Automated Pressure Release Mechanism for Conventional Kitchen Pressure Cookers

The process of releasing pressure in conventional kitchen pressure cookers is becoming unsafe due to failures in the safety nozzle and blockages in the pressure path. In this paper, a low-cost real-time pressure release mechanism is designed for enhanced safety and accuracy of cooking. This procedure is automated Arduino technology. The temperature sensor placed at the safety nozzle of the pressure cooker senses the temperature. It monitors the internal temperature continuously as an indirect measure of pressure inside the cooker. When the temperature goes beyond a set threshold indicating that pressure has reached optimal levels the Arduino Nano acts by activating a servo motor. The motor replaces the manual whistle, opening a valve to allow free steam release. If the temperature reaches the threshold, the LED will glow red instead of green. By automating the release mechanism, the system avoids constant monitoring or whistles counting, enhancing user convenience and safety. The System response time is within 3-5 seconds of threshold breach in all five experimental trials conducted. This paper demonstrates how the combination of real-time sensing and actuation can change our ordinary appliances and pave the way for future intelligent kitchen solutions.
