+TIP: If you add Wifi and NTP the logged entry with show real world time stamps. If you don't have Wifi/NTP it will show the number of seconds since the firmware was booted up as a fallback without valid time.
+In this example we've set it up with a check to see if the SD Card is available, and then schedule it to log the sensor value every 5 seconds. \\
