AC110-240V PIR Infrared Motion Sensor

AC110-240V PIR Infrared Motion Sensor is a mains-powered automatic detection module that switches lighting directly from the AC supply. Consequently, you need no separate DC adapter or external relay to control lamps. This PIR motion sensor detects infrared heat changes from moving people in its coverage area. Furthermore, it switches the connected lamp through a built-in relay rated for full mains load. Therefore, it is the standard choice for hallways, staircases, corridors, and porches where hands-free lighting is essential. Additionally, the wide AC110-240V input range suits both 110V and 240V regions, simplifying stocking and installation for shops and electricians alike.

Key Features of the PIR Motion Sensor:

• Direct Mains Operation: Connects straight to the AC supply and controls lamps without a transformer or DC adapter, reducing wiring and component count.
• Built-in Relay Output: The internal relay switches the load safely, supporting both incandescent and LED lamp types within rated power.
• Adjustable Time Delay: The onboard knob sets the lamp ON time from roughly 10 seconds up to 10 minutes, matching corridor or security needs.
• Adjustable Detection Range: Sensitivity control tunes detection from about 3 meters up to 8 meters, preventing nuisance triggers in small rooms.
• Day and Night Control: A lux adjustment blocks operation in bright daylight, so the sensor activates only when ambient light is low.

Technical Specifications:

• Operating Voltage: AC 110-240 V, 50/60 Hz
• Standby Power Consumption: < 1 W (typically 0.5 W)
• Maximum Load: 1200 W incandescent or 300 W LED/CFL
• Detection Range: 3 m to 8 m (adjustable)
• Detection Angle: ≈ 120 degrees (wall mount) or 360 degrees (ceiling mount)
• Time Delay: 10 seconds to 10 minutes (adjustable)
• Lux Threshold: Adjustable from about 3 to 2000 lux
• Output Type: Relay, selectable normally open or closed
• Operating Temperature: −20°C to +50°C

Mechanical Specifications:

• Enclosure Material: Flame-retardant ABS plastic housing
• Mounting Type: Wall or ceiling surface mount
• Connection: Two-wire (Live in, Load out); ceiling units use three-wire with neutral
• Device Marking: Voltage and model code printed on the rear label (e.g., AC110-240V PIR)
• Weight: ≈ 90 grams

Dimensions:

• Wall-Mount Body: ≈ 85 x 85 x 50 mm (L x W x D)
• Ceiling Dome Diameter: ≈ 100 mm
• Mounting Height: 2.2 m to 4 m recommended

Pinout and Wiring:

• L (Live In): Connect the phase wire from the mains supply to this terminal.
• LOAD (To Lamp): Connect this terminal to the live side of the lamp you want to control.
• N (Neutral): Used only on three-wire ceiling versions for the sensor itself.
• Wiring Note: Switch off the mains breaker before wiring. However, always install the sensor in series with the lamp and never exceed the rated load, or the internal relay may fail.
