A Node-RED flow to implement sensor data logging to a USB drive connected to the Enterprise IIoT Gateway
Flow to check for a connected FAT32-formatted USB drive to the Enterprise IIoT Gateway's USB port
Flow to receive, filter and format the sensor data and saves it into CSV files
NCD Sensors Metadata:
- Time: The time at which the data was received and processed, in the format: HH:MM:ss
- Fimrware Version: The current firmware version on the sensor
- Transmission Counter: Represents the count of data transmissions emitted by the sensor (1-255).
- Battery Percentage: Represents the battery percentage of the sensor at the time the data transmission was made.
- RSSI (Optional): The received signal strength indicator measures the amount of power present in a radio signal. It is an approximate value for signal strength received
CSV Sensor Data Example (type 108):
msg.payload.sensor_data: Contains the field variables (depending on the type of sensor; pressure, temperature, humidity, vibration, current, etc.) emitted by the sensor.
