Does anyone know why some software libraries for the MH-X16 sensor use the command 0x9C to request the CO2 concentration while others use 0X86? Only the 0X86 (Read gas concentration) command is documented in the spec sheets. It looks like the 0x9C command gives you a three byte wide result whils the 0X86 gives you a two byte result along with the value of the internal Temperature sensor (looks like you have to subtract 40 from the Temp as well). I would like to get the value of the internal temp sensor as well as the CO2. Does anyone know where I can find more info on the 0X9C command? Thanks
