The AED NB-IoT Module WAIOT-N includes the main unit and the IoT bridge, which can be installed in the AED cabinet, allowing users to remotely monitor the AEDs with NB-IoT technology. The main unit automatically identifies the different audio frequencies of AED's daily self-test results; when used with the IoT bridge, it can detect the opening and closing of the AED cabinet, whether the AED is in the cabinet, etc., and upload all the aforementioned status to a user-owned management system or WhaleTeq AIMS CMS – Cloud platform in real time. The WAIOT-N assists AED managers in keeping abreast of each AED equipment at any time and saves the time for personnel to on-site confirm the self-test status one by one. It’s ideal for application on a massive amount of widely distributed AEDs with effortless management.
