NEMOSENSE device overview
NEMOSENSE-3xMEMS-ACC is a low-power IoT device with an integrated triaxial MEMS accelerometer. It acquires the data and stores it on an internal SD card. Data is stored in CSV file format and transmitted to the server, using the MQTT protocol, when the connection is available.
Analog-to-digital conversion is done on the device with the onboard ADC converter. This eliminates any noise picked up in analog cabling.
The onboard microprocessor is used to perform simple processing tasks such as FFT and basic statistics (Min, Max, Average, RMS). This eliminates the need for an expensive external computer.
