When I added 6 of these to my cart, I didn't see the discount price($19.90).

I'm using the sensor. The temperature seems ok, but RH is way off, showing 72% while my hair hygrometer is showing 45%. Have I got a bad copy?
I had far better results with the DHT11, but that sensor is not low power ...

is there a Fritzing file to download? im using this for a school project and am required to show wiring diagrams.

Hi
Please retry it, when you add 6 in cart, the price should be $19.90, if it's still not work, please contact our sales: [email protected]
