Hi
I have installed 1wire sensors in my ventilastion system to measure temperatures and make a heat recovery curve.
I'm using DS18B20.
When looking at these sensors online i found the following info:
OPERATION—MEASURING TEMPERATURE
The core functionality of the DS18B20 is its direct-to-digital temperature sensor. The resolution of the temperature sensor is user-configurable to 9, 10, 11, or 12 bits, corresponding to increments of 0.5°C, 0.25°C, 0.125°C, and 0.0625°C, respectively. The default resolution at power-up is 12-bit.
When I look at the temperatures measured by the LM i get 0,25-0,5C jumps when reading. Is it possible to get this reading more accurate? I would like to have 0.125 or 0.0625 options as well?
