Microwave Sensor

Microwave Sensor

The microwave sensor, also known as the microwave radar, is an instrument made based on the Doppler principle of electromagnetic waves.

Any wave has the characteristic of reflection. When a wave of a certain frequency encounters an obstacle, a portion of it will be reflected back. If the obstacle is stationary, the wavelength of the reflected wave is constant. If the obstacle is moving towards the wave source, the wavelength of the reflected wave is shorter than that of the wave source. If the obstacle is moving away from the wave source, The wavelength of the reflected wave is longer than that of the wave source. A change in wavelength means a change in frequency.

Microwave sensors are often used on automatic doors.

M-204G/204GD, (Unidirectional) Microwave Motion Sensor, is based on microwave technology, as a motion sensor for automatic door access system, installation height is 4 meters, detection range is about 5*3 meters.

M-703, Multi-purpose Microwave Motion Sensor, it features the low speed and lateral suppression functions.

Low Speed: When the movement speed is too slow, it will be filtered and won't be detected.

Lateral Suppression: it only works for unidirectional induction. When the lateral suppression function is used, it will filter the signal and won't detect.
