The Indoor Beacon S1 is a high-performance solution featuring an ultra-low-power chipset and BLE 5.0 technology. The S1 consists of two parts: the sensor housing and the magnet. Equipped with double-sided adhesive tape on the back, the S1 can be attached to doors, windows, and even desk drawers to detect opening and closing remotely. As soon as the sensor detects that a door has been opened, it automatically sends a notification to the end-user app to alert the user. The door opening history can be viewed in the app at any time. The S1 is suitable for applications such as security monitoring, asset tracking, cold storage monitoring, inventory control, and more.
