My project is a weather station in Extremadura (Spain) a land with long droughs, using materials below:
Presure and temperature: sensor BMP280
Humidity: sensor DHT21
Light sensor: ?
From a spoiled PCE-FWS 20 station:
Rain gauge (Excellent tutorial by Rebecca Ricks)
Following Alvaro’s sketch: Create ioT Realtime Dasboards, and changing only bmp280 sensor, and t was succesfull. I can see in my dashboard Pressure and temperature.
Uaaaau! for a newbie like me it was great!
Next step was attaching DHT21 sensor, but…
Trying to do the same thing with sensor DHT21, is not so easy as I thought.
Could someone help me with code have to add in the sketch to read humidity from this sensor?
Thank you very much in advance.
