nemi Log

Battery Powered Wireless Data Logger with Integrated Sensors

nemi Log is a stand-alone wireless data logger whose battery life is maximized using i4M's highly efficient nemi Link 2400 wireless technology.  It receives data from up to three wireless sensors and logs it on a micro SD card. With the integrated 9 DoF IMU, nemi Log can also be used independently to measure and monitor accelerations, rotation rates, rotation angles, and magnetic fields. The data logger nemi Log is particularly suitable for temporary offline applications, where the data can be read out from an SD card. Since it can be mounted very easily and flexibly, it is also often used in rotating and moving applications.

Detection of physical stresses on the human body in roller coasters

Using the acceleration sensor nemi G+ attached to a chest strap, we have determined the forces and accelerations that occur on the human body while riding roller coasters. With this knowledge, visitors with disabilities can also be offered an extended and improved use of roller coasters and attractions.


Safe measurement during active operation

Risk-free attachment to the body

High robustness against dynamic loads and weather influences

Solution & Adventages

Flexible assembly and disassembly

Uncomplicated handling thanks to completly wireless measurement technology

Longer measurement series because of long battery life
