A Tea Brewing Service Device with the Added Value of Increasing Tea Drinking Quality in Our Leisure Life

This study proposes a loose-leaf tea brewing service device with the added value of increasing tea drinking quality in our leisure life. The proposed device with multi-infusion timing control and user friendly interface characteristics utilizes AT89S51 programmable microcontroller to detect the input signals and trigger the corresponding outputs. The input signals come from a power switch for turning the controller on/off, three push buttons for setting the brewing time, and two other push buttons for controlling initial/extra brewing time setting and start/stop time control. The corresponding outputs include a power LED for indicating whether the controller is working or nonworking, a buzzer for reminding the completion of timing, and three 7-segment displays for showing the remaining time. Conclusively, the proposed microcontroller-based tea brewing service device can remind users remembering pour the water out timely, allow users to reset brewing time based on personal favorite tastes, and allow users to make the second or third rounds of tea infusion time for each individual setting. Therefore, the tea taste quality can be guaranteed. [Sung-Tsun Shih, Chin-Ming Hsu, Chian-Yi Chao.
