DFRobot Turbidity Sensor Module - Non-contact Optical UART Output for Arduino
The DFRobot Turbidity Sensor is a non-contact optical sensor designed for Arduino and microcontroller systems, providing UART output to measure water quality by detecting light scattering in transparent containers with 40–50mm diameters.
Features
- Non-contact optical sensing principle prevents sensor corrosion and contamination.
- TTL UART serial output (9600 bps) for stable, digital data communication.
- Designed for transparent cylindrical containers with 40–50mm outer diameters.
- Low power operation at 5V DC with less than 10mA current draw.
- Includes Gravity 4-pin adapter for easy plug-and-play integration.

The DFRobot Turbidity Sensor operates on an optical scattering principle, utilizing paired infrared probes mounted opposite each other on a container. It measures the light transmittance and scattering rate of the liquid, outputting a calibrated UART data frame that correlates to turbidity levels (NTU). This non-contact design ensures the sensing electronics are isolated from the liquid, significantly enhancing long-term durability in corrosive or chemically aggressive aqueous environments.
The module is engineered for integration into water quality monitoring systems, aquaculture, and industrial process control. It features a compact form factor and communicates via a simple TTL UART interface, making it compatible with a wide range of microcontrollers like Arduino, ESP32, and Raspberry Pi when used with a logic level converter. The operating temperature range supports both indoor laboratory and broader field deployment scenarios.
