Just using a DS18B20 (Waterproof Version) with Arduino Uno. Getting readings on my Cayenne page well but the readings are slow i.e. I put sensor in hot water . Temperature showing by sensor increased from 25 deg C to 49 deg C within 4-5 second.
I get the sensor out from hot water. It tool more than 5 minutes to return back to 25 deg C by sensor. Whats the issue . I also wipes the sensor with cotton after getting it out from hot water.
Please help. If anyone can suggest any fast temperature sensor (water proof for outdoor) , please let me know.
