Solar MEMSModel ISS-DX - Digital Sensor for Solar Trackers

SHARE

ISS-DX sun sensor measures the incident angle of a sun ray in both orthogonal axes and the solar radiation. The high sensitivity reached is based on the geometrical dimensions of the design. Its characteristics make it a suitable tool for high accurate sun-tracking and positioning systems, with low power consumption and high reliability. ISS-DX sun sensor has been designed with a unique and novel own technology based on MEMS fabrication processes to achieve high integrated sensing structures at low cost.
