Detailed Product Description

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+

 

Specifications:

Operating frequency24 - 24.25 GHz, FMCW
Antenna architecture1 transmit 1 receive (1T1R)
Breathing movementMaximum range 8m
Detection angleHorizontal ±60°
Power supplyDC 5V
Operating current79mA
