Product description
These mmWave Human Presence sensors are a great addition to your smart home network. Compared to its little sibling the LD2410B these modules feature a greatly improved antenna design to provide for superior sensitivity and range. They are however lacking Bluetooth so need to be used in conjunction with a USB to UART adapter or a microcontroller such as ESP32. You can pair this with ESPHome for use with Home Assistant. These fill the gap left over by traditional PIR motion detectors, that will forget you are in the room if you are not moving. 

Hailingco Electronics has developed a highly sensitive human presence sensing module called the LD1125H. This module uses FMCW FM continuous wave technology to detect human targets in a space, combined with radar signal processing and accurate human sensing algorithms to achieve high precision. 

The LD1125H is mainly designed for indoor use, capable of detecting moving or slightly moving human bodies in the area and outputting real-time detection results. It can accurately identify human bodies in motion or at rest and calculate the distance of the target and other auxiliary information. With a sensing distance of up to 4 meters for breathing and 8 meters for movement, this module provides visual configuration tools to easily customise the sensing distance range and sensing sensitivity in different zones to suit specific application requirements. Whether it be for home automation or security applications, the LD1125 with ESPHome and Home Assistant support is a versatile solution for human presence detection.

Features

  • Plug and Play Sensor Module: This module offers easy assembly and requires minimal setup time.

  • Long-range Sensing: This device provides the longest sensing distance of up to 8 meters, making it suitable for various indoor sensing applications.
  • Wide Detection Angle: With a large detection angle of up to ±22 degrees, this device can cover a broad area and detect movement from different angles.
  • Accurate Identification: The module offers accurate identification within the sensing interval and supports the division of the sensing range. It also shields the interference outside the sensing interval.
  • Multi-level Intelligent Parameter Adjustment: This device offers multi-level intelligent parameter adjustment, allowing it to adapt to various changing scenarios.
  • Visual Debugging and Configuration Tools: This device provides visual debugging and configuration tools that make it easy to configure and debug the module.
  • Compact and Simplified Design: The module has a small and simplified design, with the minimum size being only 31mmx16mm.
  • Various Installation Methods: The device supports various installation methods such as ceiling hanging and wall hanging.
  • 24GHz ISM Band Compliance: The device operates on the 24GHz ISM band, compliant with FCC and CE spectrum regulations.
  • Power Supply: This module supports a wide voltage power supply range of 3.3-5V.
  • Ultimate Cost-Effective Choice: Overall, this device offers the ultimate cost-effective choice for users looking for a high-performance sensing module.
