Control the heater or let it powered 24x7 ? #1

Closed Kinick4 closed 5 years ago

Kinick4 commented 5 years ago

Hi! First of all: Thanks for doing this! My readings were primary temperature. I will test your library later on today, but it seems to be the best one you can find on the net.

But I have on question: Do I really need to control the heater or can I power it 24/7?

Best regards Niklas

Hi, The control of the heater is done only the time required to get consistent values from the sensor. The method begin() is starting the heater for the time required, capture the value and stop the heater. You can power it 24/7 but to do that, you should extend the class and use the protected methods startHeater(), readRs() and stopHeater(). KR, Olivier
