Due to the northern climate and dietary habits, northerners are suitable for drinking semi-fermented and fermented teas. 1. Oolong tea Because the climate in the north is relatively dry and bitter cold, people are very susceptible to cold and hot, so they can't drink cold tea such as green tea. Instead, they should choose oolong tea. The oolong tea has a strong aroma and has the effect of Shengjin Runzao. When you have problems with internal dryness, you may wish to have a cup of fragrant oolong tea that will make you slightly sweaty and cool down. 2, Pu'er tea Pu'er cooked tea is mild, mellow, smooth, and full of aromas, just as the northerners are bold. Pu'er tea has the effect of solving tiredness and helping digestion. It can also warm up and warm the stomach. In the cold winter in the north, drinking a cup of Pu'er tea can both maintain health and warm the stomach. 3, Zhengshan black tea Zhengshan black tea is produced in Wuyishan City, Fujian Province. Although it is produced in the south, tea is very suitable for northerners. Zhengshan tea with a unique longan fragrance, tea soup was amber, taste mellow, with stomach, promote blood circulation and other effects, but also to supplement the body's trace elements.
New product of U85 micro laser distance sensors use highly focused class 2 laser to detect objects or measure distances, and can return a measured value via varieties intface( serial, usb, rs232, rs485, bluetooth etc.). The electronic distance sensor is a very small Laser Distance Sensor, but high resolution up to 1mm and long distance measuring sensor - teachable measuring range of up to 30m. Extremely accurate distance sensing sensors, errors down to ± 1mm. And the mini sensors and measurements support continuous measurement function, great for compact solutions(eg: robots) with the smallest Laser Distance Sensor of the world!
