Solidago canadensis belongs to the genus Solidago L., which is S. canadensis L. (English: Canada Goldenrop) and S. decurrens Lour. (English: Common Goldenrop).
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!
