Review on Onyehn Temperature Barometric Pressure Arduino by Fisseha Rodgers

I have found that they are a bit imprecise and devices are sometimes incompatible with each other. Under the same conditions and on trial, everyone was allowed to settle down before reading. Here is the data: Actual* 101896 Pa 19.3 degrees. C 3 m alternative block no. 1 102010 Pa 19.3 degrees from -57 m altitude. (this unit is the best) Block #2 102115 Pa 19.4 degrees. C -66 m alternative block #3 102283 Pa 19.8 degrees C -79 m alternative block #4 102284 Pa 19.6 degrees C -79 m alternative block #5 102063 Pa 19.1 degrees C -66 m alternative block #6 102712 Pa 20.8 degrees From -115 m altitude. (worst) Each device has independent calibration data, at least you can see different saved parameters. I will not use the 6th block and may make data or formula settings for others. The algorithms used correspond to the data sheet. * Using weather data for pressure, other temperature sensors +/- 0.5 degrees C and my location (on the coast)
