![]() Just make up a unique username and send your data to If you have never used Dweet it is very easy to use. Uncomment out the line senddataWU() when you are ready to send data to Wunderground. We suggest playing around with Dweet first until that works and then work on getting data to Wunderground. We have also commented out the line senddataWU(), which sends the data to Wunderground. You will need to put in your Wifi username and password, your Dweet unique name and your Wunderground login details. There are a few lines you will need to change. Here is the Arduino code – ESP8266 Weather Station.Ĭopy and paste this into a new sketch in the Arduino IDE. Connect +V to 3V, GND to GND, SCL to SCL and SDA to SDA. Now add the SHT31 sensor to measure temperature and humidity. This brings the voltage level down so you can read it through the analog pin. The 1M resistor should go to +V and the 220k resistor should go to GND. Have a wire going from pin A to in between the two resistors. Next make your voltage divider to measure battery level. This will make the microcontroller wake up from sleeping. Add a wire connecting pin 16 to the reset or rst pin. Add a wire from 3V to the positive rail on the side of the breadboard and do the same for GND. We soldered female header pin sockets on the ESP8266 so we could add the proto shield on top later. Start with a breadboard and the Feather Huzzah ESP8266. Or you can just download the files and print them yourself. If you sign up for an account, you can have it printed through 3D Hubs from that page. We found our enclosure on thingiverse and had it 3D printed. Right now we only have temperature and humidity thanks to a SHT31 sensor. Upload your own actual data to Dweet and Wunderground. Make a weather station using the Feather Huzzah ESP8266 WiFi Microcontroller.
