Oh, under the banner of selling technology, it is actually mainly a problem of supply and demand. The demand has not reached the amount of daily consumables, there are few suppliers, and there is no large-scale production. For example, now TVs and computers only cost a few thousand yuan. Compared with sensors, I feel that the technology is much more complicated. Oh, the production of TVs and computers has formed a large scale, the overall cost has come down, and the market demand is huge, so the prices have come down on their own. , On the contrary, in the sensor industry, it is difficult for prices to come down.
