nemi Log (+ cellular)

Battery Powered Wireless Data Logger with Integrated Sensors and cellular option

nemi Log is a stand-alone wireless data logger whose battery life is maximized using the highly efficient nemi Link 2400 wireless technology.  It receives data from up to eight wireless sensor nodes. With the integrated 9 DoF IMU and GPS, nemi Log can also be used independently to measure accelerations, rotation rates, rotation angles and magnetic fields and determine the position.
In the nemi Log basic version, the data is stored on a micro SD card. As the data needs to be read out from this SD card, in this version nemi Log is particularly suitable for temporary offline applications. Since it can be mounted very easily and flexibly, it is also often used in rotating and moving applications.
The nemi Log + cellular version offers the option of sending status messages via MQTT and uploading data to an FTP server via cellular radio. This offers considerable advantages, especially in construction monitoring, because not only medium-term measurements with high sampling rates are possible, but also long-term measurements at low sampling rates.

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
