Hi Blue Robotics team,
I’ve started to make a Raspberry Pi 3 IMU using the Adafruit sense hat. (great bit of kit!). My technical question is, my USBL software requires pitch and roll data to be displayed in -90 to +90 format, while the sense hat IMU is referenced from 0 to 360 for its output. Can any one suggest a Node red - node, where I could do the function to normalize the sense hat output so my software is happy. All the remaining inputs are done, gps compass ect.
I am trying to help a friend track and survey reference, the destruction of a local reef by crown of thorn starfish on the Great Barrier Reef. I’m planning to put a clump weight on my old second hand responder and mark a gps position on a map. The IMU will increase the position accuracy, fingers crossed it can reduce pitch and roll errors from the boat.
Thanks for your help - Mick
