The only way I could get around that is by throwing away 2 of every 3 data packets to insure I'm getting real counts, which increases the total sample time.
For each Plan, a copy of the geometry that was used for the simulation. In a cleanroom we're looking at very low particle counts, and two successive samples might well be identical. The Features group is also your RAS Mapper digital playground - you can add. For a normal home or outdoor setting you could simply discard any reading when the checksum is identical to the previous data, as you're highly unlikely to have two successive samples with the same values. That means it may duplicate over half of the data, with no way to verify whether any reading is a duplicate. With small change between readings the sensor only updates the counts every 2.3 seconds, although it outputs data every second.
DUPLICATE PARTICLE PLAYGROUND ISO
We're only using the sensor for a rough check on current air quality, not to verify compliance with ISO 14644.Ī frustrating artifact of the PlanTower sensor is the sampling rate versus data output. The PlanTower sensor compares favorably with the readings from our calibrated Beckman Particle Counter, although the 30-50% uncertainty on the PlanTower 0.3 and 0.5 um bins means you can't get an exact comparison. And the sensor should not be checked with any third party equipment." Several groups including have done exactly that, and we have as well. One amusing note in the translated PlanTower datasheet is " Only the consistency among the PM sensors of PLANTOWER is promised and ensured.
