The thermometer will work for at least 3 to 6 months with 2 AAA batteries (Not included), no more frequently battery changing needed. You also don’t need to buy glue or nails to help fix the thermometer if there’s metal nearby, the thermometer can be adsorbed on metal surfaces with the built-in magnet.
Hold data for 20 days if the sampling interval is 1min, and the max date storage is 30000 points. Different sampling interval can be setting.(10s/ 30s/ 1min/ 2mins/ 5mins/ 10mins/ 30mins) The saving data time will be different if you choose different sampling interval.
