The invention discloses a cooking utensil. A weight sensor is arranged in a casing below an inner pot, a telescopic rod extending toward the inner pot is arranged on a pot cover, an insulating detection plate is fixed at the end of the telescopic rod, and a Two conductive contacts. The method of cooking rice after using the above-mentioned cooking utensils for automatic identification of rice types is as follows: measure the weight of the inner pot when it is empty and the length of the insulation detection plate at the end of the telescopic support rod when it touches the bottom, and then measure the amount of dry rice grains in the inner pot and fill it with water. After the rice grains are submerged, the weight of the liner and the length of the telescopic strut when it touches the surface of the rice grains are calculated based on the quality and height difference before and after the rice is filled with water, combined with the cross-sectional area of ​​the liner and the density of water to calculate the density of the rice and compare it with the database. After getting the type of rice, pour in an appropriate amount of water. The advantages of the present invention are: the method of identifying rice grains by density has higher reliability and accuracy, and the method of controlling the amount of water added by contacting and conducting with two conductive contacts to form a closed loop is accurate and timely.

The invention discloses a smart flowerpot and a water potential and weight based control method. The smart flowerpot comprises a closed air bag, a temperature and humidity sensor, a weight sensor, a water supply device, a communication module, a single-chip microcomputer, a flowerpot body and a plant. By means of the technology of Internet of Things, a terminal of the communication module can control and manage growth conditions of the plant at any time anywhere; water potential of leaves can be calculated by temperature and humidity and can judge whether the plant is short of water or not, whether the plant is short of water or not can be monitored in real time, and lagging in monitoring is overcome. In addition, by the water potential and weight based control method, watering of the plant can be accurately controlled so as to prevent too much or too less water.
