Top 10 Reasons to Choose Smart Presence Sensor Micro Motion Switch Finished Products

Ten reasons to choose the finished product of the smart presence sensor micro-motion sensor switch Inductive switches are widely praised and expected. At the same time, due to the advantages of intelligent detection such as the details of the finished product of the smart presence sensor micro-motion sensor switch and years of experience in smart products, our company has long applied the sensor switch technology to smart life.

Especially since this year, the radar sensor switch has gradually opened up in the new era, but in order to integrate the new normal sales market, it is the key. the most important is. As a technical intelligent radar sensor switch manufacturer, according to the long-term development trend, we will vigorously strengthen independent innovation, seek diversification in all aspects of technological upgrading, and promote the development of commercialization trends.

Therefore, from the perspective of radar sensor switch products, through the integration of high technology, new materials and new functions, a breakthrough in the finished product of intelligent presence sensor micro-motion sensor switch is achieved, the construction of intelligent application market channels is strengthened, and the original lighting requirements are returned. , get rid of the disorderly advantage of price competition.

After years of research, radar sensor switches are not as simple as they seem, but as a standard smart presence sensor micro-motion sensor switch finished product manufacturer, we have to invest a lot of time and effort, building a well-known brand is not a day, only good Products can better serve the public.

However, judging from the current situation, new manufacturers do not seem to be aware of this layer, with net expansion, light upgrades, and a general lack of innovative spirit, and they have not followed the over-expansion blindly from their own perspective.

Over the years, our company has specialized in the finished products of smart presence sensor micro-motion sensor switches. The research and development of products in the smart home industry, its patented product solves the problem of the application environment of sensor products, and is a real smart radar sensing product that can be used in various major places.

For sensing technology, we probably know the most about radar sensing and human infrared sensing. These two sensing technologies are often used in automatic control occasions such as automatic doors and sensing lights, but in fact, the working principles of these two sensing control technologies are different, and there are also some differences in use. Next, let's take a look at the differences between them.

Radar sensing technology: Like the microwave sensor, it adopts the Doppler radar sensing principle and emits 5.8ghz radar signals. Once a moving object enters the sensing range, the radar signal waveform changes, which triggers the movement of the radar sensor. It is the most user-friendly sensing technology and is not affected by ambient temperature and loudness. It is an ideal smart presence sensor micro-motion sensor switch finished product for indoor and outdoor!

Human body infrared sensing technology: Using the principle of pyroelectric infrared sensing, the sensor action is triggered by collecting infrared energy changes. Affected by the ambient temperature, when the ambient temperature in summer is close to the human body temperature, there is no change in infrared energy when people enter the sensing range, so the sensing performance of the human body is very sensitive in summer. Due to temperature, errors are also easily reported, so this sensing technique is rarely used.

1. The working principle of radar sensing

The radar sensor consists of oscillator, amplifier and detection circuit. During operation, the oscillator emits ultra-high frequency electromagnetic waves through an antenna printed on the printed circuit board. If there is an object moving within the sensing range of the radar sensor switch, the antenna will receive the electromagnetic wave reflected by the moving object, the reflected electromagnetic wave frequency and the electromagnetic wave frequency, and there will be a certain frequency difference, which is amplified by the receiving circuit. After shaping, a control signal can be output to control the work.

2. The working principle of human infrared sensor

Human infrared sensor is composed of Fresnel lens, pyroelectric sensor and sensing signal processing circuit. Since the pyroelectric sensor used has an infrared filter in front of it, it can only detect infrared signals with a wavelength of more than 10 μm from the human body. This is equipped with a Fresnel lens for increased sensitivity. When working, as long as someone walks in the monitoring area of the pyroelectric sensor, the sensor will output a corresponding electrical signal, and output a control signal after the induction signal processing circuit to control the load.

The disadvantage of human body infrared sensing is that the use of directionality can only be controlled when someone moves in front of the sensor, which is prone to false alarms.

Generally speaking, in terms of performance, the finished product of the smart presence sensor micro-motion sensor switch is completely superior to the human body infrared sensor. It has a greater range, lower power consumption, and a smarter sensor that works well in any scenario.
