N+Motion vs Vibration Meter, seismograph

Making real motion digital, and digital motion real. For fitness, logistics, vibration analysis, and gaming, motion is only as good as it is useful. NODE+motion measures nine degrees of motion with a 9DOF IMU, which allows NODE+ to accurately measure its orientation and movement. This is made possible through the combination of a three-axis gyroscope, a three-axis accelerometer, and a three-axis magnetometer. The magic is in the module. With a 3-axis accelerometer: up to +/-8g range, 0.061mg resolution, 3-axis magnetometer: up to +/-8 gauss range, 0.04 milli-gauss resolution, 3-axis gyroscope: up to +/-2000 degrees-per-sec, 0.061 degrees-per-sec resolution, and 9-degrees-of-freedom orientation engine, NODE+motion makes sensing movement truly mobile. + This application requires an iPhone 4s (or newer) or an iPad 3 (or newer), or an iPad Mini, and a NODE sensor device. About NODE: At Variable, Inc. we make sensory platforms that connect apps and smart devices to the real world, in new ways. NODE is a handheld, wireless, sensor platform that is transforming how we gather, process and use sensory data from the world around us. Combining advanced motion-sensing technology with interchangeable sensor modules to stream real-time information to any smart device.

Vibration meter is an app called seismograph or seismometer, which measures the strength of vibration, quakes, earthquakes, vibrations of the human body or any other objects around you. Our app allows for detecting and recording of seismic waves generated by earthquakes, volcanic eruptions, avalanches and other sources of vibration and shocks. Accelerometer in your mobile phone is used for detection of vibrations and measurement analysis. Graph presents a record of the ground motion at a measuring point. Ground movement or an object is presented as a function of time in the three Cartesian axes, with the z axis perpendicular to the Earth's surface and the x- and y- axes parallel to the surface. Mercalli intensity scale is a seismic scale used for measuring the intensity of an earthquake. It measures the effects of an earthquake and it is distinct from the moment of magnitude. Richter Scale assigns a magnitude number to quantify the energy released by an earthquake. Peak Ground Acceleration (PGA) is equal to the maximum ground acceleration that occurred during earthquake shaking at location. PGA is equal to the amplitude of the largest absolute acceleration recorded on an accelerogram at a site during a particular earthquake. In this app we use Instrumental Intensity Scale (developed by The United States Geological Survey) which maps peak ground acceleration and peak ground velocity on an intensity scale similar to the felt Mercalli Scale. These values are used to create shake maps by seismologists on around the world. Mercalli Intensity Scale distinguishes the following levels of vibration and impact damage: I. Instrumental - Not felt. Recorded by seismographs. II. Weak - Felt only on top floors of high buildings. III. Slight - Felt indoors, like a passing light truck. IV. Moderate - Windows, doors rattle. Like passing train. V. Rather Strong - Felt by all. Small objects upset. VI. Strong - Books off shelves. Trees shake. Damage. VII. Very Strong - Difficult to stand. Buildings damaged. VIII. Destructive - Significant damage. Trees broken. IX. Violent - General panic. Serious damage. Cracks. X. Intense - Most buildings destroyed. Rails bent. XI. Extreme - Rails bent greatly. Pipelines destroyed. XII. Catastrophic - Near total damage. This app allows you monitor and share the results of your measurements with other users. Measure and monitor all vibration and shocks using smartphone or tablet!
