# LSN50 in the stop mode mode the Vcc is about <span CLASS=bluetext>3.3v</span>, and the runtime is <span CLASS=bluetext>3v</span>.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.<span CLASS=redtext>1.5v/ 5000 = 3mv/ 1mm</span>, which means 3mv stands for 1mm. | # LSN50 in the stop mode mode the Vcc is about <span CLASS=bluetext>3.3v</span>, and the runtime is <span CLASS=bluetext>3v</span>.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.<span CLASS=redtext>1.5v/ 5000 = 3mv/ 1mm</span>, which means 3mv stands for 1mm. |
