CAMBIKE SENSOR

Dear CamBike enthusiast,

Time is running - it’s February already! But we have not been idle, read on for some pretty interesting data from Scotland and India! Also, we’d like to advertise the CO2 workshop at the Centre for Computing History on the 16th of February. And, last but not least, if your sensor seems to have some trouble, you can always let us know and we’ll have a look at it.


Highland Cycle Campaign

Highland Cycle Campaign (highlandcyclecampaign.blogspot.com) used a couple of CamBike sensors and already got some really interesting data! We would like to thank HCC secretary Anne Thomas for organising this! Also, have a look on their Facebook page (facebook.com/HighlandCyclist/), there you can find more maps!

PM 2.5 data from Inverness. Higher values can be seen on the Kessock bridge and in the city centre. The overall air quality seems to be slighly worse than in Cambridge.


Data from India

Two volunteers went to India last month and collected data both indoors and outdoors. The sensor didn’t catch GPS inside but we can still plot the measured values over time. We can also see some interesting variations over the day.

PM 2.5 data taken inside a house in India. Clearly there are variations over the day.

As you can see, the levels are much higher than in Cambridge (between 7 and 20 times to be more precise). India has been developing rapidly and unfortunately high air pollution is one of the side effects.
And of course we don’t want to miss out on the opportunity of showing you some maps! Here is data from a train ride approximately 200km north of New Delhi:

Data collected during a train ride. PM2.5 values are around 20 to 85 times higher than those experienced in Cambridge.


Closer to home: checking volunteers’ sensors

Some of the sensors have been on the road continuously since September and we think it is high time for a check-up. If you notice that your sensor takes longer to find GPS signal than it used to (or anything else seems to have changed or is not working anymore, inlcuding unexpectedly high PM values), we would like to ask you to bring the sensor to the Department of Chemical Engineering and Biotechnology and we will give them a makeover. As always, feedback on how they are doing and what could be improved is very welcome!


What’s next?

We would again like to point out the CO2 sensor workshop at the Centre for Computing History on the afternoon of the 16th of February (a Saturday), booking is available on this website: www.computinghistory.org.uk/pages/30677/What-s-On/. The fee includes entry to the museum for the day - believe us, it is definitely worth it!
Also, the first trip to Nairobi is coming closer and we are starting to make preparations - we are currently awaiting some sensors to begin testing and starting to get an idea on “how the electronics will work”.


Until next time,

The CamBike Sensor Team
