The TC-CK1-SBE INTERSECTOR™ is a microwave-based motion and presence sensor used for intersection control. The unit interfaces with a traffic-control cabinet, and outputs signals when vehicles are present in a user-defined zones. Zones are created using an X-Y coordinate system, and operation is verified and optimized using a laptop with a web browser as part of the installation process.
· The living body presence detection solution is based on the microwave respiration detection technology, using a patented low-impedance antenna and an exclusive presence sensing algorithm to detect the presence of the human body by detecting the expansion of the chest and abdomen when the body is breathing. At the same time, algorithms and microwave detection …
· Contactless detection of human beings via extracting vital sign features (VSF) is a perfect technology by employing an ultra-wideband radar. Only using Fourier transform, it is a challenging task to extract VSF in a complex environment, which can cause a lower signal to noise ratio (SNR) and significant errors due to the harmonics. This paper proposes an improved signal processing algorithm ...
· Single sensor detector algorithms do detect congestion fairly consistently, but do not readily detect incidents. Our work builds upon the single sensor detector and only elevates the system cost to a multiple sensor solution for confirmation of an incident. This allays the continuous cost of the communication between multiple sensor system, and simultaneously reduces the false alarms ...
· In these pages, we propose a project for a microwave detector based on a dedicated module, in breakout board format. Circuit diagram. Our sensor is basically a radar based on the Doppler effect, composed of an electronic section described by the circuit diagram, in which we’re going to insert the sensor’s breakout board. The latter is based on the RCWL9196 integrated that interfaces with a …
· Presence detector with microwave. By Boris Landoni on April 23, 2019 Tweet; Pin It; Tweet . Pin It . It detects stationary and moving people just like a PIR, but it can do that also behind doors and thin walls, by taking advantage of the Doppler effect. The detection of people, animals and hot bodies in general has been done for years using passive infrared radars, also known as PIR, which ...
A presence detector monitors the detection zone for occupancy; if a person is sensed then the detector will automatically turn the lighting on. When the area is vacated, the lighting will turn off after a preset time delay. Most of our PIR sensors and microwave sensors have a built in light level (lux) sensor which will keep the lighting off if there is enough natural light available.
· Generally, the algorithms developed for the three spectrums using either spectral, spatial or temporal information. One exception in microwave sensors is that polarization information is also used. The most significant drawback of dust storm detection using ultraviolet and microwave sensors is the coarse spatial resolution. Thus, in this paper, we will focus on reviewing the algorithms in the …

detection Doppler sensor systems. The cumbersome microwave radar sensor of the past has been replaced by smaller, smarter, and higher sensitivity systems. An early respiratory monitoring system [4] was attached to an X-ray and triggered this machine automatically by instance of respiration. This system is quite simple. It consists of an ...
IP67 rated Microwave Presence Detection Switches. Ideal for outdoor or indoor use the microwave presence detectors can be wall or ceiling mounted and are designed for the automatic switching of lighting, heating and air conditioning loads. The sensor detects movement, within its range of detection, by emitting low power microwave signals and ...
· In my previous article, I introduced the use of TI’s 77-GHz millimeter wave (mmWave) sensors for interior sensing applications like child presence detection, passenger detection and intruder detection.. The need for child presence detection has found its place on the EURO NCAP roadmap, driving car manufacturers to offer this feature. . Adding child presence detection …
We present two oscillation control algorithms for resonant sensors such as vibratory gyroscopes. One control algorithm tracks the resonant frequency of the resonator and the other algorithm tunes it to the specified resonant frequency by altering the resonator dynamics. Both algorithms maintain the specified amplitude of oscillations. The stability of each of the control systems is analyzed ...
· Microwave sensors also known as Radar, RF or doppler sensors are electronic devices capable of detecting motion from walking, running to crawling in an outdoor environment by using electro-magnetic radiation. It is able to detect motion by applying the Doppler effect and project microwaves which will bounce off surfaces and return to the sensor.
· Let's look at a Chinese Microwave Motion (Occupancy) Detector purchased off EBAY for around five dollars. Takes a DC supply of 12 to 24 Volts and has a stat...

· Microwave Sensor advantages. Microwaves are the electro-magnetic radiations whose frequency ranges from GHz to 300 GHz , These waves are mostly used for the non-broadcasting issues , Microwave motion detectors emit microwaves into the specific region and they detect any intrusion by analyzing the received microwaves frequency after the reflection from the intruder .
· We present an algorithm for hemispheric scale detection of autumn soil freezing. ... Compared to data products based on microwave sensors operating at higher frequencies ( Kim et al., 2011), L-band observations exhibit deeper soil penetration depths, reduced influence from overlying vegetation, and hence increased sensitivity to the freezing process (Rautiainen et al., 2014). …
The imaging algorithm is based off a previously proposed microwave imaging in space-time algorithm (MIST) that was implemented for breast cancer detection. Simulated data was obtained from a wearable antenna array system and processed in the modified MIST algorithm. In addition, experiments were also carried out to test the imaging algorithm on data obtained from the fabricated sensors on ...
