Product introduction of 1. dust sensor MDSM501:
MDSM501 is in the original DSM501ABased on the improved model, the adjustable potentiometer (factory calibration) is removed under the condition that the external dimensions are consistent with the former. Also improved the original DSM501AThe internal signal processing circuit makes the product output linearity better than before and improves the measurement accuracy of the product.
The MDSM501 can sense the smoke and pollen produced by tobacco, house dust, etc., heat the automatic air intake device, and the adjustable resistance is set to detect the size of the dust. Based on the same principle as the particle calculator, the absolute number of particles per unit volume is detected.
