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 ...

As a real turbidity sensor (which is sold in electronics stores) usually has a high price, the idea of this project came to replace such equipment with lower-priced ones and obtain a similar result.

An infrared proximity sensor, or IR Sensor, is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This interfacing of the IR sensor module with Arduino is ...

The turbidity has been classified as a basic item to measure water quality. This research team has developed a small turbidity sensor module to measure permanent turbidity based on moving objects that ...
