The HOBO U12 Logger can record Temperature, Relative Humidity, and Light with 12-bit resolution and can record up to 43,000 measurements or events. The external channel accepts a variety of sensors, including temperature, and split-core AC current sensors as well as 4-20 mA
Collecting data over an extended period of time is essential for tracking current performance of a building, space, or system to identify trends or anomalies. Data logging minimizes the need for operator involvement or interference. Some loggers can take readings for more than a year while others can even transmit logged data wirelessly, removing the need for regular physical data retrieval. IDL has various casings to allow logging in outdoor, wet, and extreme conditions.
