The liquid turbidity sensor is composed of an infrared transmitting module, a receiving module, a temperature compensation module, a signal output module and a CPU microprocessor.
Different turbidity liquids have different attenuation to infrared light, and the receiving end deduces the turbidity of the measured liquid by calculating the attenuation of infrared light.
This product has automatic temperature compensation function, which is more accurate and can output analog or digital turbidity signals for users to choose.
