CJMCU-06 Pressure Sensor Help

Other Hardware Sensors
1

Hi Everyone,

I am working on building a vehicle gauge cluster, and one of the measurement parameters I wanted to include was altitude. I purchased CJMCU-06 pressure and temp sensor (which packages the SPL06-001), naively thinking it would would have a readily available Arduino library. Well, I was almost right.

As it appears, there is no library specifically for CJMCU-06 / SPL06-001, but there is a library for SPL06-007. The library appears to work to the extent that I can get coefficient and temperature readings from the sensor.

What I cannot get is reasonable pressure and altitude values, with the sensor/library returning negative values

  Serial.print("praw: ");
  Serial.println(get_praw());
  
  Serial.print("praw_sc: ");
  Serial.println(get_praw_sc(),3);

  Serial.print("pcomp: ");
  Serial.println(get_pcomp(),2);

  Serial.print("Measured Air Pressure: ");
  Serial.print(get_pressure(),2);
  Serial.println(" mb");

 praw: -4571852
 praw_sc: -0.581
 pcomp: -507417.53
 Measured Air Pressure: -5074.18 mb

I am guessing that the registers the library is reading are not quite the same between SPL06-001 and SPL06-007, and that's why I am getting wonky data.

Does anyone have any experience with this before I go digging through the library, or just chuck this board and buy something with better support?

The cause of the error may be in the another part of the code.
