Motor on/off with AC-field sensor (H06-004-02)
Magnetic field threshold: ~2 Gauss at 60 Hz. The logger will typically
work with AC motors drawing 1 amp or more. Mount it on or close to
the motor housing or to one phase of the power line to the equipment
being monitored.

AC-field sensor for mounting on motors (Part # H06-004-02)
The logger must be mounted very close to (ideally directly on) the field
source, as magnetic field intensities fall off rapidly with increasing distance
from their source (motor, transformer, or even a single wire carrying a large
AC current). While this may make it less convenient to attach the logger, it
means that interference from other sources is less likely.
he HOBO H6 loggers record On/Off
or Open/Closed status changes, storing
time, date, and state information for each
change. Use your PC to readout and
analyze the data or readout and relaunch

Motor on/off with vibration sensor (H06-003-02)
Vibration threshold: adjustable ~0.05 G to 0.5 G at 60 Hz
(.0001 to .001” displacement).
Angular response: the logger is sensitive to that part of the
vibration that is perpendicular to the logger’s face.
Light on/off (H06-002-02)
Light threshold adjustment range: approximately 10 to 100 lumens/m2
(fluorescent light). Its sensitivity to incandescent light is about ten
times greater.

Size/Weight: 60 x 48 x 19 mm
(2.4 x 1.9 x 0.8”); approx. 29 grams (1oz.)
Angular response: the logger is sensitive to that part of the AC
field that is perpendicular to the logger’s face.
Vibration sensor for convenient mounting (Part # H06-003-02)
A vibration is only weakly dampened by distance, so that the logger need
not be mounted directly on the source. However, this leads to the potential
of interference from other sources. The logger’s threshold adjustment can
be used to help discriminate against other sources.
The vibration sensor will reliably detect vibrations greater than 0.05G
which is roughly equivalent to the vibration produced by a household air
conditioner when it is on. This logger will not work if the vibration is too
small, such as the vibration from a household refrigerator.
The light intensity threshold monitored is adjustable from approximately
10 to 100 lumens. The HOBO’s light sensitivity is peaked in the forward
direction and can be taken advantage of to minimize the effect of other
light sources when trying to determine the on/off state of a particular
light source.
Monitors when doors are open/closed using an internal magnetic reed
switch and external magnet. External input cable included to monitor
contact closures of remote devices or presence of positive DC voltages.
Open/closed, contact closure (HOBO State, H06-001-02)
Two inputs: a magnetic sensor mounted in the logger detects when
doors are opened and closed (external magnet included). An external
input cable detects contact closures.
Spacing between HOBO State and external magnet: closed ≤ 1/4”;
open ≥ 3/4”
External contact input: passive relay switch or contact closure.
