Nice project. Got any video of it in action?
Looks like the line starting with "for watering" is part of the comment on the previous line. Copy it and paste it at the end of the line above, then delete the "for watering that is on it's own line. All you should have is the line below."const long interval = 60000; // Change value to change time to check for watering. 60000 = 1 minute"
Yes, it should work fine with either DHT11 or DHT22. You will probably need to adjust the code.
Nice tutorial. Do you need a magnifying glass or other magnifier to work with SMD parts?

If you are referring to the DHT11 library, make sure you have the library in the correct folder.If you are referring to the Arduino code, there is no variable called soil. Maybe post your code?

Sorry Michal but I don't measure sleep mode current. The ESP8266 is put to sleep and wakes up after 6 minutes, takes the readings and sends them to wunderground and Dweet. Then it goes back to sleep. It has been live for over a week and I haven't seen the battery level go below 82%. Mostly it stays around 92%.
Nice idea. I like your design. Are you going to share the 3D design?
ESP8266 Weather StationView Instructable »
Very nice. Now to find an estate sale.
Very nice job!
Interesting. Never had one die on me. I plan on building a weather station soon and may also use a BME280. Similar to a BMP280 but with humidity and more accurate, but also more expensive.

Thank you.I didn't really compare life expectancy of DHT22 vs DHTt11. I just went for which one was more accurate.

This economical sensor provides 2cm to 400cm of non-contact measurement functionality with a ranging accuracy that can reach up to 3mm. Each HC-SR04 module includes an ultrasonic transmitter, a receiver and a control circuit.
Great idea. Not hard to do. You could an mp3 shield and a small speaker.

I added a schematic. Great suggestion.
Yes, a picture of the back would be good too
Thanks for the great comment. Yes, a schematic would be good. Let me see what I can do.
