The terminal reports events to the home fire alarm controller, enabling data statistics and alarm data collection. Data is transmitted via FosLink, ensuring high real-time performance. The module uses precise ADC sampling to achieve low battery alerts, real-time power measurement, and other features. The low-power communication module ensures the main unit has an ultra-low standby current of <30uA. It is suitable for applications in private homes, storage rooms, archives, water tanks, and other scenarios requiring water level detection.
