I have a seemingly simple problem but I haven't found a solution yet. I recently got a DHT22 temp/humidity sensor and I wired it according to the guide from Adafruit.
I downloaded and installed the library. I loaded the "DHTtester" example sketch. I also included the Adafruit Unified Sensor library to be safe, because the guide said I might need to. But when I upload the sketch and check the serial monitor the humidity value is always "1.00%". The temperature also seems to be off by about 4 degrees F.
I don't know what is going wrong here. I've removed the 10K resistor but nothing changed. Does anyone know why this might be happening? Any help would be appreciated. Thanks!
