Hi there,
I am using thermometer with ATmega88 and two DS18B20 sensors in multi node bus.
The resolution is 0.1 °C and all work well except one unusual thing.
I found a difference between the two sensors, I explain:
There is a difference about two degres 2°C between them. Let's say Sensors_1 in point A and Sensor_2 in point B.
For example when sensors_1 say 28°C in point A and the sensor_2 in point B say 30°C, till this point, there is no problem, but if
I swap the two sensors the point A become 30°C and the point B become 28°C. I deduce that the problem comes from sensors.
The question is : How it is possible and do someone experince similar problem.
Thank's
