DHT11 checksum error

Whenever I connect the temperature sensor to my Arduino I keep getting a checksum error. All of my wires are connected correctly and i am using the sample code provided.

In almost every case when you get a checksum error repeatedly it means that you have either bad connectivity, or a problem with your power rail. Try either using the appropriate headers like on the Versalino Sense & Move load board, wiggling it on the breadboard, or using alligator clamps on the pins to make sure it isn’t your wires.

If you still have trouble don’t hesitate to contact me so that I can help you get it working.
