The world as it is, measured live.
Sense brings the measurements of places and machines into their twins: live, typed, signed and graded.
Sound, air, energy and occupancy, from what a building already measures.
SupportedState and readings from controllers and equipment, in their own units.
SupportedSmall devices fixed to a machine, a structure or a site take the measurements. Each reading is verified on arrival and attributed to the node that took it.
SupportedEvery reading with where it came from and how precise it is.
Supported
It never writes.
Sense has no way to send a command. Acting belongs to Pilot, and Pilot asks a person.
What was measured, said plainly.
Readings are kept apart from predictions.
A reading that fails its checks is not used.
A reading that cannot be traced to a node, or does not verify, stays out of calibration and out of every score.
The real world back into the model.
Verified readings calibrate a twin and test it against the real thing.
One unit for each quantity.
A measurement is named by its quantity, carries one unit and is checked against a range. A reading outside the range is refused, not clipped. Where a site states an uncertainty, it travels with the value as one standard deviation in the same unit.
Acceleration in metres per second squared, angular rate in radians per second, and vibration as a quantity of its own.
m/s², rad/sA unit quaternion from a sensor's own fusion of motion and gravity.
inferredMagnetic field, in µT.
µTPascals, 1,000 to 200,000.
PaDegrees Celsius, −100 to 1,000.
°CPercent relative, 0 to 100.
%RHGas resistance in ohms as a trend; index and gas equivalents from the sensor maker are kept as separate kinds and withheld while the sensor stabilises.
ΩPower in watts, current in amps, voltage in volts, energy in kilowatt hours.
W, A, V, kWhIlluminance in lux, liquid flow in litres per minute, air speed in metres per second, sound level in decibels. Audio itself never leaves the device.
lx, L/min, m/s, dBPosition of a joint, axis or body in radians or metres; velocity; torque in newton metres; force in newtons; a status code. The unit says which, and a band in one unit is never read in the other.
rad, m, N·m, N
Computed only where the number means something.
A derived signal is computed in the regime where it is valid and refused outside it. The result carries the lowest grade of its inputs.
From one acceleration triple, while gravity dominates.
°From at least eight acceleration triples, with the mean magnitude removed.
m/s²The norm of the angular-rate vector.
rad/sThe norm of the magnetic-field vector. A change from a site's baseline marks nearby motors, steel or current.
µTFrom temperature and humidity by the Magnus formula.
°CAgainst a stated reference pressure.
mOne torque times one angular velocity of the same shaft at the same instant.
W
Readings arrive from nodes and from the buses a site runs.
Signed nodes, six observe-only bus adapters and a Holoscan record sink feed the same interface. See the devices and the integrations.
