Vega Tilt Sensor

Compact, Dual-Axis Tilt Sensor for Industrial Applications

Aeron manufactures compact, industrial grade dual-axis digital tilt sensors for industrial inclination measurement. Built on the MEMS technology, Aeron Tilt Sensors run advanced statistical filtering and digital signal processing algorithms. This enhances the system performance to deliver precise angle data about both the axes (X- and Y-). Encased in a rugged IP65 enclosure, Aeron tilt sensors perform well in the harsh outdoor environment. These tilt sensors come with industrial grade connector and standard RS232/RS485 MODBUS interface.

Solar Tracking in Solar Power plant


Solar power is becoming the leading source of renewable energy due to their reliability and their viability with the solar panel costs coming down. To harness maximum power, the solar power plants must always maintain the inclination of the solar panel as per the position of the Sun to capture maximum radiation. This can be achieved by using a tilt sensor to track the Sun’s current position and give the feedback to the control system to adjust the incidence angle of the solar panel accordingly. Using optical sensors for solar tracking is not an all-season solution as weather conditions can limit their accuracy.


Aeron’s VEGA family tilt sensor, TS2D is a dual axis (Azimuth and Elevation) sensor that provides highly accurate real-time tilt angle information over a serial interface. TS2D is equipped with highly accurate MEMS based solid state accelerometers and gyroscopes to sense the absolute inertial angle of a platform. The TS2D design is complaint with industrial standards and provides output in all-weather conditions. TS2D integrated with Solar tracker system can be used for precise automated control of panel position helping to increase the energy yield. The angle precision has direct impact of the energy harnessing output. The tilt data is available at fast rates with high resolution making it suitable for real-time tracking applications.
