Application Notes 1 Using the magnet You must orient the magnet to the case correctly for the HOBO State data logger to detect it When the a eo HOBO State sees the magnet it will blink its green te FA State LED light When it cannot see the magnet it will a onset blink its red LED light The recommended orienta tion Diagram A along with some that will not work Diagram A Diagram B are shown in the drawings at the right Diagram B A simple application door monitor Mount the magnet on the door using its two sided foam tape Use Onset s software to launch the logger then mount the HOBO State data logger on the door jam using the hook and loop strip The magnet will need to be less than 1 4 inch from the logger case when the door is closed and over 3 4 inch away when the door is open Make sure that the logger blinks green when the door is closed and red after it has been opened The logger will record the times when the door is either closed or opened The hook and loop tape allows you to conveniently remove and replace the logger for readout A door in a house with small children living in it recorded over one thousand state changes during a one wekk period in the summer 2 Measuring contact closures The HOBO State can be used to measure contact closures Connect the contacts to the black and white wires on the contact closure cable The polarity o

4. f this connection does not matter The red wire is not connected on the HOBO State data logger Using the external contact closure input allows the logger to be mounted remotely from the contact Make sure that no external voltage is applied to the contacts When measuring contact closures the contacts should not be connected to anything dse even ground 3 Measuring the presence of positive DC voltages Put a diode in series with the white wire on the external contact dosure cable The diode will block the positive input Note it is critical that you connect the diode with the polarity shown in Diagram C This will only work if the input voltage is ground when the positive voltage is not applied Never apply a negative voltage to this input the diode will not block it Make sure you use a diode that has a breakdown voltage high enough to block the positive voltage you intend to apply In no case should you use this technique to connect the logger to any AC voltage or a DC voltage above 15 volts input voltage Diagram C Detailed Specifications Minimum state duration 1 2 second Time Accuracy 100 ppm at 20 C full dependence shown in Plot A Capacity 2 000 state changes requires 8K of memory in HOBO Shuttle to fully offload External contact input relay switch or contact closure Length of included external contact cable 6 Operating temperature 20 C to 70 C 4 F to 158 F Relative humidity range 0 to 95 non condens

7. tate data loggers work well when there are only two values to measure i e open or closed on or off The HOBO State data logger records the time at which a state change occurs with a resolution of half a second and records nothing between these changes If you wanted to do this with a logger that uses preset intervals you would have to set it to 1 2 second intervals and an 8K logger would run out of memory in about an hour The HOBO State data logger checks for the contact closure every half of a second and can record 2000 state changes I ts time out in the field is limited by the battery about one year No data is information too The HOBO State logger records the initial state and a final state at readout even if the state has not changed This allows you to determine the entire period during which the HOBO State was watching for state changes
