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. This will be returned to desertcart

## Features

- 【24GHz High Precision Stillness and Motion Detection】: With the Doppler radar technology and 24GHz working frequency, combined with FMCW and CW multi-mode modulation, this mmWave Radar sensor can accurately detect all movements, micro-movements, and extremely weak movements within a 9-meter range. Whether it's subtle human movements or stillness and sleep states, this sensor can accurately perceive them.
- 【Compact Size, Easy to Integrate】: The mmwave sensor's size is only 24*28mm, and it uses a 1Tx1Rx antenna structure, which is very suitable for integration into various systems or mobile devices, providing great convenience for various projects.
- 【Strong Anti-interference Ability (From -40 to 85℃)】: This mmwave presence sensor has outstanding anti-interference ability and can work stably in an environment of -40~85℃. Whether it's snow, fog, haze, temperature, humidity, dust, light, or noise, none of these can affect its working efficiency, ensuring stable performance in any environment.
- 【Wide Range of Application Scenarios】: Due to its high precision and strong anti-interference ability, this presence sensor is widely used in collision warning for autonomous driving cars, human activity monitoring in smart homes, precise control in industrial automation, non-contact monitoring in healthcare, inventory management in retail and logistics, obstacle avoidance and positioning in drones.
- 【High Flexibility with Various Output Options】: This human presence sensor provides two types of sensing result output methods. You can choose to output through the serial port or through the I/O port, which is very flexible and easy to expand. At the same time, it provides various available example codes that can meet the needs of makers in different projects.
