Bear in mind that all these diy chips are basically old stuff. This one dates from 2012. Obviously nothing wrong with them, they are still used in a lot … Read more

Continuing with the Barometric Pressure Sensor saga. Here are the data sheets for the MS5611, and the MS5607. The parts that show the different methods for calculating pressure and temperature are highlighted in the images. Use the linked datasheets if you can’t read the fine print. Crudely changing the code at least gives me good … Read more
