The most crucial aspect of millimeter-wave radar is its algorithm. The algorithm is very complex, and it is not something that the general public can develop. Typically, only doctoral researchers from military research institutions and similar experts can work on it. Therefore, our millimeter-wave radar module does not support direct secondary development on the module chip for customers. In most cases, it requires an additional MCU (Microcontroller Unit) to communicate with the millimeter-wave radar module via UART (Universal Asynchronous Receiver-Transmitter) serial communication. If there are customized requirements, customers can approach the original manufacturer for customized development.

We only provide people counting and tracking functionality. We do not include any safety-related features such as breath detection, fall detection, or sleep monitoring. Implementing such safety-critical functions could lead to severe consequences if accidents occur. It is important to emphasize that the limitation on precision is not specific to our company alone; in fact, no millimeter wave radar can achieve absolute accuracy. Some other manufacturers may have attempted to include such features, but they too cannot guarantee 100% accuracy, and the risks involved are substantial. Safety-critical applications require meticulous testing, certification, and redundancy to minimize the potential for accidents. As a result, our product focuses solely on reliable people counting and tracking functionalities.

 Automotive autonomous driving radar measures the relative motion of objects while in motion, and its product design can be likened to a telescope. Home radar, on the other hand, is installed in a fixed position and measures subtle movements, akin to a microscope. The algorithm architectures for these two types of radars exhibit significant differences."

Currently, there are three installation methods for radar detection: top-mount, slant-side mount, and side-mount.

Top-mount: Used in places like bedrooms, bathrooms, etc.

Side-mount: Used in locations such as conference rooms, large classrooms, etc.

Slant-side mount: An installation method that falls between top-mount and side-mount.

Phenomenon 1: The radar scans a large area, and movement next to the entrance or behind a wooden wall is detected. Adjustment method: Reduce radar sensitivity and use scene setting provided by the radar.

Phenomenon 2: The radar is directly facing an operating air conditioner or fan below. Adjustment method: Adjust the radar position to avoid facing the air conditioner or fan directly.

Phenomenon 3: Objects shaking due to air conditioning airflow. Adjustment method: Non-metallic objects, such as cotton items, will not cause false alarms. Metallic objects need to be fixed.

Phenomenon 4: The radar is not properly fixed, leading to false alarms due to vibrations. Avoid mounting instability and vibrations.

Phenomenon 5: Occasional movement by pets, birds, or other small objects. Due to the radar's high sensitivity and ability to detect minor movements, it is challenging to eliminate this interference.

Phenomenon 6: Occasional misjudgment caused by power interference.

Phenomenon 1: The human body is outside the radar range.

Please refer to the radar scanning range and adjust the installation angle accordingly. The radar measurement range varies slightly in different environments due to differences in electromagnetic wave reflection areas.

Phenomenon 2: False outputs caused by metal obstruction.

Thick office desks, metal chairs, or other metallic objects can obstruct electromagnetic waves and result in misjudgments.

Phenomenon 3: Differences in scanning angles.

If the radar fails to scan the torso area, it may lead to misjudgments.

Phenomenon 4: Radar sensitivity is too low.

Please adjust the radar settings to increase sensitivity for improvement.

The radar itself does not have communication functionality. It provides standard serial port output, and users can develop relevant upper computer IoT applications based on their desired communication protocols.

In general, the maximum installation height of MS72SF1 is less than 3 meters for both top-mount and slant-side mount configurations.
