Sampling rate of sensors


I have a few DS18b20 temperature sensors working but I dont know how often they sample the temperature.
Can the rate be adjusted as i dont need to know evry few milliseconds…
Alos this would reduce the amount of data being uploaded .


which device are you using raspberry pi or arduino?


Its Raspberry pi


i guess you are using the pi agent, you can rather use the and send data at your own time interval.
For pi agent you will have to follow the installation guide here and install a new device. then navigate to and change the REFRESH_FREQUENCY. currently it is set to 15 seconds.
a better option is use python library as it gives more freedom.
