UART Non-contact Optical Turbidity Sensor

This non-contact turbidity sensor detects water quality by measuring the level of turbidity. Based on the optics principle, it is capable of detecting the light transmittance and scattering rate of the liquid in transparent cylinder containers with a diameter of 40–50mm, which will then be output as an analogue value within a certain range that reflects the level of liquid turbidity. The turbidity sensor comes with two infrared probes, which should be oppositely installed on a container, and it detects when the liquid level inside is higher than the two probes. The sensor can measure without coming into contact with liquid, making it less susceptible to corrosion from water or chemicals. Connection Example - Turbidity Sensor to DFRduino UNO R3 Features
