The turbidity of water refers to the degree of turbidity caused by suspended substances such as silt, clay, organic matter, plankton and microorganisms contained in the water. Industrial-grade turbidity sensors or turbidity meters are expensive, and the cost is too high in the design of electronic products. Therefore, we have selected a turbidity sensor that is widely used in household appliances, washing machines, and dishwashers. The sensor uses optical principles to comprehensively judge the turbidity through the light transmittance and scattering rate in the solution. Inside the sensor is an infrared tube. When light passes through a certain amount of water, the amount of light transmission

depends on the degree of dirtiness of the water. The dirtier the water, the less light it transmits. Light

The receiving end converts the intensity of the transmitted light to the corresponding current size. The transmitted light is more and the current is larger. On the contrary, the transmitted light is less and the current is smaller.

The turbidity sensor module converts the current signal output by the sensor into a voltage signal and performs AD conversion data processing through the single-chip microcomputer. The remodelling module has analogue and digital output interfaces. The analogue quantity can be sampled and processed by the single-chip A/D converter to know the current water pollution. The digital value can be adjusted through the potentiometer on the module to adjust the trigger threshold. When the turbidity reaches the set threshold, the D1 indicator will be lit, the output of the sensor module changes from high level to low level, and the single-chip monitors the change in level To determine whether the turbidity of the water exceeds the standard, so as to warn or link other equipment. The module is inexpensive, easy to use, and has a high measurement accuracy

It can be used to measure the degree of water pollution of products such as washing machines and dishwashers; it can also be used in industrial field control, environmental sewage collection and other occasions that require turbidity detection and control.

PIN DIAGRAM

The composition of the turbidity sensor module is shown below. The module is connected to the turbidity sensor through the 3Pin XH-2.54 connector. Adjust the knob of 10K blue potentiometer to adjust the trigger threshold of digital output.

The module pin definitions are as follows:

  1. VCC: Positive supply voltage, 5V cannot be used 3.3V
  2. AO: analogue signal output, output voltage range 0~5V
  3. DO: digital signal output is less than the set value and outputs high level; greater than the set value and outputs low level
  4. GND: negative supply voltage

Specification:

  1. Working voltage: 5.00V DC
  2. Working current: 40mA (MAX)
  3. Response time: <500ms
  4. Insulation resistance: 100MΩ (Min)
  5. Analog output: 0~4.5V;
  6. Digital output: high/low level signal (the corresponding threshold can be selected by adjusting the potentiometer)
  7. Operating temperature: -20℃~90℃
  8. Module size: 38.6mm*22.1mm
