The sensor uses a laser diode and a photodiode to detect and count particles, while a fan moves air through the system.

Press Release Thermal laser power sensor or photodiode: making the right choice Date Announced: 09 May 2016 Did you ever come across a situation where you had to decide between a thermal laser power ...

LASER COMPONENTS has revamped InGaAs and extended InGaAs photodiode technology, which has led to the development of groundbreaking industrial “Plug&Play” sensors. This new class of universal, purely ...

We can use them to cut things, create laser light shows, and also as a rangefinder. [Ignas] wrote in to tell us about [Berryjam’s] AMAZING write-up on creating an Arduino based laser rangefinder.

Fig 4. Exposing the modified pressure sensor to laser energy created a temperature-induced change in the piezo-resistive element’s resistance that corresponded directly to laser power.
