Panasonic's SN-GCJA5 laser type PM sensor is an addition to its already broad range of specialty sensor solutions. It is comprised of an on-board microprocessor, micro-fan, and laser diode. This sensor has been programmed so that the fan will operate based on the amount of particle dust surrounding the laser diode so that overall lifespan or usefulness of the sensor can be extended much longer than its average commercially available equivalent.

Featuring a very small footprint of 37 mm x 37 mm x 12 mm, the Panasonic laser type PM sensor (PM1.0, PM2.5, PM10) can be used to detect a wide variety of PM including, but not limited to, dust, fly ash, soot, smoke, aerosols, fumes, mists and condensing vapors, solid fuels, construction materials, cooking/smoking of plant matter, fireplaces and furnaces, house/forest fires, waste incineration, and much more. Complete with a cable to connect to your BlackBoard/Arduino device and breadboard!

Note: We've created an Arduino library to make reading this sensor super easy. Find it in the library manager by searching SparkFun Particle.

• Panasonic Eval Kit Manual - Not very helpful but Panasonic did create a Windows app but we cannot find the Arduino sketch they reference.
