      The human body micro-motion radar sensor module helps the hotel's intelligent transformation. With the advancement of technology, economic transformation and consumption upgrade, people's demand for tourism consumption is getting stronger and stronger. The hotel industry will usher in a new round of recovery from 2022. However, at present, various hotels have serious homogenization in the aspects of outer packaging, internal environment, and service links, and cannot attract customers with increasing personalized needs, especially those who have gradually become the main consumer groups after the 1990s.

      Human body micro-motion radar sensor module hotel intelligence

      The introduction of intelligence into the hotel industry has become a general trend. Innovative technologies in the hotel industry are constantly emerging, and how to use new technologies to promote the healthy development of the hotel industry has become a hot topic. In this context, the FR58L4 microwave radar sensor came into being.


      The FR58L4 human body micro-motion radar sensor module uses the Doppler principle. The microwave radar sensor transmits and receives high-frequency electromagnetic waves, uses the characteristics of microwaves to determine the movement of the covered object, and gives corresponding signals. The FR58L4 radar sensor is a modern product that combines the modern needs of smart homes and smart hotels.


      Basic functions, advantages and parameters of FR58L4 human body micro-motion radar

      basic function:

      1. Detection: Through the Doppler frequency shift effect, the relative velocity of the object can be detected, and whether the object is close or far away;

      2. Micro-motion detection: It can accurately detect the subtle movements of objects, such as people writing, typing on the keyboard, breathing, etc.

      3. Advantages: Small module size, long sensing distance, sensitive, wide angle, no dead angle, not affected by temperature, humidity, dust, strong anti-interference ability.

      Smart hotel applications, leading the modern experience, equipped with radar sensors, accurate sensing and signals, opening curtains, lights, TV, music and a series of linkage operations; when guests go out, they can set an alarm mode to monitor accidental intrusions to protect guests' privacy and property safety ; At night, guests can automatically turn on the bathroom lights to avoid the embarrassment of finding switches, allowing guests to feel the convenience and comfort brought by high-tech, greatly improving the experience of staying.


      No card to get electricity, save costs, seize the commanding heights of interests, when guests leave for a long time, when the human body micro-motion radar sensor module detects that there is no one in the room, it can automatically turn off air conditioners, TVs and other designated equipment to avoid wasting electricity and water resources. Digital and networking reduce energy consumption in hotel operations.


      So, how much can you save by using radar? Take the bathroom as an example:

      Assuming that the total power consumption of all electrical appliances in each bathroom is 300 watts, 60% of the guests do not have the habit of turning off the bathroom lights, exhaust fans and other equipment, the unused time of the guests is 10 hours/day, and the electricity price per kWh is 1 yuan, 200 The average occupancy rate of each guest room is 80%, and the power consumption expenditure = 200 rooms x 80% open rate x 1 yuan/degree x 0.3KW x 10 hours x 60% = 288 yuan/day. This product can automatically turn off the electrical appliances 5 minutes after the guest leaves the bathroom, which means that the bathroom can save the hotel: 365 days × 288 yuan / day = 105,120 yuan / year.


      In the hotel industry, technological progress is an important driving force for development. The development mission of the smart hotel is to continuously improve the customer's accommodation experience with smart product solutions. With the birth and commercialization of new low-power and small radar sensors, the application of radar technology in hotel intelligence will become an inevitable trend. "Cost saving + high-end technology + luxury experience" will be a wise choice for hotel management.


      The leader in products such as human body micro-motion radar sensors, plug in the wings of technology for your hotel!
