Public Lab: Optical Monitoring of Particulate Matter

How optical particle sensors work. A sensor and a beam of light sit at an angle to each other. As a particle passes in front of the light, some light is reflected towards the sensor. The sensor registers a pulse for as long as the particle reflects light to the sensor. If the air is moving at a consistent speed, the length of this pulse can be used to estimate the particle’s diameter. Read more in-depth in this …

How to Interface With Optical Dust Sensor : 9 Steps (with …

Sharp's GP2Y1010AU0F is an optical air quality sensor, or may also known as optical dust sensor, is designed to sense dust particles. An infrared emitting diode and a phototransistor are diagonally arranged into this device, to allow it to detect the reflected light of dust in air. It is especially effective in detecting very fine particles like cigarette smoke, and is commonly used in air purifier systems.

Soot (PM) Sensors - DieselNet

There are a number of temperature sensors that work on the Photon. The TMP36 is an analog sensor, connecting to an ADC input on the Photon. The DS18B20 is a 1-wire temperature sensor, which uses a different protocol than I2C, and uses fewer wires than I2C. The DHT22 uses a proprietary digital protocol and measures temperature and humidity. But in this tutorial we'll concentrate on the I2C temperature …

Soot (PM) Sensors - DieselNet

Extensive work has been done in correlating soot mass accumulation in a DPF with the resulting pressure drop [469][3055][3056]. This approach formed the industry’s initial method to estimate a DPF soot mass, becoming the most widely used DPF soot mass estimation technique. Calibration advances on filter performance have additionally allowed estimating the mass of the ash in the filter using a ∆P …

Would love to hear thoughts from folks as to whether they think I'm on the right track, here. Inside the sensor (see Willie's awesome teardown pic above) is an IR LED and an IR photodiode, both pointing at a particular region of air inside the device. There is a focusing lens, to …

How a detector works | CERN

The detectors gather clues about the particles – including their speed, mass and charge – from which physicists can work out a particle's identity. The process requires accelerators, powerful electromagnets, and layer upon layer of complex subdetectors. Particles produced in collisions normally travel in straight lines, but in the presence of a magnetic field their paths become curved. Electromagnets around …
