Sensitivity is manually adjustable with a potentiometer on the back of the device offering direct line of sight detection from roughly 8 to slightly over 30 ft 2 4 to 9 m.
Doppler x band radar detector sensor.
I brought similar dopplar radar from china.
It is mainly used in automatic door control safety guard system automatic video control system etc.
Weburban magnolia sensor board hooked up to a parallax x band sensor outputting audio feedback.
And the hb100 doppler radar modules are pretty cheap.
Hi i have recently purchased an x band sensor from a nearby store and i tried connecting it to arduino powering it up and using analod read to read the sensor value but the sensor shows constant value of 14 and there is very minute or no change when i try to move in front of it the sensor has also not got any pot for sensitivity adjustment.
This is the antenna oscillator as used in the x band motion detector made by parallax.
This module use 10 525 ghz band to detect moving.
The sensor is able to detect motion through walls and can be.
Most radar detectors are used so the driver can reduce the car s speed before being ticketed for speeding.
The x band motion detector s sensor is a common component in security systems and automatic door openers and can detect movements within a room yard or even on the other side of a wall.
This is a microwave moving object detector which is designed by doppler radar principle.
In general sense only emitting technologies like doppler radar or lidar can be detected.
This is a microwave moving object detector which is designed by doppler radar principle it is mainly used in automatic door control safety guard system automatic video control system etc.
It s a doppler radar sensor that operates in the x band frequency at 10 525 ghz and indicates movements with oscillations in its high low output.
This module use 10 525 ghz band to detect moving.
