I am working on a 3D printed wind tunnel and I have designed a Pitot-Prandtl tube to measure the speed with two pressure sensors. I am using one BMP180 to measure the dynamic pressure and the other for static pressure.
I have done some research and I found out that I can't use two BMP180 sensors on the same SCL and SDA ports because they have the same IP. One way around it is to use a multiplexer but I don't have one and I want to create a second I2C bus on a free pair of pins using SoftI2CMaster library and I can't find any information on how this should be done.
I have no experience with Arduino and so far I managed to program one sensor and retrieve information from it. Can someone tell me where I can find information that will help me?
