Pi Pico based environment sensor with Rotronic HC2A and BMP390

My attempt to make a metrology grade environment sensor. I found that cheap humidity sensors are not worth using as they drift too much when exposed to condensing atmospheres, so I am using an expensive temperature / humidity sensor. For atmospheric pressure I use 4 x BMP390 sensor modules and an algorithm to get the best performance. Time will tell how stable it is. As far as the service received from PCBway - excellent as always.
