Typical Applications

IMU90 Inertial Measurement Unit is a high performance 6 DoF MEMS-based inertial sensors, which has been widely used in the following fields:

- Unmanned Aircraft and ROVs                         - Smart Agriculture

- Robotics Control                                              - AGV


IMU90 Inertial Measurement Unit widely used in Unmanned Aircraft

UAV is unmanned aerial vehicle, commonly known as a drone, is an aircraft without a human pilot aboard. The flight of UAVs may operate with various degrees of autonomy: either under remote control by a human operator or autonomously by onboard computers.
SkyMEMS IMU90 Inertial Measurement Unit is an industrial level IMU module, it can provide continuous acceleration and gyro angle for the UAV, which has been widely used in small UAV flight control.


IMU90 Inertial Measurement Unit widely used in smart agriculture

Smart agriculture has changed the way farmers work their land. Real-time location information also allows farmers to maximize field utilization by avoiding missed or overlapping planting and harvesting efforts while minimizing time and fuel usage through optimized travel. Such systems can also provide semi-autonomous piloting of farm machinery to reduce driver fatigue and allow efficient operation even in low visibility conditions such as dust, fog, rain, and darkness. Currently more than 50% of farmland, great and small in extent, now utilizes smart agriculture methods with adoption continually increasing.

Because they can accurately measure the movement of objects in three dimensions, IMU modules are essential to modern society. They are utilized in many more applications than just the automatic control and autonomous driving on tractors and other agricultural machinery used for precision agriculture. Examples include orientation measurement during autonomous driving, drone orientation control, camera and antenna vibration detection and control, and controlling the angle and attitude of blades and arms on construction and mining equipment. The high-precision detection of tiny changes in movement, which are too small for the human eye to detect, makes IMUs vital to high-precision data measurement and control of machinery.

SkyMEMS's IMU modules use high-performance MEMS sensors that features excellent stability, low power consumption and low noise characteristics.. And their linearity characteristics enable high-precision measurement of various kinds of movement over a wide range from slow to fast. This allows them to be used in a broad array of smart agriculture applications.
