AU-X12
Smart, Energy Saving Detection for your spaces





AU-X12
The AutronX AU-X12 PIR Motion Sensor is a compact, energy-efficient solution that combines convenience, safety, and smart automation. Designed with a high-sensitivity infrared sensor and integrated circuit technology, this device uses human body infrared signals as the activation trigger.
It offers 360° detection with a maximum sensing distance of 12 metres, making it ideal for a wide range of indoor applications. With an adjustable LUX range of 3–2000 and versatile time delay settings, the AU-X12 adapts seamlessly to different ambient lighting conditions and user preferences.
This motion sensor is best suited for places requiring automated lighting control such as staircases, lobbies, hotel corridors, hospitals, and fire exits.

Smart Day/Night Sensing
Automatically adjusts detection based on ambient light, from complete darkness to bright sunlight.

Customisable Hold Time
Adjustable time delay from 10 seconds to 15 minutes, restarting with each motion detected.

Wide Detection Coverage
360° sensing range with up to 12 metres distance, ideal for ceiling installations between 2.2–4 metres.

Key Functional Modes

Daylight Sensitivity Adjustment
Automatically identifies lighting conditions and adjusts operation accordingly.
- “Sun” mode enables use during daylight.
- “Moon” mode restricts use to low-light conditions.
- User can set sensitivity using the LUX knob.

Auto Time Delay Reset
Extends light-on duration intelligently during continuous presence.
- Time resets with each new motion detected.
- Helps avoid unnecessary shutoff during activity.
- Delay range adjustable up to 15 minutes.

LUX Sensitivity Test
Validates sensor function under test conditions.
- Turn TIME to minimum, LUX to maximum.
- Light activates after warm-up when motion is detected.
- Use for proper placement and calibration.
Installation Guide
- Avoid facing mirrors, metal, or heat sources like vents.
- Ensure no moving objects like curtains in front of the sensor.
- Rotate and remove upper cover counter-clockwise.
- Wire connections as per wiring diagram.
- Fix base using screws and reattach the cover before powering on.
Troubleshooting & FAQs
1
Why doesn't the sensor activate in daylight?Ensure the LUX setting is turned to the "SUN" position for daylight operation.
2
Why is the light always on?Check if there is continuous movement in the detection zone or reconfigure the detection area.
3
Why doesn’t the light turn on despite movement?Verify proper mounting height and make sure the detection zone isn’t obstructed.
4
Why is the response to movement inconsistent?Avoid installing near reflective or metallic surfaces which may interfere with the sensor.
5
Can I install it myself?Installation should be done by an experienced person or licensed electrician to ensure safety and compliance.
