SSOC-A60 2-Axis analog sun sensor
€7,200
Sun Sensor on a Chip (SSoC), is based on MEMS fabrication processes to achieve highly integrated sensing structures at low cost for high accurate sun-tracking and positioning systems. SSOC-A60 device measures the incident angle of a sun ray in both azimuth and elevation. The high sensitivity is based on geometrical dimensions of the design.
Every sensor is characterized and a look-up table is provided for its application. It included an internal thermistor for temperature compensation. The use of a metal shield and a cover glass in the objective minimizes the ageing of the device under high energy particle radiation.
