Three-Axis Level with WiFi Connection

Abstract

The Three-Axial Level (TAL) device measures the angular inclination around the three axes of the orthogonal system. It consists of a tripleaxis magnetometer sensor with I2C transmission and a NodeMCU V3 development board with WiFi module integrated. The device processes data from sensor, displays it on its screen and also transmits the angular values to various PADs (Portable Access Device). The experimental testing confirmed the initial expectation, showing the properly on-site operation of the designed device. This device is useful in the supervising process to avoid perturbing the worker that performs the leveling operation or when the working place is hard to reach.
