I heat with aIt is suppose to be a clean stove. I was interested in the impact on both my inside air (ie. ash/dust) and outside air (smoke). at several locations around the State. Certified Allergy & Asthma Consultants in Albany NY published daily The American Lung Association has a great article called that talks about Particle Pollution. I have several weatherstations collecting data ( There are several citizen group projects that are developing open source equipment (e.g. recent discussions about adding a Particulate sensor.

The Egg Project aims to give citizens a way to participate in the conversation about air quality. It is composed of a sensing device that measures the air quality in the immediate environment and an on-line community that is sharing this information in real-time. It is a community-developed, open source project that is driven by people who care about the air they breathe.3q ionic air purifier tower is a true Laser Particle Counter with two different size ranges. priddy clean air duct serviceThe small channel (0.5> Micron) should see bacteria and mold.olee plasmawave air purifier review The Large channel (2.5> micron) should see dust and pollen. The LCD display constantly shows bargraphs and values for the small and large particles.

unit saves 30 days of air quality data. I ordered the unit with the PC Interface Option and connected it to an Arduino Ethernet so I can automatically log the data to That way air quality alerts can be triggered and sent to twitter and my cell phone. The unit is amazingly sensitive. It easily sees the dust kicked up from walking on a rug or the vapors from cooking. Looking at the graphs below you can see some interesting things. First you can see that things settle down at night when people are not walking around. You can see around noon that my daughter cooked lunch. long it takes for the fine particles to settle down. An Arduino Ethernet is connected to the Sharp sensor following the schematic in the The LED connected to pin 2 is turned on, after 0.28ms the analog pin A0 connected to Vo is sampled. 0.04ms later, the LED is turned off and 9.680ms is waited before the 10ms sequence is repeated I used a small 40mm fan to help make sure air was circulated thru the Sharp sensor.

This probably is not required, but since I am mounting one of the sensors outside in a radiation shield, I wanted to make sure I saw any pollen The Pancake test :-) When you read the Sharp GP2Y1010AU0F Spec sheet Fig. 3 shows a Dust density (mg/m^3) versus voltage graph. But the graph starts at over 0.5 VDC. Unfortunately for most of my tests, the voltage was much lower. I entered the values off the graph and calculated a linear equation to approximate the mg/m^3 values. With the inexpensive Sharp sensor, I wanted to see how sensitive it was and I wanted to try to correlate the voltage to some meaningful metric. I tried a quick match test (blew out a match and let the smoke goThe smoke quickly saturated the sensor. I wanted a longer term test. After seeing that the dylos sensor could see my daughter cooking lunch, I decided to do a "pan cake" test. Did you ever notice that after making pancakes in an old cast iron fry pan with butter, that the kitchen hazes up.

I set up both the Dylos and Sharp sensors to capture the data to Pachube. This allowed me to compare/calibrate the sensors. The two graphs are amazingly similar. Applying a simple offset and multiplication factor allowed the data to be overlaid. The interesting thing is that Dylos has a chart to rate your air relative to other residential environments. The pancake test exceed these by 50X. So there is some question of how sensitive the Sharp unit is at very Other types of real-time data have sites that users can share their data with the global is a great place to store my weatherstation data. is wonderful for processing distributed lightning detectors data to produce real-time maps. Pachube ("patch-bay") connects people to devices, applications, and the Internet of Things. As a web-based service built to manage the world's real-time data, Pachube gives people the power to share, collaborate, and make use of information generated from the world around them.
