Turbidity sensor module common customer questions:
Q 1. What substances can the turbidity sensor measure in the water?
Answer: The turbidity sensor measures the granular floating objects in the water environment, such as: silt, clay, metal particles, organic matter, plankton and microorganisms and other suspended materials; Not suitable for measuring environmental pollution caused by water such as ink and color materials; There are individual users with a few drops of ink mixed pure water to measure the way is wrong scheme.
Q 2. What signal does this sensor output?
Answer: The sensor control board supports analog and digital signal output at the same time:
(1) AOUT output analog signal, voltage between 0~4.5V; The analog quantity can be programmed to be controlled by the corresponding voltage signal after AD collection of the single chip microcomputer, or the analog input pin of the Arduino controller can be used to read the corresponding data for control.
(2) THE DOUT port outputs the digital quantity high and low level signal, the high level is 1 (about 4.5V), the low level is 0 (about 0.28V); The digital quantity can be controlled directly by collecting high and low level signal states through the single chip microcomputer pin. At the same time, the digital quantity can be separated from the single-chip microcomputer programming, directly connected to a 5V relay module to control the external equipment; Digital signal trigger sensitivity can set the turbidity threshold through the onboard adjustable resistance; Counterclockwise sensitivity becomes higher, clockwise sensitivity becomes lower.
Q 4. How does the analog signal voltage of the sensor output change?
Answer: Measured in indoor natural light environment, the analog signal voltage output by the sensor in clean water is about 3.9V. When the turbidity of water increases, the output voltage changes from high to low, and the lowest value is close to 0V.
Q 4. Why is the analog signal output voltage lower when the sensor is not in contact with water, but higher when it is in clean water?
Answer: This is because the sensor hardware characteristics, the use of photoelectric infrared sensor, in the natural environment is affected by the environmental light infrared signal transmission; But in the water, the output voltage becomes higher, because water increases the refraction of infrared light, but helps infrared light transmission; Therefore, when we set the correct value, we should take the correct value in clear water and muddy water, rather than in the natural environment when the probe does not touch the water.
Q 5. What is the working voltage of the sensor?
Answer: The working voltage of sensor control board is 5V, the highest voltage can not exceed 6V, otherwise the module and sensor probe will be burned out.
