This sensor measures temperature and RH and is designed to work with the HOBOnet Wireless
Sensor Network in which data is transmitted wirelessly from the sensor mote across the
network to the station and then uploaded to HOBOlink® web‐based software. With HOBOlink,
you can monitor sensor readings, view graphs, set up alarms, download data, and more.
