This Dust Sensor gives a good indication of the air quality in an environment by measuring the dust concentration. The Particulate Matter level (PM level) in the air is measured by counting the Low Pulse Occupancy time (LPO time) in a given time unit. LPO time is proportional to PM concentration. This sensor can provide reliable data for air purifier systems; it is responsive to PM of diameter 1μm.

Particles are special graphical effects in Minecraft that are created when certain events occur, such as explosions, rainfall, or smelting items in a furnace. Particles are rendered as frontfacing 2D sprites, meaning they always face the player. They disappear after a short animation, in which they may change sizes and rotate, and cycle between a number of animation sprites. They collide with solid blocks and …
22/05/2019· When using the Wire library (the library that controls the I2C peripheral on the Photon), the bus protocol itself does not need to be understood, but the control bytes and other data packets that need to be sent to. This is why, when using I2C devices, it’s critical that you read the datasheet, especially paragraphs and diagrams regarding reading and writing.
We developed an online measurement setup consisting of a UV/Vis and a light scattering sensor (DLS and SLS) with a unified software platform.
