  • How to use DS18B20 Temperature Sensor - Arduino Tutorial

    interesting prez, guy, You could add some infosinfo about "resolution", : Precision "9-10-11 or 12 bits" is ajustable on the DS18B20 (==> respected resolution then from 0.5 to 0.0625°C )the more precision you want, the "longer" it take for a reading (0.1 sec to 1 sec approx - though, 1 sec reading is pretty fast anyway, i can not see a project that could note live with that !)there is an IDE sketch (http://www.homautomation.org/2015/11/17/ds18b20-ho... for changing the precision through writing in the probe EEPROM, - so you have only to do it ONCE for all, it remembers after power lossand, for signal smoothing, you might think of using Exponential Moving Average, This is doing a fine job for a compact code and limited memory ressource (http://playg...
