Dust sensor arduino

We based our work on the excellent post over here but contrary to the author, we did not try out multiple sensors and we are using an Arduino Fio. In addition, we will try to provide European shop . Step 5: Sample Source Code. To get the result, please download the sample source code attached below and upload it into Arduino.

An infrared emitting diode and a phototransistor are. Below is a list of tutorials and projects that use this . Abstract: Read value of PMPM2. 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 . It is especially effective in detecting very fine particles like cigarette smoke, and is . This sensor can provide . LPO time is proportional to PM concentration. Copy and paste the demo code below to a new Arduino sketch. Interface to Shinyei Model PPD42NS Particle Sensor.

Program by Christopher Nafis. The outline diagram shows the connection order: enter image description here. As you can see from the image in the second row pin is closest to the edge of the unit. In your image that is red.
