How many logs can I write to an SD card? You need to specify for example that one log file will include 24 hours (maximum length). You can make up to 10.000 log files. This means You can record up to 10.000 days = 27 years. Of course, You are limited by the size of the SD card = 32Gb. The size of each file depends on how many logs will be written each day. It may be 1 log a day or hundreds of logs a day. What are the limitations on archiving parameters (for graphing), how to calculate the maximum storage time depending on the number of parameters monitored? Sensor data is written to files as well as log messages. Up to 10 sensors. The maximum frequency of polling sensors is 1 time per second. For some sensors this is redundant - CAN sensors are updated 1 time in 10 seconds. |
