Introduction to turbidity sensor:The turbidity sensor USES the optical principle to comprehensively the turbidity by the light transmittance and scattering rate in the . Since the turbidity value is an asymptotic , it is usually detected in a dynamic environment.Therefore, the sensor also needs to make peripheral circuit to detect in the system, with a waterproof probe, mainly applicable to washing machines, dishwashers and other equipment turbidity detection, can also be used in electronic design, graduation design, electronic competition experiments and other applications. Technical parameters: Working voltage: DC5V Working current: 30mA(MAX) Response time:Less than 500ms insulation resistance: 100 m ohm/Min. Output mode 1:Simulation output 0-4.5v Output mode 2:High/low level signalHigh level: 5VLow level: 0V Operating temperature: -30 Celsius -80 Celsius Storage temperature: -10 - 80 Celsius Application :Washing machines, dishwashers, industrial site control, environmental sewage collection and other occasions where turbidity detection and control is required; Colour:Black + blue Material:plastic Size:30mmx20mmx12mm Package Contents: 1* Turbidity Sensor kit Only the above package content, other are not included. Note: Light and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
