    Fair price

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

    Pros:
    This sensor gives you a accuracy of +-2ºC and +-5RH for humidity, which fair enough for several projects. My first atmospheric logger worked just fine. Now I have updated with the DHT22.
    Cons:
    You cannot rely too much on the data collected from this sensor. It has a very low accuracy for humidity and temperature. For c...

    easy to use - very good for learning

    posted by Bergerrob72 on 06/16/2013 Certified Owner

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

    Pros:
    The price is good. The module sits nicely on a breadboard and is easy to connect to your Arduino. Build is strong enough and soldering is well made. Accuracy matches my other thermometers and electronic thermostats in the house as well as the humidity readi...
    Cons:
    Probably not suited for projects where accuracy is critical. Does not have decimal readings, only integer increments. Could be ...

    It is okay but no the most accurate.

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:
    It is really easy to use. Only has 3 wires: Signal, 5V and Ground (GND) and you can measure temperature and humidity. Price is very good and the sensor works fine. You can find lot of examples on internet. Just attach to Arduino, download the library and st...
    Cons:
    You can't measure temperature under 0 Celsius and the accuracy it not very well. Other sensors as a LM35 is better. For measure...

    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...

    good quality

    posted by hidaba on 03/03/2013 Certified Owner

    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 ...

    Accuracy is not great

    posted by wout8b on 03/02/2013 Certified Owner

    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 ...

    Perfect temperature and humidity sensor

    posted by dariod10 on 02/21/2013 Certified Owner

    Involvement:Expert (understands the inner workings) - 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 % Humid...
    Cons:
    Not measure under 0 Celsius

    Very precise working unit

    posted by f11lbert on 01/29/2013 Certified Owner

    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 ...
