  • 14. Accelerometer A micro-machined device measuring static acceleration. Output voltage alternates according to 3 dimensional axis.
  • 15. Pressure A silicon sensor measuring absolute pressure. Output voltage can be converted to pressure by: פישבך קומה 13 פישבך קומה 1
  • 16. UV Sensor A “Schottky” photodiode for UV sensing. The sensor is brought to the surface of the box in order to efficiently absorb all UV rays. Max value in full UV exposure is 3.3. Shadow Through window Full sun light
  • 17. IR IR transmitter/receiver. Receiving function is checked using ISR due to high frequencies.
  • 18. Magnetic Sensor Measures the earths’ magnetic field. Nickel-iron strips change their voltage in presence of a magnetic field. Output voltage alternates according to 2 dimensional axis.
  • 19. Optic Sensor A CMOS optic sensor that decides on direction of movement by taking 1700 frames per second and comparing them. The sensor needs an external led and prism to work. Output voltage (“1”/”0”) needs to be processed in a state machine. 2 outputs for each direction.
