May 06, 2021· According to the datasheet I found, the sensor has a UART interface, so a level converter to 3V3 should be enough if you want to access just one these sensors. As the sensor uses a baud rate of 9600 you should use an Arduino that has a hardware serial interface to connect the sensor. So if you want to have your PC connected while reading the sensor, use a MegaXXXX model or a Leonardo.
