Hi! In class, we have a final project assigned to us. We chose to build an air quality device, similar to the air owl quality. We are using an arduino 101 board, and coding through arduino. The only thing we did not do according to the guideline, was get the dust sensor listed on there. The dust sensor is no longer sold, therefore we ordered a waveshare dust sensor. We followed a guideline, posted by a user (link above). We have managed to get everything set up and connected, but the blynk app does not display the values of the dust sensor. Is the issue the dust sensor, the code, or the app? What should we do to fix it?
