HB100 Microwave Radar To Arduino


Doppler shift output from IF terminal when movement is detected. The magnitude of the Doppler Shift is proportional to reflection of transmitted energy and is in the range of microvolts (μV). A high gain low frequency amplifier is usually connected to the IF terminal in order to amplify the Doppler shift to a processable level. Frequency of Doppler shift is proportional to velocity of motion. Typical human walking generates Doppler shift below 100 Hz. (hb100_microwave_sensor_datasheet)




HB100 microwave radar to Arduino



The purpose of radar is to provide some form of warning, whether as part of a military surveillance system, a weather-tracking system, or our efforts to better know the universe. Short for radio detection and ranging, radar was initially developed for military use (to detect ships and aircraft during World War II), but now has many applications. Radar systems have matured with the development of different technologies, such as RF/microwave amplification and digital signal processing (DSP). They are now used on earth, at sea, on the road, and even in outer space.


The HB100 sensor is a microwave moving object detector designed using Doppler radar principle. Unlike ordinary infrared detectors, microwave sensors detect the motion of an object by detecting microwaves reflected from the object.


Doppler radar uses the same principles discovered by Christian Doppler when observing sound and applies them to electromagnetic waves. Using the Doppler Effect is a great way to measure relative speed. In practice, the Doppler Effect is a shift in frequency perceived by a receiver from a signal source due to relative movement of the sender and/or receiver. In a Doppler radar system, a known frequency signal is transmitted from an antenna which is pointed at a reference object. A separate antenna is used to receive the signal that is reflected back from the reference to measure the Doppler shift of the signal. A simple Doppler module, also called as the microwave motion sensor, can be easily integrated into multiple types of systems for various purposes. Doppler modules have an internal oscillator used to produce the signal frequency transmitted as the source. The received signal is then mixed with this set signal, which produces an output that is a sinusoid containing the frequency difference between the sender and receiver signals. Usually, these values need to be processed in a tangible way and is usually done with the help of a microcontroller.

The microwave motion sensor is a microwave moving object detector designed using the principle of Doppler radar. Unlike ordinary infrared detectors, microwave sensors detect the movement of objects by detecting microwaves reflected by the objects. The detection objects will not be limited to the human body, and there are many other things. The microwave sensor is not affected by the ambient temperature, has a long detection distance, and has high sensitivity. It is widely used in industrial, transportation, and civil devices, such as vehicle speed measurement, automatic doors, sensor lights, and reversing radar. Due to the universality of microwave sensor detection objects, in actual life applications, another sensor will be used for targeted detection. For example, the microwave sensor + infrared pyroelectric sensor can effectively judge whether someone passes by, will not be interfered by sunlight, clothing color, and will not react to other objects.
