# LSN50 in the stop mode mode the Vcc is about 3.3v, and the runtime is 3v.Because the sensor length is 50cm, in order to achieve the accuracy to the mm, PA0 is 1.5v and the sensor length is 50cm.1.5v/ 5000 = 3mv/ 1mm, which means 3mv stands for 1mm. | # LSN50 in the stop mode mode the Vcc is about 3.3v, and the runtime is 3v.Because the sensor length is 50cm, in order to achieve the accuracy to the mm, PA0 is 1.5v and the sensor length is 50cm.1.5v/ 5000 = 3mv/ 1mm, which means 3mv stands for 1mm. |
