HLK-LD2410B FMCW 24G 24GHz Smart Human Presence Status Sensing Radar Heartbeat Sensitivity Mini Sensor Module High Detection

Product Information

Using waves to detect objects, mmWave sensors can accurately detect a person's breathing and movements. DEVICE_light_threshold' name : light threshold - type : horizontal-stack cards : - type : entity entity : 'sensor. This one can operate with just 5V power and can both be calibrated and monitored over BLE, although some folks have said the range and connectivity is a bit spotty. During testing, I experienced frequent disconnections and stability issues with the Bluetooth integration, as many others have also reported online.

Zone 2 starts where Zone 1 ends, so if Zone 2 is set to 300cm, it detects presence from 50 to 300cm measured from the sensor etc. With a detection range of up to 5 meters (16 feet) and an approximate angle of 60 degrees, it ensures comprehensive coverage. I didn’t do any additional configurations, but if you need to do this, then please, do not change the default password or the number of gates using the above software, as the Home Assistant Integration may stop working.Not sure about the use case for this one; it seems inferior to the LD2420 generally unless you wanted to use it with a 5V MCU like and Arduino.

This particular model is natively supported in ESPHome, you can go over all available options on this page. When connecting both, if it doesn't work, then try restarting the ld2410b, usually the logs are like "connected", some sec pass, "disconnected", if this happens and you have followed the first point then try restarting the ld2410b, if the connection is pending and you don't see the sensor in the app then try disconnecting the esp momentarily. The LD2410b version doesn't matter all that much but if you're on version 2 and find you have some problems you can try downgrading.DEVICE_still_target' name : still state_color : true - type : conditional conditions : - entity : 'switch. I can see that the Output Pin is getting high state as soon as I go into the sensor range, but HomeAssistant is getting the changed state after 2-4 seconds, sensor and Bluetooth dongle are 2m apart.

If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag.

That said I’ve a couple of 2410’s running as standalone BLE devices and they have been very stable, so its not a huge problem, but I would be good to have the choice of WiFi or BLE. I think this little guy can be a real game changer in the Home Automation world, but let me explain. Also is it possible to have a simpler version that tracks the presence of static and moving target ? 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 wrote it because the BLE protocol of the ld2410b is too chatty to reliably forward over a wifi network in urban areas due to interference. You can create three zones by specifying the distance in centimeters, indicating the maximum range the sensor should detect for each zone. Apart from that good job on that short moment when you saw the board in HA that should be a motivation.The radar target entity consolidates both states, requiring both to be clear for the overall presence to be considered clear, and vice versa. Its working principle is to use FMCW frequency-modulated continuous wave to detect human targets in the set space. This sensor is natively supported in Home Assistant and can be easily integrated with ESP32 and ESPHome. 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. With this sensor, I need a direct view of the BT proxy, otherwise it won’t work… Do you guys have the same problem?
