Water Quality Sensor's Data using Photodiode and LDR in Nephelometric Turbidity Unit (NTU) Scale

The dataset provide the information about sensitivity scale of the Photodiode and the LDR as a water quality sensors in NTU scale. The testing equipment uses PVC pipe ¾ inches and purifies sensor consisting of a 5-mm LED light with 12 V as a 5-mm transmitter and photodiode with 5 V as a receiver. The distance between the photodiode and the LED is around 5 cm. The sensitivity scale testing is conducting to find out the value of the sensors against the changes of NTU values. The test is carried out on the test tube by adding some drops of 5 ml of NTU water which are given gradually to the tube. The water that is used as a reference for the system is the water with a value of 5 NTU. The samples taken were the water samples of the water with NTU value equal to 1 NTU, 5 NTU, 10 NTU, 20 NTU, 50 NTU and 100 NTU.

本数据集提供了以浊度单位（NTU）为计量标准的、作为水质传感器的光电二极管（Photodiode）与光敏电阻（Light Dependent Resistor, LDR）的灵敏度标定相关信息。测试装置采用3/4英寸聚氯乙烯（PVC）管材，其传感组件由供电12V的5mm发光二极管（LED）作为发射端，以及供电5V的光电二极管作为接收端组成。光电二极管与LED之间的间距约为5厘米。本次灵敏度标定实验旨在探究传感器响应NTU值变化时的输出特性。实验通过向试管中逐滴加入总容积为5mL的NTU水样开展，本系统所用的参考水样为NTU值为5的标准水样，本次实验采集的水样NTU值分别为1、5、10、20、50和100。
