Modular Low-Cost Radiation Detector for Teaching Labs


We have improved on previous low-cost Silicon PIN diode radiation detectors by introducing a novel esp32 board which is capable of transmitting data via wi-fi to our web-app, which will be the designated analysis platform. From our website, students can have a quick refresher on how particle accelerators and detectors work and then there is a comprehensive list of all the easily available components they will need. Then we have a detailed tutorial for students to follow on how to build their very own particle detector. Once they synchronise their device with our web-app, they’ll be able to upload their data for analysis. What we are showing you is a prototype working with simulated data but we are confident we will have a fully working prototype in the next few days. No longer will such experiments be far reaching. We bring them right to your desks!

Technologies used

We have used webpage development and python integration on websites. In addition we have used the innovative esp32 board to connect the detector with the web-app.


Connecting the esp32 board with the web app developed which is our main challenge now. In addition, figuring out the optimum structure of the detector.


Creating the tutorials on our webpage and getting low-cost equipment for the particle detector. Lastly, having a functioning website with a user-friendly interface for students to guide through.


We've learned how to work and collaborate in a team remotely and assign tasks to individuals. In addition, we've gotten more comfortable with creating websites and building particle detectors

Next steps

To perfect the design of the detector and finish off the step-by-step tutorial and connect the esp32 board with the web app. Finally, get in touch with high schools to start getting feedback on our design.
