Avoid the unexpected by adopting Quectel feature for sudden module power loss
2024-07-31
Shifting habits in power generation and consumption are causing instability in power grids in several markets, leading to an increase in brownouts, supply interruptions, and blackouts. This instability largely stems from remote work habits, the proliferation of renewable energy sources such as solar and wind, which allows homeowners to sell generated power back to the grid, and the rise in electric vehicle usage, which demands significant power for charging.
For IoT devices connected to less dependable grids or battery-powered devices that deplete their charge, unexpected power outages can have serious consequences. Sudden power losses often result in data loss and file system damage, as proper shutdown procedures, which ensure data integrity and system readiness for power down, cannot be completed in a timely manner.
To tackle this challenge, Quectel has introduced a feature that reduces power downtime to less than 100ms, preventing file system corruption. This feature is especially useful in scenarios prone to sudden power loss. For instance, if the module detects a falling motion, it will finish accessing the current data, halt new data writes to the file system, and then shut off the power supply. In such cases, the corresponding feature pin will be activated, and the module will power off within 100ms, significantly reducing the risk of data loss.
