The U30 Wi-Fi is a weatherproof data logger with inputs for up to 5 Onset smart sensors. It is similar to the HOBO Weather Station Data Logger U30-NRC but provides web-based data access via Wi-Fi communication. This data logger has a storage capacity of 512 Kb and can log at user-specified intervals of 1 second to 18 hours. Depending on the sensor types connected and the sampling interval, the logger can be run with its rechargeable battery for several months. Beyond this duration, external power is required. It has a normal operating range of -20 to 40 °C (-4 to 104 °F) and can withstand an extended temperature range of -40 to 60 °C (-40 to 140 °F) although operation at these more extreme temperatures will decrease battery life.
The free software HOBOlink is required for configuring and launching the U30 WiFi and also for monitoring the station status and viewing/downloading data. A data plan is also be required for remote data access.
