3.3-5V Turbidity sensor Module

Product Description Turbidity is the measurement of particles in the water. It must be read by the analog MCU port for calculation. It needs turbidity calibration fluid to calibrate. This is not for measuring voltage directly with multimeter. The output voltage of each module is different. The module should be protected from light and the temperature of the light should be used. The voltage will make the module output different voltage, 0-4.5 is only the reference voltage. Parameter: Voltage: 3.3-5 V (with anti-reverse circuit) Output: default analog (can set high and low output) Measuring range: 0-1000 NTU
