Product Description: YJJ LD2410C 24G Features Intelligent Sensor With Inductive Radar Module Bluetooth Functionality
Features: I. Core Parameters Radio Frequency Parameters Operating Frequency: 24 - 24.25 GHz, FMCW Frequency Modulated Continuous Wave, Bandwidth 250 MHz (CE/FCC Certified) Antenna Architecture: 1 Transmit 1 Receive (1T1R) Detection Performance Static Human (Sitting / Sleeping, Minimal Breathing Movement): 0.75 - 6m Human Movement: Maximum Distance 8m Detection Angle: Horizontal ±60° (120° Wide Angle), Measuring Distance Step 0.75m Adjustable Electrical Specifications Power Supply: DC 5V, Operating Current ≈ 79mA, Power Supply Recommendation ≥ 200mA Pins (5-pin 2.54mm standard pin header: VCC/GND/OUT/RX/TX) OUT: 3.3V Level Output, Presence = High, Absence = Low (Switching Quantity) TX/RX: 3.3V TTL Serial Port, Default Baud Rate 256000, ASCII Protocol, Can Output Distance / Presence Status Operating Temperature Range: -40°C - +85°C, Resistant to High and Low Temperatures Size: 16 × 22mm (Compact Surface Mount Type, Superior to LD2410B Slim Model) Additional functions Built-in light sensor detection + Bluetooth debugging, mobile app "HLKRadarTools" for wireless sensitivity adjustment, delay setting, detection range, and OTA firmware upgrade II. Product Features (Compared with Infrared PIR) Capable of detecting stationary human: Even if a person is sitting still or sleeping with slight chest breathing, it can be recognized. PIR only detects movement and may mistakenly turn off the light. Penetrability: Can penetrate plastics, acrylics, and thin wooden boards, unaffected by darkness, smoke, temperature, or curtains. Protection against false triggering by small animals: Can be software-protected against interference from small-sized animals like cats and dogs. Dual output: OUT switch quantity (simple drive for relays) + UART serial port (for MCU/PLC to collect data) III. Application Uses 1. Smart Home (Main Product) Human-sensing lights, magnetic track lights, entrance / bathroom lights turn on when people come and turn off after they leave with delay. Air conditioners, fresh air units, bathroom heaters: Power on when someone is present, power off in standby mode for energy saving when no one is present. Smart toilets, bathroom mirror lights: Start and stop based on human presence 2. Office / Commercial Office, meeting rooms: Intelligent lighting, energy-saving for when the room is empty Corridors, elevator carriages have detection, escalators with human presence start and stop 3. Security & Industrial Control Cabinet / power distribution room alarms when someone enters, human presence detection in equipment compartments Lockers, self-service equipment with presence detection Reminders for personnel staying in storage areas 4. Small Household Appliances Accessories Smart clothes dryers, electric heating towel racks, heaters with human-sensing start and stop IV. Differentiation of the Same Model LD2410B: 7×35mm long strip type, parameters are the same, but the package is different LD2412: Long-distance model, detection range of 10m+
