We are also looking into building a newer version of the sensor hub that will measure more air quality indicators (such as NO2). Around one of those new sensors, we will organise another workshop at the Centre for Computing History (www.computinghistory.org.uk). With lots of lessons learned at the workshop in summer, we will not solder a whole sensor hub but will concentrate on the principle behind one sensor and its interface with a computer. Read on for more information (and visit the Centre’s website in the next few weeks, where booking will be possible).
Almost there: the sensors are working
Yes, they are working, but the PCBs and sensors still have to be put into their boxes. The testing was finished last week, but we ran into some trouble because the SD cards are now mounted too high above the board (we changed their position slightly to avoid them getting stolen).
We are currently fitting the sensors in their boxes. We have to take care, though, to fix all components in place with small screws to make sure that they don’t come loose when you ride down a bumpy road
Upcoming workshop at the Centre for Computing History
Mark the afternoon of Saturday, 16 February, in your calendar! We will organise a workshop aimed at children aged from 10 onwards. We will tackle the myth that children fall asleep in class because they are lazy and not paying attention - or is it rather that CO2 levels are getting pretty high when 20 to 30 people are in a room and the windows are closed? We will connect the sensor with a computer and do some basic coding to read out values and display them. No previous knowledge is required.
What’s next?
Work on the next generation of sensors will start soon and the database changes are almost completely implemented.
