Gravity: Formaldehyde (HCHO) Sensor: The serial data is wrong
Account cancelled 2020-07-15 14:09:37 16168 Views4 Replies I bought Gravity: Formaldehyde (HCHO) Sensor and succeeded to receive data from the sensor with Raspberry Pi 4.
However, the data is strange.

The fifth byte is like "x00o" , "x00p" , "x00s"
These are not byte data. Does anyone have idea what these data mean?
However, the data is strange.

This is an Interesting Blog. Thanks for sharing.309330066 wrote: ↑Mon Jul 20, 2020 2:08 amHi,
Except for the fifth parameter is abnormal, everything else is normal.It seems to be "fused" with the previous one.Do you have any arduino main control board or MyGroundBiz Account USB to UART device to test this module？If not, can you send me the code for testing with Raspberry Pi.
