ZRE-MSNCR HLK-LD1125H-24G Radar Sensor Body Sensor Module Motion Detection Sensor Microwave Human Detection Sensor Module for Smart Home

Features:
1.The product is compact and easy to carry
2.The module can penetrate non-metallic shells without the need for openings
3.It is used to determine the existence of the human body by detecting the accumulation of small amplitude movements such as human respiration
4.Compared to traditional mobile detection radar, it has higher accuracy and is less likely to miss alarms
5.The farthest sensing distance can reach 8 meters

Product Description
HLK-LD1125H-24G is a highly sensitive 24GHz millimeter wave human presence detection radar module. Unlike traditional radar, which detects large or small movements of the human body to determine the presence of the human body, the main feature of this module is to detect small movements such as accumulated human respiration to determine the presence of the human body. Therefore, compared to traditional motion detection radars, the accuracy of detecting human presence is higher. Not easily overlooked.

Frequency: 23.5G-24.5GHz
Modulation method: FMCW
Detection distance: 4m sit still, 8m exercise
Scope: Hanging height of 3m, coverage radius of static human body detection>2m
Power supply: 3.3-5V
Current: 80mA
Output serial port level: 3.3V
Detection cycle: adaptive
Antenna half power angle:+/-22 * (horizontal/vertical)
Data format: serial port ASCII output

Take care
1. When the radar is working, there should be no metal or other obstructing electromagnetic wave transmission media blocking the antenna in front; •
2. Different shell materials and the distance between the module and the inner surface of the shell may result in different returned spectral energy and parameter settings, which need to be fine-tuned according to actual conditions. It is generally recommended that the module be 5-6mm away from the casing, which can be adjusted based on actual measurement. •
3. We recommend that users first test according to the default settings of the module. If the effect is not as expected, the shell structural components can be sent to the original factory, which will conduct testing and adjust a reference setting. •
4. The module is used for detecting human movement and presence, so the distance value provided is not an accurate distance measurement, only indicating the approximate distance of the target. •
5. If the tested person is sitting with their back to the radar, the sensing effect will decrease. Because when facing the radar with the back, the fluctuations in the chest or abdomen caused by breathing cannot be detected. •
6. It is recommended to use plastic or other materials as the outer shell, as radar is a very sensitive module in the human body. If a large attenuation material is used as the outer shell, it may affect the detection. •
5. Avoid air conditioning vents, fans, and other objects during installation. •
