I have been using a MPU6050 from Invensense attached to trees and bamboo plants to measure the sway movement of these objects. But untill now this sensor seems to be more suitable for strong winds. I am looking for a sensor that can detect even the smallest movements like a light breeze that makes the plant or tree move slightly from left to right. I've been looking at the ADXL355 or ADXL313 or maybe even a tilt sensor? the requirements are small size and high resolution to measure small movements. Do you have any suggestions for me?
