Anyone know of a great humidifier arduino project? my humidor doesnt keep the right humidity so I want to write a code with the DHT11 that gives feedback to a humidifier device to keep the humidity around 80degF and temperature around 80degF
The Surgeon General has determined that the consumption of tobacco products is harmful to health.
I suppose you mean 80% humidity.
If you want to keep your humidity levels within a few percent and/or want your sensor to work for longer than a few weeks get a proper humidity sensor, such as the BME280.
There are many examples of using the DHT11 as input. Google will find more than you can look at.
Try writing a sketch that reads the humidity and temp and prints them to the serial monitor.
You want to provide feedback to a humidifier. None of us know which humidifier you have or if it has any method for input. Do you?
Thank you vince and WV,
I do not have a humidifier yet, Looking for guidance from sucessful projects. Although, I do already have a DHT11 so I dont see my self upgrading to the BME280 quite yet. Maybe after I am successful then I will take the next steps to buying a BME 280
The DHT11 is a cheap and not particularly accurate humidity sensor. Especially inaccurate (and slow to recover) at high humidity. I would not waste my time with the DHT11. Your time would be better spent with the BME280.
The DHT11 may do as proof of concept - as long as you don't care of the humidity readings lagging reality (the sensor is slow, which is OK for atmospheric humidity which tends to change really slowly). But not for real deployment.
