Incorporated gas sensors monitor the pollution levels along the roads and inform you via app when and where you should avoid traffic.
An inbuilt three-axis accelerometer tracks the quality of the roads during your journey and identifies unnecessary slow-downs.
Our wireless network across Cambridge allows you to track the position of your bike when you log in to your account.

CamBike Sensor is a student-led initiative from the University of Cambridge. The project aim is to develop a sensor hub that can be mounted onto bikes, allowing you to monitor air pollution, estimate road quality, and track your bike. By encouraging Cambridge residents to assemble and/or use the easy-to-build sensors, as well as access the analysed data, this project will bring the world of science closer to the community and promote engagement with issues relating to the quality of the local environment.

Are pollutant levels on the roads of Cambridge acceptable, or do they pose a health threat? How good is the quality of roads, including the smaller ones that cars don’t frequent, but bikes do? To measure this, we need a system that relies on many different sensors spread across town. Mounting lots of sensors on lots of bikes has the advantage that we won’t need to rely on very expensive sensors, but can still compare the readouts to stationary sensors already present across the city. We cannot do this on our own and so we need engaged and interested citizens like you to help us create this network. By mounting the sensors on bikes, we can measure the air and road quality when you’re in traffic, and cover large parts of Cambridge. The hub will contain multiple sensors. We are using particulate matter sensors to measure the amount of very small particles (PM10) in the air that can enter deep into your lungs and cause inflammation. PM10 include pollutants emitted by cars.
An incorporated GPS module is used to locate the bike while you are travelling. All data are transmitted using low power wireless communication. The system will be self-powered and supported by a battery that won’t have to be charged often. If you volunteer to build the sensor hub, you will need to set up the sensors and connect them to a central circuit board, which will then be encased and put on a bike. Alternatively, you can volunteer to use a pre-built sensor hub for a week, to map your frequently taken routes. The collected data can be viewed interactively using an app on a phone or a computer. The data you collect will be accessible only to you. The overview map of air pollution and road quality in Cambridge produced from yours and others’ anonymised data will be made available online to the community.
