1、 Product Introduction of Dust Sensor MDSM501:
MDSM501It's in the original versionDSM501AThe improved model on the basis has removed the adjustable potentiometer (used for factory calibration) while maintaining the same external dimensions as the former. At the same time, it also improved the originalDSM501AThe internal signal processing circuit of the product has improved the linearity of the output compared to before, thereby enhancing the measurement accuracy of the product.
MDSM501Can perceive the smoke and pollen produced by tobacco,House dust, etc,Heating automatic air intake device, adjustable resistor setting to detect the size of dust. Based on the same principle as the particle calculator,Detect the absolute number of particles per unit volume.
