Abstract

The invention discloses a food deterioration detecting device with a voice broadcasting function. The food deterioration detecting device comprises a control module. The control module is respectively connected with a sensing module, a liquid crystal display module, a keyboard, a real-time clock module and a voice broadcasting module. The food deterioration detecting device has the advantages that the sensing module is used to detect the moisture, resistance and temperature of food, data offset can be well eliminated, temperature excursion and false detection can be reduced, the device is small in size, high in precision, good in stability, and the like, and the defect that a bacterial culture method for detecting the food is long in time and poor in portability is overcome; the device is multifunctional, can detect the resistance and moisture content of the food, and also has temperature measuring and timing functions; the measured data is digitally displayed through the liquid crystal display module accurately, and the device also provides the voice broadcasting function to allow elder people with poor eyesight to use the device conveniently.

Description

technical field [0001] The invention belongs to the technical field of electronic measuring equipment, and in particular relates to a voice broadcast device for food spoilage detection. Background technique [0002] In daily life, everyone hopes to buy and eat fresh food. Especially in summer, the fresh products people buy are easy to deteriorate and spoil. When people eat the food that has deteriorated, it will have a serious impact on human health. . Whether food is fresh or spoiled is usually identified from its surface gloss, elasticity, color, hardness and smell, but these are not enough. At present, in our country, the bacterial culture method is generally used to detect whether the food has deteriorated, and the conclusion of whether the food is edible can be made by measuring the content of a certain bacterial group in the food. However, this method requires 48 hours of laboratory analysis to make a conclusion, which takes a long time and is inefficient. Contents...
