# BluVib-P3

> Ultra-low-power wireless triaxial piezo vibration and temperature sensor with programmable sensitivity, 16 Mb onboard storage and up to 12,800 lines of resolution.

The Sensor-Works wireless tri-axial piezo vibration sensor is an ultra-low-power, battery-operated device that measures vibration and temperature on three axes. Built on three piezo accelerometers bonded to a stainless-steel base for maximum signal quality, it operates stand-alone or in a network and is user-programmable from interval wakeups through to near-continuous monitoring.
