Amphenol Sensors Laser Dust SM-UART-04L
The SM-UART-04L is a laser-based sensor capable that quickly and accurately provides PM2.5 measurements. A fan pulls air into the housing, where a laser LED illuminates the particles and a photo sensor detects reflections from particles ranging from 0.3 to 10 microns.
The SM-UART-04L is easy to use, as the output of the photo sensor is processed by an integrated MCU and the measured concentration levels are output over a UART interface, with a detection range of 1 to 999 micrograms per cubic meter. The laser-based measurement offers a fast 1 second response time and an average of 40,000 hours before re-calibration is required.
