Temperature
• Aslightairowof2mphormorewillspeeduptemperatureresponsetimes.
• DROP can be used to measure water or snow temperature by submerging the thermistor.
Humidity
• For accurate humidity readings, allow the DROP to equilibrate to its environment. Depending on the temperature and humidity
differentialbetweenenvironments,thiscantakebetween20and90minutes.
• After submersion in a liquid, humidity readings, if available on your DROP, will be impacted until the humidity sensor area has fully
dried. Gently blowing on the sensor area (the small grid of holes in the front case) can speed this process.
• Afterexposuretotemperaturesover80°C,anoffsetinhumiditymaybepresentforaperiod.
Connectivity
• Typicalrangeis100ftbutlongerrangescanbeachieved.Metalenclosures,ice,submersioninliquids,obstructedlines-of-siteand
ground level or non-vertical logging positions will reduce connection range.
• If more than 3-4 DROPs are present, turning off auto connect and manually connecting one at a time will help the app connect
successfully. Typically, a maximum of 8 DROPs can be connected to a device at a time.
• The DROP uses Bluetooth Low Energy (BLE) to connect to iOS devices. Android compatibility is coming soon.
Operating Temperature
• TheDROPwilloperatewithoutrestrictionfrom14°F/-10°Cto131°F/55°C.Operationatlowertemperatureswillbelimitedbythe
availablepowerandlifespanofthecoincellbattery.Downloadingafulldatalogintemperaturesbelow14°F/-10°Cmaytaxthe
batterytothepointwheretheDROPwillnotoperateuntilthebatteryhasbeenreplaced.Forbestresultsbelow14°F/-10°C,usea
freshbattery,keepdatalogdownloadsshort(1000datapointsorfewer),orallowtheDROPtowarmtoabove14°F/-10°Cbefore
connectingorattemptingtodownloadlogs.TheDROPcangenerallybeexpectedtocontinuetologdatapointsdownto0°F/-18°C
with these limitations.
Battery Life
• Coldconditions,frequentloggingrates,andfrequentlogdownloadswillallshortenbatterylife.
• Whendownloadingextremelylargedatalogsormakingrmwareupdates,avoidusinglowbatteriesandconditionsbelow32°F/0°C.
• EstimatedbatterylifeatthebaselinesettingsprogrammedintoyourDROPwhenshippedfromthefactory(10minloggingrate,5
secconnectionrate)androomtemperature(77°F/25°C)isabout4months.Intensiveloggingandconnectionsettings(2seclogging
rate, constant connection) can reduce battery life to as little as 11 days.
