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

Product Information

Their capability in terms of radar detection is identical, whichever you choose it will perform the same. Let’s see what else is needed for our DIY Human Presence Detection along with the LD2410B or C module. In addition to being sensitive to the moving human body, it can also sensitively sense the static, fretting, and sitting and lying movements of the human body that cannot be recognized by traditional solutions. Its working principle is to use FMCW frequency-modulated continuous waves to detect human targets in the set space. Also I have about 99% uptime with the sensors, if they get disconnected is for 5 secs tops and once a day tops.

New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging . It utilizes FMCW frequency-modulated continuous wave technology to detect human targets within a defined space.During testing, I experienced frequent disconnections and stability issues with the Bluetooth integration, as many others have also reported online. If you receive a product damaged during shipment, please notify us within the 3 days of you receive the product, supported by the proper pictures and description.

As I understand it, if I want to use this with ESPHome the connections to be made are UART and 5V power only, leaving the "OUT" pin unconnected. type : vertical-stack title : 'DEVICE' cards : - type : horizontal-stack cards : - type : entities entities : - entity : 'switch. 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. To create your own presence sensor based on the Hi-Link LD2410, you are going to need a couple of things. DEVICE_engineering_mode' state : 'on' card : type : vertical-stack cards : - type : horizontal-stack cards : - type : entity entity : 'sensor.I connected the board with an USB cable to my PC and used the ESPHome Web Flasher to initialize the device. Make sure to grab the LD2410B or LD2410C versions, because these boards come equipped with Bluetooth and have been confirmed working with Home Assistant. Very important, when doing the build files, or however you flash the esp, you MUST clean the build files every single time before doing another sensor, otherwise it won't work.

The reason to use Bluetooth is so that you can have multiple ld2410b sensors and relocate them around their esp32 hub. I have noticed that entities like XXXDistance, XXXEnergy are very chatty and have a lot of data in the HA, which means they constantly push small amount of data, great ability for advanced projects and debug scenarios, but may be a little overkill for the basic needs. With support for GPIO and UART output, it offers plug-and-play functionality, making it adaptable for different smart scenarios and terminal products. 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. I noticed that with the latest esphome 7 I can't get more than one sensor to work with the same code.ld2410 : id : my_ld2410 api : services : - service : set_ld2410_bluetooth_password variables : password : string then : - bluetooth_password. 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. A. My bluetooth proxy can only have 3 active connections which it already has and the LD2410B is being dropped in favour for the other devices.

This module gives real-time detection results and it is perfect for indoor use, but it is also rated that can work from -40 to +85 degrees Celsius, so I guess if you waterproof it somehow it can be used outside as well. A standard procedure is this: clean build, connect first sensor, second clean build, connect second sensor, clean build files, connect both. No longer need to assemble boards yourself, JLCPCB helps you assemble the part HLK-LD2410B-P for free.DEVICE_still_distance' name : still - type : horizontal-stack cards : - type : entity entity : 'sensor. I have the LD2410C and it immediately shows up in the app and appears to work fine, but multiple nearby bluetooth proxies (which otherwise work fine) are not detecting this device at all. For example, you can turn on a specific light when occupancy is detected and turn it off when the area becomes unoccupied. out_pin_presence_status ( Optional): When in engineering mode, indicates whether the OUT pin indicates presence or not, otherwise false.
