FMCW – MoWa inside

AFMCW (Frequency-Modulated Continuous Wave) technology operates by continuously emitting a frequency-modulated signal. The sensor sends out a wave that gradually changes in frequency over time. When this wave reflects off an object and returns to the sensor, its frequency is compared to the emitted wave. The difference between these frequencies, known as the beat frequency, is directly proportional to the distance between the sensor and the object.

FMCW technology provides highly precise distance measurements with continuous data updates, which enables the sensor to detect instantaneously both stationary and moving objects.

By continuously analysing changes in frequency over time, FMCW technology can also determine an object’s velocity and direction, making it highly effective in applications requiring real-time tracking and precise positioning.

MoWa inside, which is based on FMCW technology, measures the distance and speed of objects in the detection field. By transmitting a modulated wave and measuring the frequency shift of the reflected signal, it can detect and classify people and all types of vehicles, whether moving or standing still.

Radar & Active Infrared Sensor

An infrared (IR) sensor is an electronic device that measures and detects infrared radiation in its surrounding environment. Having a light emitting diode (LED) and a receiver, an IR sensor emits and detects infrared radiation simultaneously. When an object comes close to the sensor, the infrared light from the LED reflects off of the object and is detected by the receiver.

Active IR sensors act as proximity sensors, and they are commonly used in obstacle detection systems (such as in robots).
