[FAQ]erich.spindler asked about Grove - Carbon Dioxide Sensor(MH-Z16)

Hi, my name is Eric,I want to use the CO2 Sensor with an Arduino Mega board and the Grove Base Shield V2.The Mega has 5V Logic, so I'm putting the voltage switch on the base shield to 5V.But according to the Data sheet of the Sensor, the UART interface of the sensor can only take voltages from 0-3.3 V.Will the sensor be damaged by the 5V logic of the Mega Board?Regards,Eric
