I bought Gravity: Formaldehyde (HCHO) Sensor and succeeded to receive data from the sensor with Raspberry Pi 4.

However, the data is strange.

b'¥xff¥x17¥x04¥x00¥x00o¥x13¥x88¥xdb¥xff¥x17¥x04¥x00¥x00o¥x13¥x88¥xdb'

The fifth byte is like "x00o" , "x00p" , "x00s"

These are not byte data. Does anyone have idea what these data mean?
