Sun Direction Sensor

This can be as simple as some solar cells and shades or as complex as a steerable telescope depending on mission requirements.

Sun direction sensor.

A sun sensor is a device that senses the direction to the sun. Analog sensor whose output signal is a continuous function of sun angle. To test motor 1 set the steps to 200 the interval to 20ms and the direction to forward. Sun sensors are usually classified into three types.

However the main advantage of pinhole sensor is to work on two axes while the slit sensor is a sun pointing system working only in one direction. Its characteristics make it a suitable tool for high accurate sun tracking and positioning systems with low power consumption and high reliability. The sun tracking sensors were experimented in operative conditions with direct exposition to the sun. Sun sensors are used for attitude control solar array pointing gyro updating and fail safe recovery.

Field tests of the sun finder sensors. The high sensitivity reached is based on the geometrical dimensions of the design. Iss dx sun sensor measures the incident angle of a sun ray in both orthogonal axes and the solar radiation. An earth sensor is a device that senses the direction to earth.

You now have. Click on the run button and you should see motor 1 do one complete revolution in about 4 seconds. The sensor inputs since we want to be able to track the sun we need some form of light detector. Stepperbee are simple to use.
