Abstract: A whistle detection device (100) for a pressure cooker. The device (100) includes microcontroller unit (MCU) (120), multi-modal sensing unit (102) with pressure sensor (106) and acoustic sensor (110) adjacent to a whistle outlet, signal processing unit (112), validation and counting unit (114), time monitoring and fault detection unit (116), and alert unit (118). The signal processing unit (112) generates a validated whistle signal upon concurrent detection of pressure signals and acoustic signals within a predefined time window. The validation and counting unit (114) increment a whistle count per validated whistle signal. The time monitoring and fault detection unit (116) determines a fault condition upon timing exceeding a predefined range. The MCU (120) activates the alert unit (118) upon whistle count reaching a preset threshold or fault condition.
