SUN SENSORS AND CONTROL SYSTEMS
Solar MEMS designs and develops sun sensors and control systems
We offers a wide range of sun sensors, called Industrial Sun Sensors (ISS), to measure the incident angle of a sunlight source and its radiation level. They are applicable for different applications: solar and light-source tracking, pointing systems, attitude control, sun radiation measurements, solar tracking platform controllers, and drones attitude determination.
ISSDX SUN SENSOR
Digital sensor
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.

Chracteristics:
- Two accuracy axes.
- Field of view from 10º to 120º (depending on the model).
- Accuracy from 0.005º to 0.06º (depending on the model).
- Position error (3sigma) less than 0.3º.
- It measures direct normal radiation (DNI).
