Can I use the indoor data loggers outdoors?

No. These data loggers were manufactured for indoor use in non-condensing environments. Condensation will form from morning dew, temperature swings, fog, mist, and high relative humidity (RH). These data loggers are designed for indoor applications where the RH does not go above 95%.

If used outdoors unprotected, you will experience data loss and eventually damage the data logger. If placed outdoors, the data loggers need to be in a waterproof container with desiccant packs to absorb condensation that builds inside the case from temperature changes.

Please note that this will change the amount of time that the thermistor takes to register temperature changes.

Please note the light sensor on the H08-004-02 records from 2 to 600 lumens per sq ft, and the light sensor on the U12-012 records from 1 to 3000 lumens per sq ft. These data loggers are designed to measure indoor light levels only. Full sunlight is 10,000 lumens per sq ft.
