Product Description

The LEYDEN LS-HB759 High Bay Microwave Motion Sensor is a professional-grade 5.8GHz microwave radar occupancy sensor specially designed for warehouses, factories, workshops, parking areas, gymnasiums, industrial sheds, commercial buildings, and high-bay LED lighting applications. It automatically switches lighting ON when motion is detected and OFF after the preset hold time, reducing unnecessary power consumption while improving convenience and safety.

Unlike PIR sensors, the LS-HB759 uses advanced microwave sensing technology that detects movement through glass, plastic, and other non-metallic materials, providing reliable 360° detection over a wide area. It features adjustable detection sensitivity, hold time, and daylight threshold using DIP switches for customized operation. The sensor supports installation heights up to 15 meters with an adjustable detection radius up to 10 meters.

Ideal for:

• Warehouses
• Industrial High Bay Lights
• Manufacturing Plants
• Parking Garages
• Shopping Malls
• Staircases
• Corridors
• Logistics Centers
• Commercial Buildings
• Exhibition Halls

Amazon Bullet Points

✅ Advanced 5.8GHz Microwave Radar Technology

Utilizes high-frequency 5.8GHz microwave sensing for accurate human motion detection with 360° coverage. Detects movement even through glass and thin non-metallic materials for reliable occupancy sensing.

✅ Designed for High Bay Lighting

Suitable for installation heights from 4 to 15 meters with an adjustable detection radius up to 10 meters, making it perfect for warehouses, factories, workshops, and commercial buildings.

✅ Adjustable Detection Settings

Easily customize:

• Detection Range (20%, 50%, 75%, 100%)
• Hold Time (5 sec–30 min)
• Ambient Light Level (2–2000 Lux)
  using convenient DIP switch settings.

Box Contents

• 1 × LEYDEN LS-HB759 Microwave Motion Sensor
• Installation Manual

Installation Instructions

1. Turn OFF the main power supply before installation.
2. Mount the sensor securely on a stable ceiling or high-bay fixture.
3. Connect wiring correctly:
   • Brown → Live (L)
   • Blue → Neutral (N)
   • Red → Load Output
4. Restore power after checking all connections.
5. Configure DIP switches for:
   • Detection Range
   • Hold Time
   • Daylight Sensor (Lux)
6. Walk through the detection area to verify operation and fine-tune settings if necessary.

User Instructions

• Motion detection automatically switches the connected light ON.
• The light remains ON for the selected hold time after the last detected movement.
• Daylight sensor prevents operation when ambient light exceeds the selected Lux level.
• Adjust sensitivity and timer using the internal DIP switches.
• Suitable for LED High Bay lights up to 1000W and incandescent loads up to 2000W.

Safety Instructions

• Disconnect the electrical supply before installation or maintenance.
• Installation should only be performed by a qualified electrician.
• Install only on a stable, vibration-free surface.
• Keep the detection area free from obstructions.
• Avoid mounting near large metal objects or extensive glass surfaces that may affect microwave sensing.
• Protect the circuit with a suitable 6A fuse or protective device.
• Do not open or modify the sensor enclosure.
• Ensure wiring complies with local electrical regulations.
• Use only within the specified voltage and load ratings.
• Do not immerse the sensor in water or expose it to corrosive chemicals.
• Keep out of reach of children during installation.

Troubleshooting

Light does not turn ON

• Check power supply.
• Verify wiring connections.
• Confirm the connected load is functional.
• Check DIP switch settings.
• Ensure ambient light is below the selected Lux threshold.

Poor detection

• Remove obstacles from the sensing area.
• Verify installation height.
• Adjust detection sensitivity.
• Ensure movement occurs within the detection zone.
