What is a HOBO Data Logger? n A HOBO data logger is a small (matchbox size), inexpensive (under $100), battery-operated measuring device that can be put anywhere in our galaxy! HOBO's include a microprocessor, data storage, and a sensor; everything needed to quickly and easily take measurements.

What HOBOs Measure n n n n n air temperature water temperature matter (solid, liquid, and gas) temperature relative humidity Dew point temperature light vibration contact closure (open/closed) motor (on/off) AC sensors, and more

Who Can Use Them HOBO data loggers are simple for anyone to use n Currently used by students of elementary school as well as researchers. n

How Data is Retrieved n Data is easily retrieved from graphs on any computer with software
