Its compact 24x28mm form factor and dual output modes (serial and I/O port) make it highly adaptable for integration into smart home, automotive, healthcare, and industrial applications. Built to withstand extreme temperatures (-40 to 85°C) and environmental interference, it ensures reliable performance in diverse conditions. ## Description Introduction This 24GHz millimeter-wave radar sensor employs FMCW, CW multi-mode modulation and separate transmitter and receiver antenna structure. In working, the sensor first emits FMCW and CW radio waves to the sensing area. Next, the radio waves, reflected by all targets which are in moving, micro-moving, or extremely weak moving state in the area, are converted into electrical signals by the millimeter-wave MMIC circuit in the sensor system. After that, these signals will be sent to the processor and processed through the related signal and data algorithms. Then, the target information can be solved out. The millimeter-wave radar can sense the human presence, stationary and moving people within the detection area. Moreover, it can even detect static or stationary human presence such as a sleeping person. There are two ways provided to output detection result: serial port and I/O port switch quantity. Besides that, the sensor module features strong sensing reliability, high sensitivity, small size, easy to be used or embedded in applications. Specification Power Supply: 3.6~5V Operating Current: 90mA Detection Distance: 9m Equivalent Transmit Power: 9-12dBM Beam Angle: 100*40° Modulation Mode: FMCW, CW Operating Frequency: 24GHz Operating Temperature Range: -40~85℃ Baud Rate: 115200 Dimension: 24*28mm/0.94*1.10" Shipping List mmWave - Human Presence Detection Sensor (9 Meters) ×1 Review: Mixed Experience with DFROBOT and HLK-LD2410C for mmWave Radar Integration - I recently purchased both the DFROBOT and HLK-LD2410C mmWave Radar modules for a project involving home automation and detection applications. After thorough testing and evaluation, here's my feedback: DFROBOT: Detection Range: The DFROBOT boasts a longer detection range, which initially intrigued me. However, in practice, I found the reliability to be a major concern. The longer range is compromised by frequent inconsistencies in detection. Configuration: Configuring the DFROBOT with ESP32 and ESP8266 on ESPHOME proved to be less straightforward than expected. The setup process was not as user-friendly as I had hoped, leading to frustration and time-consuming troubleshooting. HLK-LD2410C: Detection Range: While the HLK-LD2410C has a shorter detection range compared to DFROBOT, I found it to be much more reliable in real-world scenarios. The consistency in detection made up for the reduced range in my specific use case. Configuration: Setting up the HLK-LD2410C with ESP-01 and integrating it with ESPHOME was a smoother process. The straightforward configuration made it a more attractive option, especially for those looking for a hassle-free setup. Price: One of the standout features of the HLK-LD2410C is its affordability. Despite the shorter detection range, the cost-effectiveness of this module adds significant value, especially for budget-conscious projects. Bluetooth Feature: The inclusion of Bluetooth in the HLK-LD2410C is a notable advantage. However, I experienced challenges in getting it to work seamlessly with Home Assistant. For now, I have opted to use an ESP-01 wired to the HLK running ESPHOME, with WiFi connectivity to Home Assistant. In conclusion, both the DFROBOT and HLK-LD2410C have their strengths and weaknesses. If an extended detection range is crucial, the DFROBOT may still be worth considering, but be prepared for potential reliability issues. On the other hand, the HLK-LD2410C offers a reliable and cost-effective alternative with a more straightforward setup, making it a preferable choice for certain applications. Consider your project requirements carefully before making a purchase decision.
