- 8+
- Category
- STEM Robotics & Electronics
- Customisation
- OEM & ODM available
Specifications, component counts and packaging are configurable. Figures shown reflect our standard configuration.
Key features
- Analog-output turbidity sensor based on the GE TSW-20 sensing principle for wash-water and water-quality measurement.
- Infrared LED and phototransistor pair measures opacity: more dirt means less transmitted light.
- Light reflected and transmitted through the sample converts to a turbidity reading — the same principle washing machines use to set cycle time.
- Includes probe and connecting wires; ideal for environmental-science experiments.
Frequently asked about this product
How do I connect the Turbidity Sensor (TSW-20) with Probe & Cable to my controller board?
The Turbidity Sensor (TSW-20) with Probe & Cable uses the standard 3-pin GVS (Ground-VCC-Signal) interface with an XH2.54 connector, so it plugs straight into Arduino UNO, ESP32, micro:bit and our sensor shields with a regular sensor cable — no soldering required. It works with Arduino IDE, Mixly, Mind+, Scratch and mBlock.
What voltage does the Turbidity Sensor (TSW-20) with Probe & Cable run on?
The Turbidity Sensor (TSW-20) with Probe & Cable runs from a standard 3.3-5 V DC supply (USB or the controller’s 5 V rail). It draws only a few milliamps in normal operation, so it is safe to power from the controller board itself for classroom builds.
What projects is the Turbidity Sensor (TSW-20) with Probe & Cable good for?
The Turbidity Sensor (TSW-20) with Probe & Cable is built for STEM and robotics education: classroom demonstrations, science-fair projects, robotics club builds and competition robots. It pairs with the rest of our module range — same connectors, same voltage, same toolchain — so students move from first circuit to competition robot without changing platforms.
What certification do the robotics and electronics products carry?
Controller boards, sensors and modules ship with CE marking and RoHS-compliant components, and the range is designed for classroom use under teacher supervision. Product-specific test reports and declarations of conformity are available for distributors on request.
What is the minimum order quantity, and can I get a sample first?
These are standard catalogue lines with stable production, so minimums are low and lead times are short. Samples ship within about a week and are normally credited against a first order. Mixed-SKU cartons are accepted for evaluation orders.
