I am using the product in a weather station application for measuring relative humidity and atmospheric pressure, and so far it works well. The sensors are available via I2C bus using their default addresses. The RH sensor si7021 has its white protective film on, and it should not be removed, as the film protects the sensor. You will find the details in the si7021 datasheet. The pressure sensor BMP280 is a little more complicated to use, but the procedure is explained in the datasheet. Bosch has also published example code on Github: https://github.com/BoschSensortec/BMP280_driver I have one comment about the board layout: the clearance between the component leads and the hole for the screw is so small, that the screw might short-circuit the leads. So be careful if you use a metallic screw to secure the board, or use washers that are of insulating material.
