Hi-Link HLK-LD2410B, 24GHz Human Presence Radar Sensor

$40.5 $61.16
LD2410B is a high­ly sen­si­tive 24 GHz human pres­ence sens­ing mod­ule. The work­ing prin­ci­ple is to use FMCW (Fre­quen­cy Mod­u­lat­ed Con­tin­u­ous Wave) to detect human tar­gets in the set space, com­bined with radar sig­nal pro­cess­ing and pre­cise human body sens­ing algo­rithms, to achieve high-sen­si­tiv­i­ty human pres­ence state sens­ing. It can rec­og­nize human bod­ies in both mov­ing and sta­tion­ary states and cal­cu­late aux­il­iary infor­ma­tion such as the dis­tance of the tar­get.The prod­uct is main­ly used in indoor scenes, per­ceiv­ing whether there is move­ment or micro-move­ment of the human body in the area and out­putting results in real time. The far­thest sens­ing dis­tance can reach 6 meters, with a res­o­lu­tion of 0.75 m. It pro­vides con­fig­u­ra­tion tools that can con­fig­ure sens­ing dis­tance range, sens­ing sen­si­tiv­i­ty in dif­fer­ent inter­vals, and unmanned delay time. It sup­ports GPIO and UART out­puts, fea­tures plug-and-play oper­a­tion, and can be flex­i­bly applied to dif­fer­ent intel­li­gent sce­nar­ios and ter­mi­nal prod­ucts.PRODUCT FEATURESFre­quen­cy: 24G–24.25 GHzMod­u­la­tion method: FMCWDetec­tion dis­tance: 0.75–6 m adjustableDetec­tion angle: ±60°Pow­er sup­ply: 5 VCur­rent: ~79 mAOut­put ser­i­al port lev­el: 3.3 VSweep band­width: 250 MHz (in com­pli­ance with CE/FCC cer­ti­fi­ca­tion stan­dards)Envi­ron­men­tal tem­per­a­ture: ‑40 ℃ ~ 85 ℃Data for­mat: ser­i­al port ASCII out­put / high and low lev­el 3.3 V & 0 VPack­ag­ing form: default with pin, cus­tomiz­able seat or with­out pinCONFIGURATION DEBUGGINGInter­face type: 1.27 mm × 5‑PIN pin arrange­mentOUT — induc­tive out­put high lev­elTX — ser­i­al trans­mis­sionRX — ser­i­al port recep­tionGND — pow­er groundVCC — pow­er input (5 V volt­age)The mod­ule IO lev­el is 3.3 V.The default baud rate for the ser­i­al port is 256000, with 1 stop bit and no par­i­ty bit.
