Review on Onyehn Temperature Barometric Pressure Arduino by Sean Burnett

I found them to be somewhat inaccurate and some of the devices were incompatible. 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)
