu (turbidity units). Does anybody have past experiences with this and has the formula/equation/calibration values to get any ntu with the voltage reading of the sensor? I cannot test nor calibrate myself due to the loss of my sensor and the lack of time. This is for my grade school project but the deadline is fast approaching. I really really need your help to be able to pass this year .
What does the data sheet of the sensor have to say about this conversion?
O mais correto seria obter valores de um turbidímetro e montar uma tabela. Logo após fazer um gráfico onde é possivel ter a equação da curva volts x NTU.
