This non-contact turbidity sensor detects water quality by measuring the level of turbidity. Based on the optics principle, it is capable of detecting the light transmittance and scattering rate of the liquid in transparent cylinder containers with a diameter of 40–50mm, which will then be output as an analog value within a certain range that reflects the level of liquid turbidity.

The turbidity sensor comes with two infrared probes, which should be oppositely installed on a container. And it detects when the liquid level inside is higher than the two probes. The sensor can measure without coming into contact with liquid, making it less susceptible to corrosion from water or chemicals.

    Plain-language definitions for the technical terms used above.

    baud
    Baud is the signalling rate of a serial connection, often used as the speed setting for UART communication. Matching the baud rate matters because both connected devices must use the same setting for readable data.
    Gravity
    Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.
    Transmittance
    Transmittance is the fraction of light that passes through a material or layer rather than being absorbed or reflected, usually given as a percentage. A higher transmittance means more light gets through, which can produce a brighter or clearer result for the same light source.
    UART
    UART is a simple asynchronous serial interface that sends data over separate transmit and receive wires, usually labelled TX and RX, with both ends set to the same baud rate. It is a common way for microcontrollers and other serial devices to exchange data.
