About this deal

After I’m ready with the wiring, I will plug the USB cable into a USB port on any working machine or I can use a power adapter. Oddly the built in bluetooth works fine across the room when connecting the phone app directly to the device but it’s absolutely rubbish when connecting bluetooth via HA.

I also included the provisioning package, which adds a text sensor that instantly shows you the MAC addresses of ld2410b devices as you power them on, to make it easier to find their addrs. I really wish LD2410 BLE integration works because adding LD2410B to HA is so simple with it but too bad it is buggy and unreliable.For example, you can turn on a specific light when occupancy is detected and turn it off when the area becomes unoccupied. To make your presence detection system functional, you need to wire the mmWave sensor to your device. With a detection range of up to 5 meters (16 feet) and an approximate angle of 60 degrees, it ensures comprehensive coverage.

The LD2410B module is a high-sensitivity human presence detector that uses Frequency-Modulated Continuous-Wave (FMCW) or somewhere you can see it as mmWave technology to detect humans.This product is mainly used in indoor scenes to sense whether there is a moving or micro-moving human body in the area, and output the detection results in real time. In this article, I am sharing a DIY guide for creating a simple presence sensor based on the HLK-LD2410 sensor and an ESP32 board, all coded through ESPHome and Home Assistant. If you plan to use the sensor in such an environment, take this into account and adjust accordingly. Once you restart again go to integrations page and then you will find your discovered ld2410 listed waiting to be Configured. As end result, I will have a new device inside Home Assistant with several entities/sensors and now I can start creating Home Assistant automations and scripts.

DEVICE_engineering_mode' state : 'on' card : type : vertical-stack cards : - type : horizontal-stack cards : - type : entity entity : 'sensor. Support GPIO and UART output , plug and play, and can be flexibly applied to different smart scenarios and terminal products. I will connect the Red USB wire which is the USB power wire to the VCC PIN on the LD2410B module and Black USB wire to the GND PIN on the module. Its working principle is to use FMCW frequency-modulated continuous wave, to detect human targets in the set space, combined with radar signal processing, accurate human body induction algorithm, to achieve high sensitive human presence status. Apart from that good job on that short moment when you saw the board in HA that should be a motivation.It’s my Smart Home Glossary that you can use as dictionary to find the meaning of the most common Smart Home words and abbreviations.
