Hey, Welcome this course, learn, apply and build solutions. Please ensure during your development you have copied your devices' authentication details, do not copy what I used. Some few debugs, In azure cloud, to visualize your data, you have to install Azure add-on's using the command, az extension add --name azure-cli-iot-ext. Enjoy, if you have any queries you can as well use GitHub repo (link in comment section) to raise an issue and will respond ASAP. ☁
Great series. I only had WeMos D1 mini with DHT11 shield available (which seems to be suited better for such a small project anyway), so the coding part is different, but with your help I was able to set up IoT hub and all the rest of Azure services. Thanks Aaron!!
Hello, I have to say that is incredibely interesting project. is it possible to easily extract data from cosmos db to a mobile application, e.g. in React.js?
Hello, among the methods to export data from Cossmos DB are : using document db and can use various sources such as JSON, however there are more ways to manipulate your output from cosmos db. Would recommend the two links below: learn.microsoft.com/en-us/samples/azure-samples/react-cosmosdb/react-cosmosdb/ learn.microsoft.com/en-us/azure/cosmos-db/nosql/quickstart-nodejs?tabs=azure-portal%2Cpasswordless%2Cwindows%2Csign-in-azure-cli
Hello and thank you for this interesting project. I was able to understand and implement this, but I see a problem: If the Python script is started, the temperature and humidity are measured and then transmitted at the defined intervals. But the exact same reading is transmitted over and over again, even if the sensor was placed in the sun and the temperature would have to change. Only when the script has been stopped and restarted is the temperature measured and then the new value is transmitted over and over again. This can also be seen in your script (43:01 in the video). Do you have an idea how this can be solved so that it is really remeasured every time at the specified interval?
Hello @tobiaswinter7617, happy you followed and worked for you. Please check your DHT sensor, change it to be sure it works fine. Otherwise another way of troubleshooting, is to only measure the temp & hum without transmitting on IoT hub and exposing the sensor to varying environment for testing. Let me know how it goes.
