user53799: 
I am trying to get my DHT 11 from the official arduino store to work (https://store.arduino.cc/grove-temperature-humidity-sensor). 
I am following this guide right here:
http://wiki.seeedstudio.com/Grove-TemperatureAndHumidity_Sensor/
But I'm only getting invalid output of 0 humidity and 0 degrees. 
I hope the image helps in identifying my problem. 
On a side note, my sensor looks like a part is missing which is very strange and makes me doubt the right product was sent to me. 
Some more information:
- Black to GND
- Red to 5v
- White is wmpty
- Yellow to d2
- Using an arduino Uno
- Output does not change whether the sensor is actually connect or not. 
- Total noob at this. 
Help would be appreciated a lot! 


user30175: You haven't bought a DHT11 module but the Grove - Temperature&Humidity Sensor (High-Accuracy & Mini) / TH02 module.

Thus you should use the example code here or follow the guide at seedstudio wiki.
Datasheet of the sensor: https://www.silabs.com/documents/public/data-sheets/Si7005.pdf
