Radar human body microwave sensor 5.8GFMCW radar sensing scheme

Radar human body microwave sensor 5.8GFMCW radar sensing solution, smart home is people-oriented, and human body sensors play an indispensable role in it.

Radar human body microwave sensor intelligent lighting human body induction control can accurately control the sensing range, and is not affected by external factors such as temperature, strong light, and wind. Generally speaking, it can meet the high requirements for human sensors: high precision, low power consumption, anti-interference, and beautiful appearance.

5.8G presence sensing solution for radar human body microwave sensor FMCW ranging! The microwave radar has high upgrade accuracy, low power consumption and strong anti-interference ability.

Detect static personnel; accurately define the detection range, greatly reduce false alarms; reduce volume and power consumption, enrich application scenarios; anti-interference; products are more beautiful and generous.

Back to our customer's usage scenario, as long as someone is in the toilet and office, the radar body microwave sensor can be used to detect the presence of the human body, whether it is stationary or moving, without worrying about environmental interference.

Compared with distance test, multi-target test and angle test, FMCW and FSK have great advantages. Because it has great advantages. Compared with CW technology, FMCW adds multi-dimensional information such as distance and angle, so the accuracy and sensitivity of FMCW micro-motion and presence detection are higher.

When we design smart home products, we can match different human sensing technologies to meet our scenarios, after all, there are no better products, only better solutions. In high-end residences and hotels, detecting whether someone is controlling the indoor air conditioner and fresh air system through sensors is an important function of smart homes and smart hotels.

Radar human body microwave sensor 5.8GFMCW solution SOC radar chip development, integrated digital phase-locked loop, support FMCW ranging, delineation of sensing area, shielding interference outside the area, low power consumption, low cost, typical value less than 0.08W, single-chip integration High-performance 32-bit MCU, part of the host computer system of this MCU can be replaced in addition to processing the internal signals of the radar.

Radar human body microwave sensor This solution has excellent microwave characteristics and strong sensitivity, and can detect weak breathing and even heartbeat signals when the human body is not moving. At the same time, FFT and algorithm support are used in hardware to extract and confirm effective breathing characteristic information. The smart toilet detects whether it is occupied by the presence of the human body; the smart kitchen and bathroom, smart light control, and smart robot detect whether it is turned on by the presence of the human body.

The radar human body microwave sensor can be used in parking lot automatic lighting systems, street lighting automatic lighting systems, corridor automatic lighting systems, and can meet the ultra-low power consumption requirements of battery-powered application scenarios.
