Reliable presence detection

We deployed these in several conference rooms to manage HVAC systems. Unlike PIR sensors, this one knows people are still in the room even if they are sitting still at their desks.

Great value but needs calibration

The hardware quality is excellent for the price. However, you need to spend some time tuning the sensitivity parameters via UART to get the exact detection zone you want. Once configured, it is very reliable.

Low power consumption as advertised

I am using this in a battery-powered project, and the sleep current is genuinely low. It has extended my device's battery life significantly compared to passive infrared sensors.

Best 24G sensor in this price range

I have tested multiple brands, and the Hi-Link LD2410S offers the best balance of performance and cost. The ability to filter out static objects while detecting humans is impressive.

Perfect for smart home automation

This sensor is incredibly sensitive and detects even subtle breathing movements. I integrated it into my bedroom lighting system, and it works flawlessly without false triggers from outside the room.

Compact and easy to solder

The module is very small, which is great for tight enclosures. The pinout is standard, making it easy to interface with ESP32 or Arduino boards. Documentation could be slightly more detailed.

5 FAQ

Q: Can the detection distance be limited to avoid triggering from the hallway?

A: Absolutely. You can configure the maximum detection distance and gating zones via serial commands to restrict the sensing area to specific ranges.

Q: Is there a library available for ESPHome integration?

A: Yes, this sensor is natively supported in ESPHome. You can find the component documentation under the 'ld2410' section in the official ESPHome guides.

Q: What voltage level does the UART interface use?

A: The UART interface operates at 3.3V TTL logic levels. Please ensure your microcontroller is 3.3V compatible or use a level shifter if connecting to a 5V system.

Q: Does this module come with an antenna?

A: Yes, the module includes a built-in PCB antenna. No external antenna connection is required or available for this specific model.

Q: Can this sensor detect a person sitting completely still?

A: Yes, the LD2410S uses mmWave radar technology capable of detecting micro-movements such as chest expansion from breathing, allowing it to identify stationary human presence.
