Turbidity Analog Sensor
Turbidity Analog Sensor - The turbidity sensor detects water quality by measuring the level of turbidity. It is able to detect suspended particles in water by measuring the light transmittance and scattering rate which changes with the amount of total suspended solids (TSS) in water. As the TTS increases, the liquid turbidity level increases.
This sensor has both analog and digital signal output modes. You can select the mode according to the MCU as the threshold is adjustable in digital signal mode.
Turbidity sensors can be used in the measurement of water quality in rivers and streams, wastewater and effluent measurements, sediment transport research, and laboratory measurements.
Importance of Turbidity Analog Sensor
Water turbidity matters a lot. It is a crucial measurement unit to check water quality and identify the degree of water cloudiness. Further, turbidity involves small particles that we can see with the naked eye. This is a combination of small and larger particles. Larger (heavy) particles are used to settle down quickly, whereas, small particles take very slow to sit on the floor or not at all!
Human activities such as mining, construction, or agriculture add to turbidity in rivers or lakes. Rainwater also gets melted in these sources coming from urban areas and industries. Hence, all in all, it becomes of extreme significance to monitor the turbidity, especially in the drinking water. Using Turbidity Analog Sensors, one can detect water quality by measuring the turbidity level. Also, the equipment helps you detect suspended particles available in the water.
It can cause diseases to have turbidity in drinking water since bacteria or viruses can stick to suspended particles. If you try to remove those using disinfectants such as UV sterilization or chlorine; it may be a limited success at all with higher turbidity levels. Tap water can obtain lots of cloudiness as it travels through miles of pipelines.
In terms of WHO guidelines, tap water turbidity is recommended to be below 1 NTU. You also should be confirmed about the same by checking the tap water using a turbidity meter. We can notice flocculants and coagulants dosed to water (with high turbidity) in wastewater management procedures. These substances clump together to develop bigger particles and then settle down in sedimentation basins.
Well, measuring the turbidity also depends upon the turbidity standard along with the light source. The process uses white light in the visible range (according to US-EPA 180.1) and the widely-used turbidity methods include;
- Attenuation Measurement
- Scattered Light Measurement
A light beam is radiated through the medium under the attenuation process. But under the scattered measurement, forward/backward scattering is measured at 90-degree.
