Introduction to turbidity sensor:The turbidity sensor USES the optical principle to comprehensively judge the turbidity by the light transmittance and scattering rate in the liquid solution.Since the turbidity value is an asymptotic variable, 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: DC5VWorking current: 30mA(MAX)Response time:Less than 500msinsulation resistance: 100 m ohm/Min.Output mode 1:Simulation output 0-4.5vOutput mode 2:High/low level signalHigh level: 5VLow level: 0VOperating temperature: -30 Celsius -80 CelsiusStorage temperature: -10 - 80 CelsiusApplication scope:Washing machines, dishwashers, industrial site control, environmental sewage collection and other occasions where turbidity detection and control is required;Colour:Black + blueMaterial:plasticSize:30mmx20mmx12mmPackage Contents:1* Turbidity Sensor kitOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
