Onboard diagnostics OBD is an automotive term referring to a vehicles selfdiagnostic and reporting capability. OBD systems give the vehicle owner or repair. The Serial Graph Tool for the Arduino Uno provides a simple interface for graphing data to the PC from the Uno. It can graph up to 8 separate channels. Ive finally decided to put some of my existing projects up on instructables. This one is adapted from my Super Graphing Data Logger project. What is the Super. Monitoring your Air Quality.

There are several citizen group projects that are developing open source equipment e. Air Quality Egg. There are several. 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. We Love Golf Wii Iso Torrent more. It is a community developed, open source project that is driven by people who care about the air they breathe. DC1. 10. 0 Pro Air Quality. Laser Particle Counter with two different size ranges. The small channel 0. Micron should see bacteria and mold. The Large channel 2. The LCD display constantly shows bargraphs and values for the small and large particles. The. unit saves 3. I ordered the unit with the PC Interface Option and connected it to an Arduino Ethernet so I can automatically. 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. You can see around noon that my daughter cooked lunch. Its surprising how. The hardware set up is very easy. If you order the Grove Shield, you just need to put the stacking headers on the Arduino Ethernet and install the shield. Plug the Grove dust connector into Digital Port 8. Without the shield, you can just cut the 4 pin connector off, and solder header pins to the wires. JST Pin 1 Black Wire Arduino GND. JST Pin 3 Red wire Arduino 5. VDC. JST Pin 4 Yellow wire Arduino Digital Pin 8. PPD4. 2NS Spec. Sheet. The interface is fairly simple. You just measure how long the digital signal on Pin 8 is low during the 3. This ratio is used in a transfer function to calculate the particles per 0. Grove sensor and printing the. Pachube feed. You need to edit this sketch to use your own feed id and key.
