#AIRBEAM SENSOR HOW TO#

I tried to delete it from AirCasting, but I realized that it does not let you delete any of the data once it has been sent to CrowdMap. The data was still collected and used as an average for Mountain Brook. For example, on one extremely cloudy day, it started raining after I collected data near Mountain Brook. Note: Although only three days of data are mentioned in this article, I actually tried to collect data on more days. After messing around with the maps and sensor data, I realized that no particulate matter readings were recorded, because only the sound sensor was working near Jackson-Olin High School. On the first day of testing, I unfortunately forgot to take a pic near my first site, Mountain Brook High School, but I was able to take pictures of my other two stops.įor Jackson-Olin High School, AirCasting was not displaying the air pollutant data, only the decibel reading of the AirBeam’s microphone. The weather on the three days I tested were, coincidentally, quite different. If you would like to conduct your own data collection study, you can print this sheet out. I created a sheet that helped me organize the data collected. I also tried my best to avoid highways, because I wanted to collect data in areas that were in close proximity to people that were outside. In order to get the most accurate results, I decided that it would be best to test the air quality on three different days, using the same path each day, and starting the testing around the same time. I just wanted to emphasize that I am a law-abiding citizen, and that jail would seriously deter my plans to graduate college in 2018. I did not test the data on school grounds, because it’s against the law unless consent is given by the schools, but I would park around a minute away from each high school and collect the data on a public road. The reason why I chose those three high schools is because they are in different areas in Birmingham, and each high school represents a different socio-economic bracket. I decided to test the air quality close to three Birmingham city high schools: Mountain Brook, Homewood, and Jackson-Olin. It’s also important to remember that the AirBeam is not waterproof, so if it starts raining, you should take the AirBeam inside. This will increase the accuracy of the data collected. And if you decide to orient the AirBeam standing up, it’s better to flip the AirBeam so that the bottom of the AirBeam is in the direction of the wind. The way and where exactly you decide to orient your AirBeam is up to you, as long as the intake and exhaust areas of the AirBeam are pointing to the outside. On one day of testing, I was driving a different car so the orientation of the AirBeam was standing up instead of lying down. Sometimes the AirBeam would move around if I drove too fast, but for the most part, its movements were really small. This allowed the AirBeam to be securely placed at the top of my car. The sunroof was closed almost completely shut, except for a tiny space to allow the rope to go through.

To learn how to connect the AirBeam to your phone, and how to operate AirCasting, check out my previous blog post here. The alarm system on receiving the warning signal gets activated and as per its programming reacts to the intrusion situation by giving a loud sound.Once I was able to understand how to connect the AirBeam to my phone, and to input data into its open source map, AirCasting, I was finally able to test the pollution around Birmingham.The changed intensity is measured by the receiver and it considers the change as an attempt of intrusion thus sending a warning signal to the alarm system.Whenever someone comes in the path of the waves, the beam gets distorted and the amount of light reaching the receiver gets changed.If the beam is travelling to the receiver without any interruption, the security alarm system attached with the Photobeam sensors is at rest.

The output of the IR receiver is generally small and amplifiers are used to amplify the signal so as to utilize the signal as per the requirement.

The received Infrared is further processed depending upon its intensity.

Depending upon the sensor type, the receiver either receives the transmitted waves directly or after reflection from a fixed object in front.

The transmitted waves are received by the photodiode inside the receiver.

The Infrared LED present inside the transmitter continuously emits IR waves in a straight line that travel through the transmission medium.

The beam sensors work in the following sequence:.
