High_Accuracy_Dual_Axis_Inclinometer_Sensor__Arduino_Gadgeteer_Compatible___SKU_TOY0048

Introduction

This gradienter module is based on the SCA100T-D2 chip, which provides instrumentation grade performance for leveling applications.The measuring axis of the sensing elements are parallel to the mounting plane and orthogonal to each other. Benefiting from its low temperature dependency, high resolution and low noise, together a with robust sensing element design, the SCA100T the ideal choice for leveling instruments.
