The optical sensor of this module can measure the density of turbid water and the concentration of extraneous matter using the refraction of wavelength between photo transistor and diode. By using an ...

Note that with the “DFR” sensor, we get a signal output very close to VCC (in digital mode) when the sensor is not submerged or is in clear water (and a bit lower than that in analog mode). Here’s one ...

This article presents the calibration and the analysis of the data being gathered by the proposed alternative low-cost Microcontroller-based Sensor Device that is capable of measuring several ...
