    Not the most accurate

    posted by davet76 on 04/18/2013 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    Easy enough to wire up - the middle pin didnt appear to be labelled but S is signal and - is ground so the middle one must be power, I think it can take 3.3V or 5V in
    Cons:
    Poor accuracy at lower temperatures - seems to be reading about 5 degrees too high. Also I think the humidity might be out Ther...

    DHT11 Arduino Compatible Digital Temperature Humidity Sensor Module

    posted by Troncs on 03/22/2013 Certified Owner

    Involvement:General (knows how to use it) - Ownership:1 week to 1 month

    Pros:
    With only 3 wires: S_ignal, 5V and GND you can get infos which you can use to measure temp. and humidity. Price is very good and the sensor works fine. You can get the Temperature, % humidity and the Dew Point for the combination of Temperature and % Humidi...
    Cons:
    Not measure under 0 Celsius

    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:
    good product it works perfectly and is very cheap. I connect to Raspberry Pi without problem and now I can see temperature and humidity.
    Cons:
    You can find istruction on Adafruit to connect to raspberry pi and this item have the resistor 4,5k on the data pin so you can ...

    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:
    Cheap, easy to use, gives you temperature and humidity using only one dataline. I use it with Arduino + DHT11 library that can be found on the internet.
    Cons:
    Not very accurate, datasheet says +/- 2C. When I log temperature for a day, I see kind of spikes of 1-2C. I do not believe the ...

    Involvement:General (knows how to use it) - Ownership:1 day to 1 week

    Pros:
    Very good quality, you can know exactly what temprature and humidity is. You get very precise lavel of the megerment.
    Cons:
    I see no cons at all. May be just one - both of unit have slightly rotated position of blue mesh. It doesn't prevent unit from ...

    Involvement:General (knows how to use it) - Ownership:1 week to 1 month

    Pros:
    The sensor works fine. And the price it's very good. I can get the Temperature, % humidity and the Dew Point for the combination of Temperature and % Humidity. You can only need 3 wires: S=> signal, - => GND, 5V (central pin). There are a lot of exam...
    Cons:
    A little paper with a brief will be welcome. The sensor only get integer, for example: 22º Celcius, you can't get floats....

    Pros:
    Packaging was great. Device worked right out of the box with Arduino DHT11 libraries. Lots of fun to play with!
    Cons:
    This particular device can only be read every 2 seconds, but how much does the temperature and humidity change in 2 seconds? I...

    Pros:
    well built over all, solders are solid, pcb is good strong material, sensitive to 0-50 degrees and 0-90%HR are stated in the description, simple to use, good accuracy in room enviroment, included pull-up and simple one wire interface, This Temperature senso...
    Cons:
    The measures are of type INT, not FLOAT, but is not a really problem. The measure is very accurate.
