The Arduino turbidity sensor is a great tool for detecting water quality. It measures the turbidity level by gauging the light transmittance and scattering rate, which vary with the total suspended solids (TSS) in water. As TSS rises, the liquid's turbidity goes up. This sensor offers both analog and digital signal output modes. You can choose the mode based on your MCU, and in the digital signal mode, you can adjust the threshold. It's highly versatile and can be used for measuring water quality in rivers and streams, wastewater and effluent, sediment transport research, and laboratory testing. Note that the top of the probe isn't waterproof. Specification: Operating Voltage is 5V DC, with a maximum Operating Current of 40mA. It has a Response Time of less than 500ms and an Insulation Resistance of at least 100M. The Output Method includes analog with an output range of 0 - 4.5V and digital with a High/Low level signal (threshold adjustable via potentiometer). It can operate at temperatures from 5°C to 90°C and be stored at -10°C to 90°C. It weighs 30g and has an adapter sized 38mm*28mm*10mm (1.5 inches * 1.1 inches * 0.4 inches).

Using this turbidity sensor is quite easy. First, connect the sensor adapter, probe, and cables as per the shipping list. Then, power it with a 5V DC power supply. You can choose between the analog and digital output modes according to your MCU. In the digital mode, you can adjust the threshold value by turning the potentiometer. When measuring water quality, place the probe in the water you want to test. Remember, the top of the probe is not waterproof, so don't submerge it completely. As for maintenance, keep the sensor clean and store it in a dry place within the temperature range of -10°C to 90°C. If you have any questions, refer to the Turbidity sensor SKU: SEN0189 Wiki for more information.
