![]() bool hasAlarm() function returns true when the temperature exceeds either the high or low alarm set point.The acceptable temperature range is -55 to 125☌. setHighAlarmTemp() and setLowAlarmTemp() functions configure a device’s internal high and low temperature alarms in degrees Celsius.bool getWaitForConversion() function returns the value of the waitForConversion flag, which is useful when determining whether or not a temperature conversion is complete.setResolution() function sets the resolution of the DS18B20’s internal ADC to 9, 10, 11, or 12-bits, which correspond to 0.5☌, 0.25☌, 0.125☌, and 0.0625☌, respectively. ![]() There are many useful functions you can use with the DallasTemperature object. Arduino Nano V3.0 Vs Arduino Uno, Arduino Nano i2c LCD SHT20 Temperature & Humidity Sensor Arduino, measure atmospheric temperature. Other useful functions in the DallasTemperature.h library print(( char) 176) //shows degrees character
