  • As the RF microwave sensor module which uses the Doppler Radar Principal which it develops at the domestic beginning patent it made an application. (The patent number : 0472880)

Use of Microwave Motion Sensor
  • traffic / express highway watch and control.
  • security relation products (sensor and alarm set etc).
  • automobile rear collision warning.
  • automatic door activation.
  • sensor light.
  • sensors applies in all products which operate.

Additional Information

  • Microwave Motion Sensor Module is developed applying Doppler Radar principle.
  • The role of Sensor Module is transmitting a low power Microwave from transmitting antenna and receiving the microwave energy reflected by objects to receiving antenna.
  • If the movement of the object is detected by the microwave motion sensor, the reflected microwave frequency is shifted away from the transmit frequency to receiving antenna.
  • The reflected and shifted microwave frequency is mixed with the transmit microwave frequency and results a low frequency voltage at the output of the sensor.
  • The Microwave Motion Sensor Module is designed with Dielectric Resonator Oscillator(DRO).
